Activational effect is the correct answer.
Activational effect is an impermanent hormonal effect that leads to a change in physiological activity or behavior in both humans and adult animals. For instance, when testosterone levels rise in male songbirds they become more aggressive and tend to engage in courtship behavior. Also, a pregnant woman may get more emotional than usual due to an extra level of progesterone and estrogen during pregnancy.
Answer:
The sequence would be <u>ATTCATTCA</u>.
Explanation:
Usually, when a sequence is duplicated, one of them becomes a non-coding. It's just like a computer. There can only be one specific file, or else a duplicated one will just replace the existing one, if you allow the file to do so. Same with DNA. This is why most of our DNA have no function and why we lost genetic abilities such as being able to produce our own Vitamin C.
So instead of the new gene being ATTCATTCAATTCATTCA, it's simply ATTCATTCA. You simply cannot have duplicates, just like computer files. I wish I could share an amazing video by PBS Eons giving a great explanation about genes and stuff, but sadly Brainly doesn't like such stuff, so just <em>search up in ㄚㄖㄩㄒㄩ乃乇 (ebuTouY) "genes we lost along the way" and it should be the first video that pops out.</em> Trust me, it's a great video, it's much better than my explanation.
Answer and Explanation:
<em>Q1. Assume that an organism exists in which crossing over does not occur, but that all other processes associated with meiosis occur normally. Consider how the absence of crossing over would affect the outcome of meiosis.</em>

Answer:
Explanation:
the purple allele (C) is dominant to the pink allele (c).
The frequency of C represents p while that of c represent q. Using the formula p+q= 1
The proportion of pink flower is 153/1000 = 0.153. This is also the frequency of the genotype cc (q^2).
Thud to find q which is the frequency of the c allele,
q = √0.153
q = 0.3912
From the formula p +q = 1 we can find p p = 1 - 0.3912
p which is the frequency of the C allele
p = 0.6088.
B. the proportion of all purple flowering plants that are heterozygotes and homozygotes is 847 / 1000 = 0.847
<span>The answer is
transcription. It is mediated by RNA polymerase enzyme
that reads the DNA template and makes an RNA
strand that is antiparallel and composed of nucleotides complementary to the DNA strand. This process is the first step of
gene expression. </span>
