Multiple choices :
A. test for chemicals that might poison fish and cause algae to grow
B measure the dissolved oxygen content in pond-water samples
C look for sources of pollution that may be affecting the pond
D measure the amount of light at various levels in the pond
Answer;
D. measure the amount of light at various levels in the pond
Fish in the pond feeds on the algae that grows in the pod.
Therefore; death of fish in the pond caused a large increase in algae populations.
Measuring the amount of light in the pond would not tell the student what caused the death of the fish in the pond.
Answer:
The correct answer will be option-true.
Explanation:
Follicular stimulatory hormone or FSH and inhibin are the complex proteins which play a various biological role in the reproductive system.
The FSH stimulates the secretion of inhibin from the gonads in both males (Sertoli cells) and females (granulosa layer). The production of inhibin suppresses the secretion of FSH from the pituitary gland.
The suppression of FSH directly suppresses the secretion of further inhibin and thus, option-true is the correct answer.
Answer:
Speciation was allopatric or peripatric, but would depend on the number of individuals that dispersed from the original populations.
Explanation:
The new species can be formed in one of the three ways that are allopatric, peripatric, and parapatric speciation.
The allopatric speciation gives rise to new species due to the geographical barriers present between them and the peripatric speciation occurs when a small population enters into a new habitat.
In the given question, species A is more closely related to species B as to species C. This could be due to the allopatric speciation or peripatric speciation but it would depend on the number of the individuals of the population that dispersed to a different elevation which provided a new niche.
Thus, the selected option is correct.
