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 answer 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 answer Correct answer: Supersaturated
There are three types of natural lipids: unsaturated, polyunsaturated, and saturated.
Supersaturation is a not a naturally occurring lipid.
,ATI TEAS TEST PRACTICE with
complete solutions graded A
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 answer 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.
What is the role of the Golgi apparatus in the cell?

To uptake food through the cell membrane

B.
To produce cellular respiration
C.
To provide intracellular digestion
D.
To provide transportation of materials throughout the cell -correct answer 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.
When hydrocarbon is heated, its products are carbon dioxide and water. This is an
example of which of the following?
A.
Decomposition
B.
Combustion
C.
Single replacement
D.
Synthesis -correct answer Correct answer: Combustion
An example of combustion is when hydrocarbon is heated and its products are carbon
dioxide and water. Combustion is an exothermic chemical reaction that occurs when
heat acts on oxygen or a fuel compound.
Synthesis is a reaction that causes two elements to join to form one product.
Decomposition occurs when a compound is broken down into its component parts.
Single replacement occurs when an active metal reacts with an ionic compound that
contains a less active metal to form a new compound.
