The price of a 20" television changed from $450 to $400. Find the percentage change in price.
Correct answer: - 11%
Change in price: 450 - 400 = 50
To determine the percentage change, divide the change in price by the initial price:
Multiply by 100 to determine the percentage: 0.1111 × 100 = 11.11%
Because the price decreased, the change in price is negative: - 11.11%, or about - 11%
Which of the following is not a type of natural lipid?

Mitosis is a four-stage process that creates two identical cells from one original cell.
Prophase is the first and longest stage of mitosis. In this stage, the chromosomes become visible and the centrioles separate and move to opposite poles of the cell.
Metaphase is the second stage of mitosis. In this stage, the chromosomes line up across the center of the cell and become connected to the spindle fiber at their centromere.
Anaphase is the third stage of mitosis. In this stage, the sister chromatids separate into individual chromosomes and are pulled apart.
Telophase is the fourth and last stage of mitosis. During this stage, the chromosomes gather at opposite ends of the cell and lose their distinct rod-like shapes. Two new nuclear membranes then form around each of the two regions of DNA and the spindle fibers disappear.
What is the role of the Golgi apparatus in the cell?
To uptake food through the cell membrane
To produce cellular respiration
To provide intracellular digestion
To provide transportation of materials throughout the cell
Correct answer: To provide transportation of materials throughout the cell
The Golgi apparatus is responsible for the transportation of materials throughout the cell. The Golgi apparatus, also known as the Golgi complex, Golgi body, or simply the Golgi, is an organelle found in most eukaryotic cells.
Intracellular digestion occurs within lysosomes. Uptaking food is the job of vacuoles. Cellular respiration is the function of mitochondria.

Atoms are made up of all except which of the following?
Electrons
Isotopes
Protons
Neutrons
Correct answer: Isotopes
Isotopes are atoms that have an equal number of protons but a different number of neutrons. Thus, atoms are made up of protons, neutrons, and electrons. The diagram further illustrates the composition of the atom.
To which body system does cartilage belong?
Neuromuscular system
Respiratory system
Plasma
Correct answer: Solid
Solid is the phase of matter in which molecules exert a strong attraction to one another as they move slowly relative to one another.
Plasma is the phase of matter that is made up of electrons and positive ions. Liquid is the phase of matter in which molecules exert moderate attractions to one another as they move at moderate speeds. Gas is the phase of matter in which molecules exert little or no attraction to one another because they move at high speeds.
Adrenocorticotropic hormone (ACTH) is produced by the pituitary gland. Which of the following identifies a function of adrenocorticotropic hormone?
Cortisol production
Testosterone regulation
Water balance regulation
Milk production stimulation
Correct answer: Cortisol production
The endocrine system is a set of organs that secrete hormones directly into the circulatory system. Its principle functions are hormone production and internal communication and coordination. The major glands in the endocrine system are the pineal, hypothalamus, pituitary, thyroid and parathyroid, thymus, adrenal, pancreas, and ovaries or testes. These glands send hormones through the blood to other organs and tissues in the body to control the function of that organ.
Cortisol production is a function of the adrenocorticotropic hormone (ACTH). Cortisol helps reduce stress and maintain one's blood pressure.
Milk production stimulation is a function of the prolactin hormone. Testosterone regulation is a function of the luteinizing hormone. Water balance regulation is a function of the antidiuretic hormone.
Which of the following is the metric system's basic measure of weight?
Ounce
Gram
Ton
Pound
Correct answer: Gram
A pronoun is a word that takes the place of a noun. In this case, the word he replaces the name of the person who ran over the bike.
In this sentence, bike is a noun, yellow is an adjective, and over is a preposition.
Read the following sentence, and select the meaning of the italicized word.
Insulin is endogenous and helps regulate blood sugar levels.
Located within the body
Produced within the body
Produced outside the body
Located outside the body
Correct answer: Produced within the body
The term "endogenous" means produced within the body. Insulin is produced within the body and helps regulate blood sugar levels.
The term "exogenous" means produced outside the body. The term "external" means located outside the body. The term "internal" means located within the body.
The author will typically use transition words such as one, next, another, first, and finally when writing what type of sentence?
Supporting detail
Introduction
Summary
Main idea
Correct answer: Supporting detail
Supporting details are often preceded by a transition word. This transition word helps the passage flow and keeps the reader interested in continuing to read. When looking for supporting details, keep an eye out for transition words.
Which of the following sentences is not an example of subject-verb agreement?
The consumption of oxalates can lead to the formation of calcium kidney stones. Oxalates are found in fruits, vegetables, nuts, and chocolate.
The consumption of seafood can lead to gout, as it is rich in uric acid. The consumption of carbohydrates can lead to tooth decay, as carbohydrates break down to form sugar. The consumption of salt can lead to high blood pressure.
What do ribosomes use to create proteins?
RNA
Ribosomes are made from RNAs and proteins called ribonucleoproteins. The DNA sequence in genes is copied into messenger RNA, which are then read by ribosomes to create proteins.
Express 432 cubic inches as a percentage of 1 cubic foot.
Correct answer: 25%
12 inches = 1 foot
(12 inches)³ = (1 foot)³
(12 × 12 × 12) = 1,728 cubic inches = 1 cubic foot
To find the percentage, divide 432 cubic inches by 1,728 cubic inches and multiply by 100.
What is the primary purpose of catalysts?
To increase a rate of reaction
A catalyst is a substance that speeds up a rate of reaction but does not actively participate in it. It is, therefore, left chemically unchanged at the end of a reaction.
During the glycolysis process of cellular respiration, what is produced?
Two ATP molecules, two pyruvate molecules, and two NADH molecules
During the glycolysis process of cellular respiration, two ATP molecules, two pyruvate molecules, and two NADH molecules are produced. The glycolysis process takes place in the cytosol of the cell.
When a solid substance reaches a specific temperature it will transform into a liquid. This is known as which of the following?
melting point
A substance's melting point is the temperature at which a solid substance changes into a liquid.
Boiling point is incorrect because it is the temperature at which a liquid substance begins to boil and transforms into a vapor. Malleability is incorrect because it is a metal substance's ability to be shaped. Specific heat capacity is incorrect because it is the amount of energy required to change a substance's temperature by one degree Celsius.
Anaphase is the third stage of mitosis. In this stage, the sister chromatids separate into individual chromosomes and are pulled apart.
Telophase is the fourth and last stage of mitosis. During this stage, the chromosomes gather at opposite ends of the cell and lose their distinct rod-like shapes. Two new nuclear membranes then form around each of the two regions of DNA and the spindle fibers disappear.
If one atom of element X with a charge of 3- reacts with two atoms of element Y with a charge of 1+ each, what is the charge of the final product, assuming all other variables are equal?
1 -
There is a total of 2+ and 3- charges. Adding those together, we get a final charge of 1-.
It is known that the gene that codes for male pattern baldness depends on the gene for red hair. This type of interaction between alleles is known as which of the following?
Epistasis
Epistasis is a phenomenon that consists of the effect of one gene being dependent on the presence of one or more 'modifier genes' (genetic background). Similarly, epistatic mutations have different effects in combination than individually.
A tank loses 20 cubic inches of water after 3 hours through leakage. If the tank has 80,000 cubic inches of water, how much will remain in the tank after a total of two days?
79,680 cubic inches
First, find out how many hours are in two days.
1 day = 24 hours
1 day x 2 = 24 hours x 2 = 48 hours
In 3 hours, 20 cubic inches is lost. Set up a proportion to find out how much water is lost in 48 hours.
3 hours/20 cubic inches = 48 hours/x number of cubic inches
3/20 = 48/x
3x = 960
x = 320 cubic inches
Because the question asks for the remaining quantity, rather than the amount lost, subtract this amount from the original amount in the tank.
80,000 - 320 = 79,680 cubic inches
Find the result of the following operation:
Multiply 3/4 by itself then subtract the result from 1.
7/
