Question

Differentiate between :
(a) semen and sperm
(b) implantation and pregnancy
(c) follicle and corpus luteum
(d) amnion and allantois
(e) impotence and sterility
(f) prostate gland and Cowper's gland (the nature of secretion)
(g) identical twins and fraternal twins

Answer 1

Twins are two offspring created from the same birth. Twins can be either monozygotic, meaning that they originate from one zygote, which divides and forms two eggs, or dizygotic, meaning that each twin emerges from a single egg and each egg is fertilized by its own sperm cell.

Complete answer:
(a)

Sperm	Semen
Sperm is the testicles' male gamete	The semen is the combination of sperm and fundamental discharges from the initial vesicle, prostate and Cowper's organs again.

(b)

Implantation	Pregnancy
Attachment of the embryo (blastula) in the uterus mass is the implantation	The term formed by implantation is called pregnancy.

(c)

Follicle	Corpus luteum
The follicle is the telephone bag with an egg	The rest of the follicle is the arrival of eggs in the midst of ovulation.

(d)

Amnion	Allantois
Amnion is an extension of the fetus that allows villi from the placenta around the embryo.	It is a sac-like structure which helps in exchange of gases between the embryos.

(e)

Sterility	Impotence
Sterility is the absence of sperm delivery capacity	impotence is the powerlessness of sexual intercourse.

(f)

Prostate gland	Cowper's gland
Prostate gland empties alkaline secretions into the semen in order to neutralize the acidity of the female reproductive tract.	The secretions of Cowper's gland are lubricating in nature.

(g)

Identical twins	Fraternal twins
Identical twins, for example, one producing zygote divides, they are born from one ovum and grow into two infants,	fraternal twins are delivered when two ova are fertilized by two sperms at same time.

Note: To cure infertility, assisted reproductive technology (ART) is used. It entails therapies for fertility that work with both the egg of a woman and the sperm of a male. This works by extracting eggs from the body of a woman. To produce embryos, the eggs are then combined with sperm. The embryos are then inserted back into the body of the woman.
