A
The daughter cells of Amoeba and the bud of yeast are smaller than their respective parent cells.

B
The daughter cells of Amoeba and the bud of Yeast are of the same size as their respective parent cells.

C
The daughter cells of Amoeba are bigger than the parent cells but bud of yeast is smaller than the parents.

D
The daughter cells of Amoeba are smaller than the parents but bud of yeast is larger than the parents.

Question 7
1 / -0

Parthenogenesis is the development of a female egg into a new individual without the contribution of a male set of chromosomes.
In a hypothetical pond, two populations of fish are found; one reproduces through sexual reproduction, the other through parthenogenesis. Initially, the parthenogenetic fish are a larger population when the pond is first studied. However, researchers soon observe that the parthenogenetic fish are more frequent hosts for a new blood-borne parasite than the sexually reproducing fish. As a result, the sexually reproducing population increases and the parthenogenetic population decreases.
Which of the following best explains the reason for the shift in population numbers?

A
Sexual reproduction increases genetic variation. Some individuals in the sexually reproducing population will be adapted to a change in environment, in this case, the addition of a new parasite. These individuals will survive and reproduce at a higher rate than those affected by the parasite.

B
The asexual fish are more susceptible to the parasites because they are an all female population, and typically less aggressive. The sexually reproducing population is protected by aggressive adult males fighting off the invading parasites.

C
The asexually reproducing fish are intentionally reducing their population density as a mechanism to slow the spread of the parasite.

D
The sexually reproducing population can reproduce faster than the parthenogenesis population, allowing them to produce so much offspring that not all can be affected by the new parasite.

Question 8

A) Sexual receptivity occurs all through the menstrual cycle.
B) Estrus prepares the female reproductive tract for copulation.

Both A and B

C
Both A and C

D

A
Lion, deer, dog and cow

B
Cow, monkey, elephant and ape

B
Inflammatory response of WBC

C
