ATI TEAS TEST PRACTICE QUESTIONS AND ANSWERS 100% ACCURATE.
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 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?
A.
, 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: 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: 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.
When is a double covalent bond formed?
A.
