The correct answer for the above question is the ejaculatory ducts. The male urethra is divided into three regions, one of them is the prostatic urethra which is the proximal portion that passes through the prostrate gland. It receives the ejaculatory duct, which contains sperm and secretions from the seminal vesicles, and numerous ducts from the prostrate glands.
Genetics, blood type gene has two alleles, each allele has genotype A, B or O. The A and B are dominant, and O is recessive. So allele A combined with allele O is type A. Similarly, BO is type B, AA is type A, BB is type B, OO is type O, and AB is typeAB.
If both parents have type A blood, then the alleles could be AA or AO, thus the allele A frequency is 75%, allele O frequency is 25% for both parents.
So the chance of alleles OO is 25% × 25% = 6.25%,
alleles AA is 75% × 75% = 56.25%,
alleles AO is 75% × 25% = 18.75%,
alleles OA is 25% × 75% = 18.75%.
Since AA, AO and OA are blood type A, and OO is blood type O, thus their child has 6.25% chance to be blood type O and 93.75% chance to be blood type A.
The +/- is called the rhesus factor, with + being dominant, and - being recessive.
So if both parents are -, the kids are always -, otherwise the kids might be + or -.

Answer : Option A) He asked what would happen if he deliberately inoculated someone with cowpox fluid from another person.
Explanation : Edward Jenner wanted to know what would happen if he deliberately inoculate the cowpox fluid from some person to another. He tested this experimental results and later on came up with the hypothesis. Which roughly state that someone will not get smallpox because they already had cowpox.
Answer:
Compare mitochondria to the digestive system. The cytoskeleton is similar to the skeletal and muscular system. They both provide structure and allows for movement within the cell. The cell membrane is similar to the integumentary system. They both separate and protects the internal structures from the external environment and it regulates water loss.
