Answer:
Prostate gland
Explanation:
Prostate gland is an exocrine gland of the male reproductive tract that secretes alkaline fluid which is about 30% of seminal fluid. The role of the prostate and its secretion is to nourishes and protects sperm.
This gland vary in size and vary in secretions among different species.
The activity of the prostate is under the control of hormones, mostly testosterone (its metabolite dihydrotestosterone), produced by the testicles.
The answer for this question is b :)

If there are 270 total offspring, we would expect
As flies with one curly allele (Cy) & one normal allele (Cy+) have curly wing, curly wing is dominant to normal wing.
Two curly-winged flies produce 203 curly-winged & 98 normal-winged flies. This is almost in 2:1 ratio for curly wings: normal wings. But expected ratio in offspring when two heterozygous flies are crossed is 3:1.
Only possibility is that homo-zygous for curly gene is lethal, i.e., CyCy genotype is lethal. So, if a curly-winged fly is survived its genotype will be Cy Cy+. Genotype of normal-winged fly will be Cy+ Cy+
<h3>The cross between one curly-winged & one normal-winged fly is shown in below Punnett square.</h3>
Gametes Cy+ Cy+
Cy Cy Cy+ (Curly wing) Cy Cy+ (Curly wing)
Cy+ Cy+ Cy+ (Normal wing) Cy+ Cy+ (Normal wing)
We find that expected ratio for curly & normal-winged fly is 1:1. Thus, among 270 offspring we will expect
= 135 offspring of curly-winged.
