ATI TEAS TEST PRACTICE QUESTIONS
AND ANSWERS
The price of a 20" television changed from $450 to $400. Find the percentage change in
price.
A.
-10%
B.
-11%
C.
-13%
D.
-15% - Correct Answers -Correct answer: -11%
Change in price: 450 - 400 = 50
To determine the percentage change, divide the change in price by the initial price:
50 = 0.1111
450
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?
A.
Supersaturated
B.
Polyunsaturated
C.
Saturated
, D.
Unsaturated - Correct Answers -Correct answer: Supersaturated
There are three types of natural lipids: unsaturated, polyunsaturated, and saturated.
Supersaturation is a not a naturally occurring lipid.
Unsaturated and polyunsaturated lipids have one or more double bonds between
carbon atoms of fatty acid chains; saturated lipids share no such double bonds.
A common example of supersaturation is rock candy, which is created from a
supersaturated sugar solution.
Which of the following is not true of mitosis?
A.
Daughter cells are different than parent cells
B.
Daughter cells are identical to parent cells
C.
It produces daughter cells
D.
It occurs only in eukaryotic cells - Correct Answers -Correct answer: Daughter cells are
different than parent cells
Mitosis is a cell cycle during which a parent cell produces an identical daughter cell. It
has four main phases: prophase, metaphase, anaphase, and telophase. Since the
parent and daughter cells are identical, both diploids and haploids can undergo mitosis.
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.
