TEA [102]

Answer:

What is a good example of a response-based definition of stress?

Bruce experiences stress because his heart rate increased when he noticed Jack had a knife.

Explanation:

Stress can have many different causes. In this case, it is produced by seeing danger in Jack by having a knife. His heart rate increases because this is a common response in stress, which would enable people to scape. It is important to control stress lebels.

A stressor is distinguished as a threat. If someone anticipates that it could lead to some kind of harm, loss, or other negative consequence. However, if you see the positive side and believe that it carries the potential for gain or personal growth, it would be appraised as a Challenge.

Which of the following is true about offspring resulting from a cross that yielded TT, Tt, TT, ans Tt?
Vera_Pavlovna [14]

Additional detail found elsewhere: (T = Tall and t = short)

Answer:

All are expected to be tall

Explanation:

We are told that the T allele produces the tall trait, and the t allele produces the short trait.

Because the tall allele is denoted by an uppercase letter, it means it is the dominant allele, meaning if it is present even in one copy, the trait will be expressed. This is in contrast to the recessive short allele, 2 copies are needed for the trait to be expressed.

Individuals have 2 copies of every gene. Offspring that are TT, Tt, TT, and Tt all have at least one copy of the T (tall allele). Because this is the dominant allele, that means all of these offspring would be expected to be tall.
