Question 1
Which term means inhibiting the growth of microorganisms?
Correct Answer:
Antimicrobial
Explanation:
Antimicrobial is the term that covers substances that act against microorganisms, either stopping their growth or killing them. In practice, antimicrobials include antibiotics, antiseptics, and disinfectants, and they can be bacteriostatic (inhibiting growth) or bactericidal (killing). The idea of inhibiting growth fits squarely under this broad category, whereas the other options refer to anatomy, a diagnostic procedure, or a body system and do not describe actions against microbes.
Question 2
According to Jenna Barber, DVM, how often should dogs be tested for heartworm disease?
Correct Answer:
Once a year
Explanation:
Testing for heartworm disease is most appropriately done on a yearly basis. The reason is that heartworm can be present without obvious symptoms, and the antigen test detects mature, circulating worms. Even with monthly preventives, infections can occur if a dose is missed, a product fails, or a dog is exposed in high-risk areas. A yearly test provides ongoing surveillance to catch any new infection early, before significant heart or lung damage develops, and aligns with common veterinary guidance like that of Jenna Barber, DVM. More frequent testing isn’t usually necessary for the average patient, and less frequent testing risks missing a new infection.
Question 3
The term that describes the scientific study of social behavior in animals and humans is Sociobiology.
Correct Answer:
Sociobiology
Explanation:
Sociobiology is the scientific study of social behavior in animals and humans, examining how genetics and natural selection shape interactions, cooperation, mating systems, aggression, and social organization. It uses an evolutionary lens to explain why certain behaviors persist because they improve survival and reproductive success, across different species and in humans alike. This perspective differs from psychology, which centers on mental processes and behavior without necessarily tying them to evolutionary history. The other terms aren’t fields of study: a colony is a social group, and parasites are a type of organism, leaving sociobiology as the correct term.
Question 4
Which cells carry oxygen in the body using hemoglobin?
Correct Answer:
Red blood cells
Explanation:
Oxygen transport in the bloodstream is carried by hemoglobin within red blood cells. Hemoglobin binds oxygen in the lungs and releases it to tissues where it’s needed, using the iron-containing heme groups to carry up to four oxygen molecules per hemoglobin molecule. Plasma carries only dissolved oxygen and is not the primary transport method, while platelets and white blood cells perform clotting and immune functions, not oxygen transport.
Question 5
Which human disease is related to the simian immunodeficiency virus (SIV) that affects non-human primates?
Correct Answer:
HIV
Explanation:
SIV in non-human primates is the close relative of the human virus that causes infection in people. When this virus crossed into humans, it became HIV, the human immunodeficiency virus. HIV is the agent that attacks the immune system, and if not treated, it can progress to AIDS, the syndrome of severe immune deficiency. The other options are caused by entirely different pathogens and aren’t linked to SIV/HIV.
