Answer:

For several months, weighing and measuring the pups every week

Explanation:

This is to control variables and keep a measurable set of data that can prove or disprove the theory they had developed, and also to isolate cases that can't be attributed to the experiment they had carried out, like puppies loosing weight due to illnesses, or behavioral factors.

Sergeeva-Olga [200]
<h2>Scientist Observing changes </h2>

If the population of the species is significantly decreasing then the species could become extinct. The decline in population is due to some factors like less immigration, aging, and decreasing fertility rates. But the most is due to less immigration which causes to decrease population. The extinction of population can be prevented by some serious actions which should be taken government.

Anna007 [38]

Answer:

A) They have low-maintenance and are easy to keep track of for mutations.

B) The deduction can be "Single Gene Mutation"

Explanation:

After examining the example given in the question on Neurospora crassa and the details about how they reproduce, the following points can be made regarding the questions;

A) It is stated that they form a colony in time and that they are asexual spores and the first reason to choose them would be because they contain somatic cells (which refer to the cells other than reproductive cells) and non-motile gonidia which can multiply by dividing themselves and these properties make the colony's maintenance easy. And since they multiply by division, it is easier to keep track of the occuring mutations.

B) Given the information in the question that the mating is between an albino strain and a wild type, and then between two albino strains which have the same genotype. The results indicate that the strains have gone through single gene mutation during the process.

I hope this answer helps.
