   2023 Audio GED Prep Language Arts Literary Devices

   GED Prep Language Arts Literary Devices GED Prep language Arts Literary devices are like the tools at an author’s disposal. A simile is a comparison using the words “like” or “as”. A metaphor is also a comparison, stronger than a simile that does not use “like” or “as”, but usually uses a form of the verb “to be”.

A simile is a comparison using the words “like” or “as”. A metaphor is also a comparison, stronger than a simile that does not use “like” or “as”, but usually uses a form of the verb “to be”. Descriptive language is when an author uses adjectives and adverbs to paint a vivid picture with specific details. An author needs to find a balance between using too much and too little description. Alliteration is a device often used in poetry in which words have the same initial sound. Allusion is when an author makes a reference to another work in order to create a desired effect. Hyperbole is using exaggeration to make a point, such as saying that “I was so hungry I could eat a horse.” Personification is when an author gives human attributes to an inanimate object, such as describing a fire as “running”. An allegory is a story in which the characters, settings, or events have a deeper symbolic meaning such as George Orwell’s “Animal Farm”.

   GED Prep Mathematics Lesson Fraction 2023

   Audio GED Prep Mathematics Lesson Fractions GED Prep Mathematics Lesson Fractions, a fraction shows a part of a whole. They are usually shown by a top number, called the numerator, and a bottom number, called the denominator.

They are usually shown by a top number, called the numerator, and a bottom number, called the denominator. Between the numerator and the denominator, there is a slash, either a straight line(—) or a slash (/). The denominator shows how many parts are in a whole, (1) and the numerator shows how many parts you have. There are several ways that you will see fractions used. The reciprocal of a fraction is when you switch the numerator and the denominator. For example, 3/4 and 4/3 are reciprocals. Types of fractions First, there are simple fractions. In simple fractions, the numerator is smaller than, or equal to the denominator, meaning that you have a part of a whole, or exactly one whole thing. Then, there are complex fractions, in which the numerator is larger than the denominator. You can write these out like a normal fraction, or write them as a mixed number, which consists of an integer and a fraction side by side. If you have a complex fraction, you have at least one whole thing or more, and part of another whole. Simplifying fractions/equivalent fractions Sometimes, a fraction can be simplified. This means that it could be written as a fraction that has a smaller numerator and denominator without changing its value. If both numbers of a fraction can be divided by the same number, then the fraction can be simplified. This means that there are many fractions that are equal to the same part of a whole. For example, if you divide a whole into four parts, and you have two parts out of the whole (2/4), that is the same as diving a whole into two parts and having one of the two parts. (1/2). Both 2/4 are ½ are exactly half of the whole or 50%. You can divide both 2 and 4 by 2 to get 1 and 2 respectively. If you cannot divide the numbers of a fraction by the same number, then the fraction is as simple as possible. For example, the fraction 7/8 cannot be divided by the same number, and so is completely simplified. Converting fraction to mixed number/vice versa Sometimes, it will be useful to convert a fraction to a mixed number or from a mixed number back into a fraction. For sake of ease, first simplify the fraction if possible. To convert a fraction to a mixed number, you must first see if the numerator is greater than the denominator.If it is not, then you cannot create a mixed number because you do not have more than one whole. If the numerator is greater, then subtract the denominator from the numerator. For example, if the fraction 9/8 then you subtract 9 – 8 = 1. The result is you new numerator. You then put a large number one next to the fraction to show one whole unit. So, 9/8 becomes 1 1/8. Then, you need to check if the numerator is still greater than the denominator. In this case, it is not, and so you are done. If,

   2023 Audio GED Prep Mathematics Lesson 1

   Audio GED Prep Mathematics Lesson Audio GED Prep Mathematics will include: An integer is a positive or negative number that does not have a decimal or fraction. These are what are used when counting objects. See more below: The full GED Audio Course is available at: (https://series7podcast.gumroad.com/l/wHvQ) (https://series7podcast.gumroad.com/l/wHvQ) http://www.audiogedprep.com (http://www.audiogedprep.com) Full Course is available at: https://gumroad.com/l/wHvQ (https://gumroad.com/l/wHvQ) Lesson Summary: Audio GED Prep Mathematics Lesson 1 Integers and Decimal Definition of an integer/decimal An integer is a positive or negative number that does not have a decimal or fraction. These are what are used when counting objects. When a decimal point is present, everything to the left is an integer, and everything to the right is a decimal. A decimal is a part of an integer. Numbers closer to the decimal point are larger, which is the opposite of how it is for integers. Positive and negative numbers In math, you might see what is called a number line, in which the middle point is marked 0, and numbers are listed as points on a line going out to the left and right. The number 0 is neither positive nor negative, and everything to the right of 0 is a positive number, and everything to the left of 0 is a negative number. You indicate a negative number by putting a dash/minus sign in front of it. Negative numbers have their own set of rules. When you add a negative number, it is the same as subtracting that same number. If you subtract a negative number, it is the same as adding that same number. Just remember that these two are reversed. When you multiply two negative numbers as well, you will always get a positive number. (The minus signs cancel each other out.) If, however, you multiply a negative number and a positive number, you will always get a negative number. Addition Addition is when you take two numbers and combine them to create a new total. Addition is indicated by a plus sign, which looks like a small cross. When you speak an addition equation, you say “five plus six is eleven”, which is the same as 5 + 6 = 11. Subtraction Subtraction is when you take two numbers and take one away from another to create a new total. Subtraction is indicated by a minus sign, which looks like a small dash. When you speak an addition equation, you say “ten minus nine is one”, which is the same as 10 - 1 = 9. Multiplication Multiplication is when you take one number and multiply that number by another number. Multiplication is indicated by a small X or sometimes an *. When you speak a multiplication equation, you say “four times three is twelve”, which is the same as 4 x 3 = 12 or 4 * 3 = 12. Division Division is when you take one number and divide into the number of parts indicated by a second number. Division is indicated by a division sign (÷) or sometimes by a slash (/). When you speak a division equation, you say “ten divided by two equals five”, which is the same as 10 ÷ 2 = 5 or 10/2 = 5. Absolute value Absolute value refers to how many units a number is worth, no matter whether it is positive or negative. You can mark the absolute value by putting vertical lines around a number, such as |2|. The absolute value of ten (|10|) is ten, and the absolute value of negative 10 (|-10|) is still 10. Comparisons Sometimes in math, you need to talk about whether something is gre...

   2023 Audio GED Prep Science Lesson 2 Biology 2023

   Audio GED Prep Science Lesson Biology   2 Lesson Summary: In this lesson we talk a bit about Biology There are two main ways in which organisms obtain the energy that they need in order to exist from day to day. There are some organisms like humans who eat other plants and animals in order to create energy. These organisms take in oxygen and expel carbon dioxide. Then, there are other organisms that you a process called photosynthesis in order to convert the light from the sun into usable energy. These organisms, mostly plants, take in carbon dioxide and expel oxygen. Thus, both kinds of organisms are in a mutually-beneficial relationship that helps support all life. ADP and ATP ATP (Adenosine triphosphate) is a molecule in the body that cells use for energy transfer. When an organism processes food, it creates ATP in cells. Each molecule of ATP has three branches or phosphate groups that can be broken off. When a cell breaks one of these bonds, ATP turns into ADP (Adensoinediphosphate), which chemical reaction creates energy. Notice that “tri” means three and “di” means two. The energy created then powers cells to continue their processes. Photosynthesis the Biology of Photosynthesis is a process that plants and similar life forms use to create energy. Organisms who use photosynthesis contain a chemical called chlorophyll which lends a green color to these life forms. They are green because they use the energy from the blue and red wavelengths of light, but not green. Red and blue get absorbed, but green stays. During photosynthesis, sunlight strikes the chlorophyll in plants in cells that all plants have that are known as chloroplasts. In these cells water and carbon dioxide combine using the energy from sunlight to create glucose (sugar) and oxygen. Water is made of two hydrogen atoms and one oxygen (H2O) and carbon dioxide is made of one carbon atom and two oxygen atoms. (CO2) Glucose is made of carbon, hydrogen and oxygen (C6H12O6). The glucose is used for energy and the oxygen is let off as a waste product, to be used by animals who need oxygen to create energy instead of carbon dioxide. DNA DNA (deoxyribonucleic acid) is the molecule that creates the blueprint to make living cells.In Biology almost all living organisms use DNA. It contains instructions based on different combinations of chemicals called bases: adenine (A), guanine (G), cytosine (C) and thymine (T). These bases fit together with each other to create what are called base pairs, which, along with a sugar molecule and phosphate molecule, create the “rungs” on the ladder of DNA. A pairs with T, and C with G. The base pairs form the “rungs” and the sugar and phosphate form the vertical sides of the ladder, which is then twisted around. A single piece of human DNA contains about 3 billion of these base pairs, and 99 percent of these base pairs are the same on most people, with only the 1 percent making us unique. DNA is a powerful substance that is able to make copies of itself in order to spread the necessary instructions to other cells so that more copies of cells can be made. When the body “reads” DNA, it receives instructions to make a certain protein, called a gene, and these genes are what determine the properties of a life form, from hair color, to eye color, to skin color, to less obvious things such as what diseases a person might be prone to in life. There are over 20,000 genes in humans, which together make up what is called the human genome. Scientists have mapped this genome in order to better help people predict what their genes will cause. RNA RNA stands for ribonucleic acid, and it is similar to DNA. It is made up of nucleotides with a nitrogenous base, a sugar and a phosphate, just like DNA. Unlike DNA,

In this case, you would get 2 1/8. Now that the numerator is larger than the denominator, you are done.

The period is used at the end of a declarative sentence and after some abbreviations such as “Mr.” or “A.M.” The exclamation point shows strong emotion and is used after a strong command or interjection, such as “No!” Exclamation points should only be used sparingly and never more than one at a time. The question mark is used to show that a sentence is a question. You should not use more than one or combine it with an exclamation point in formal writing. Only use a question mark after a direct question. Commas are used in a variety of situations. They can be used in a list of items, separating stings of numbers, elements in dates and addresses, and used to separate introductory material from the rest of the sentence. They are also used before coordinating conjunctions such as “but”, “and” and “yet” when they are used to link to independent clauses and between a person and their title, such M.D. or Jr. When using quotations, a comma should separate the quotation and the rest of the sentence. When addressing a person, you should set his or her name off by commas, or when using an appositive, which is a phrase which adds more information in a sentence. The semicolon can be used when separating items in a complex list, such as a list of places that include cities and states. You can also use a semicolon to connect closely related independent clauses where you usually can use “because”. Quotation marks are used to show direct quotes. They always come in pairs. They can also be used to show that certain words are a title or a short story, song, or other creative work. You should start a new paragraph whenever a new person starts speaking. Do not use quotation marks for indirect quotes. Apostrophes are used to show possession and to create contractions. You can add ‘s to a noun to show possession, or just ‘ when the noun already ends in s. When forming contractions, apostrophes show where a letter or letters were omitted. A dash or a hyphen is used to connect multi-word adjectives, such as well-known, and to connect complex numbers such as twenty-six or seventy-two. It can also be used to break up a word between lines. It also sets off some prefixes, such as ex- and all-. An ellipsis is shown by three equally spaced dots and means that some words in a quotation have been omitted. It can also be used in dialogue to show that someone’s voice is trailing off. Parentheses are used for material in a sentence that is not emphasized in a sentence and usually should have no punctuation between the two parentheses.

    Life Science: Anatomy and physiology Nervous system The nervous system is made up of the brain, the spinal cord, and the nerves. Electrical impulses are sent from the brain, travel down the spinal cord, and are sent out to the nerves. There are different kinds of nerves, those that control conscious motions and those that control unconscious processes. The nerves are what sense pain as a defense mechanism for your brain. They can sense a variety of sensations, such as hot and cold, pressure, and movement, all of which help the brain process information. It is important to care for the nervous system, because once damaged, nerves cannot be repaired. Skeletal and muscular system The skeletal and muscular system work together in order to give the body shape and structure and to allow the body to move. The human body has over 200 bones, which are made up of a hard outer part and a softer inner part called marrow, which is responsible for red blood cell production and other functions of the immune system. The points where bones connect and move against each other are called joints. There are various types of joints, from the hinge joint in the knee that just opens and closes to the ball and socket joints in the arms, which allow for a full rotating range of motion. Ligaments are flexible bits of tissue that connect bones to other bones. Tendons are similar bits of tissue that connect bones to muscles. There are several different kinds of muscles, including voluntary muscles and involuntary muscles.  Voluntary muscles are ones that are controlled directly by you thinking about them. They include in the muscles in your arms and legs that allow you to walk or to pick something up. Involuntary muscles are ones regulated by the brain that you do not have conscious control over. The heart is an example of this. Your heart keeps beating whether or not you think about it, and you cannot stop it by thinking about it either. Respiratory system The respiratory system is the system that takes in oxygen into the body and oxygenates the blood so that oxygen can travel throughout the body. It then takes in carbon dioxide and expels it from the body. The respiratory system consists of the lungs, the mouth, the throat, and the sinuses. The lungs are full of tiny sacs called alveoli, which make the exchange of oxygenated blood and unoxygenated blood. Circulatory system The body’s circulatory system is responsible for carrying blood throughout the body. the blood is filled with oxygen in the heart, and is then pumped out into the body through blood vessels called arteries. Blood is pumped to the cells and is transferred to blood vessels called veins through tiny blood vessels called capillaries. Veins then carry the unoxygenated blood back to the heart where it can pick up a new round of oxygen. You body performs this operation thousands of times a day without you having to think about it. In addition to carrying oxygen to cells, blood also transports nutrients to cells, takes away waste, and transport immune system cells to fight pathogens throughout the body. If a blood vessel is broken, there are tiny cells in blood called platelets, which causes blood to clot together in order to plug the break. Digestive system The digestive system is responsible for processing the food that brought into the body. It separates nutrients and other useful materials from waste material. This process is called digestion. Digestion begins in the mouth where glands create saliva, which starts to break down food. Food then passed down a muscular tube called the esophagus into the stomach. In the stomach, food is broken down by stomach acid and is then passed into the small intestine. Here,
