Which of the following is a characteristic of the human organism?
A. Autotrophic with a genome stored in DNA
B. Heterotrophic with a genome stored in DNA
C. Autotrophic with a genome stored in DNA
D.Heterotrophic with a genome stored in RNA - CORRECT ANSWERS B.Heterotrophic with a
genome stored in DNA
Humans consume rather than manufacture nutrient molecules (heterotrophic), and human
genes are encoded in DNA
Which of the following cell types is responsible for the production of soluble antibodies?
A. Cytotoxic T-Cell
B. macrophage Cell
C. Helper T-cell
D. B-Cell - CORRECT ANSWERS D. B-cell
The production of antibodies by B-cells is part of the humoral response to antigens.
Cytotoxic T-cells destroy pathogens and infected cells.
Macropahges ingest and digest both non-self and dead cells.
Helper T-clls help cytotoxic T-cells and other immune cells.
A person is suddenly frightened. Which of the following reactions occurs next?
A. liver cells absorb glucose from the blood stream.
B. Blood vessel supplying skeletal muscles constrict.
C. Blood Vessels supplying the intestines dilate.
D. Liver cells release glucose into the blood stream. - CORRECT ANSWERS D. Liver cells
release glucose into the blood stream.
Epinephrine causes liver cells to break down glycogen, which causes an increase in sugar in
the blood stream.

Unlike skeletal muscle, cardiac muscle is highly resistant to lactate-mediated fatigue because
cardiac muscle:
A. uses aerobic respiration in mitochondria for energy
B. operates with electrical energy supplied by the sinoatrial (SA) node
C. primarily metabolizes glucose using the fermentation pathway
D. does not need oxygen for the production of energy - CORRECT ANSWERS A. uses aerobic
respiration in mitochondria for energy
Aerobic respiration (oxidative respiration) is almost exclusively used by the heart. The
byproducts of this type of respiration are water and carbon dioxide, not lactate.
The SA node, also known as the pacemaker, produces electrical impulses for heart
contraction.
The lactose-producing fermentation pathway operates during oxygen deprivation in the
skeletal muscle.
The heart is highly sensitive to oxygen deprivation, and requires a steady oxygen supply for
ATP production by oxidative phosphorylation during aerobic respiration.
Ca+H2SO4
Which of the following statements correctly describes the product of the reaction above?
A. Calcium sulfate
B. Hydrogen sulfide
C. Calcium sulfide
D. Hydrogen sulfate - CORRECT ANSWERS A. calcium Sulfate
Calcium and sulfuric acid react to produce calcium sulfate and hydrogen gas
On an imaginary planet called Alpha Vega, purple eyes (F) are dominant over pink eyes (f).
Which one of the following combinations will produce only offspring with pink eyes?
A. Ff x ff
B. Ff x Ff
C. FF x ff
