Kobotan [32]

Some students feel distressed only in test situations. They might be said to suffer from Acute Stress.

Answer: Option B

<u>Explanation:</u>

Stress is your body's reaction to specific circumstances. It's abstract, so something that is distressing for you may not be unpleasant for another person. There is a wide range of sorts of stress and not every one of them is terrible. Stress can enable you to act rapidly in a crisis or help you comply with a time constraint.

Acute stress is the most widely recognized sort of pressure. It's your body's prompt response to another test, occasion, or request, and it triggers your battle or flight reaction.

How does evolution lead to both the diversity and the unity of life?
gogolik [260]
<span>Simple. All of the millions of different life forms (the diversity of life) have come about by natural selection, whereby random mutations in the genes have either succeeded or failed. But all life can be traced back to a common single-celled origin. Thus we have the unity of life where we (possibly) share more than 50 % of our DNA with a crocodile.eg:analogous organs, homologous organs.</span>

mr_godi [17]

Answer:

True

Explanation:

The Drosophila like the mammals possess X and Y chromosomes but as in males in which the XX is female and XY is male, the sex In Drosophila is not determined by the presence of Y chromosomes as a male determining factor are present on the autosomes.

However, the Y chromosome is important for males as they are involved in the formation of the sperms therefore the presence of Y is important. In the given question if the allele is present ion the Y chromosome which can reduce the size therefore the allele is passed on to the males only ans no females.

Thus, true is the correct answer.

the fly is female (Bridges 1921, 1925). Thus, XO Drosophila are sterile males. In flies, the Y chromosome is not involved in determining sex. Rather, it contains genes active in forming sperm in adults.
