Weekly Quiz Competition

Question 1
1 / -0

Choose the correct answers from the alternatives given.
Development cannot proceed properly unless each stage is successfully completed before the next begins, starting with

A
gamete formation

B
gastrulation

C
fertilization

D
cleavage

Solution

In the process of reproduction in any organism, the first step is the formation of the male and female sex gametes. These lay the first step toward the process of reproduction. Next step is the fertilization of the male and female gamete, which is followed by the development of the zygote/embryo formed.
So the correct option is 'gamete formation'.
Question 2
1 / -0

Which of the following is an unpaired gland in human body?

A
Prostate gland

B
Seminal vesicle

C
Cowpers gland

D
Bartholins gland

Solution

The prostate is a gland that produces the fluid that carries sperm during ejaculation. The prostate gland surrounds the urethra, the tube through which urine passes out of the body. Prostate enlargement happens to almost all men as they get older. An enlarged prostate is often called benign prostatic hyperplasia (BPH).
So, the correct answer is 'prostrate gland'
Question 3
1 / -0

Choose the correct answers from the alternatives given.
In many embryos, differentiation begins at the following stage

A
Cleavage

B
Blastula

C
Gastrula

D
Neurula

Solution

The mitotic division starts as the zygote moves through the isthmus of the oviduct called cleavage towards the uterus and forms 2, 4, 8 16 daughter cells called blastomeres. The embryo at 8-16 celled stage is called a morula. Thus the division starts at the cleavage.
So the correct option is 'Cleavage'.
Question 4
1 / -0

Refer to the given graph showing levels of different hormones (P-S) during menstrual cycle in a normal woman
Identify the hormones P-S and select the incorrect statement regarding them

A
$$R$$ stimulates the ovarian follicles to produce estrogen during proliferative phase while $$Q$$ stimulates the corpus luteum of the ovary to secrete progestrone

B
Menstrual phase is caused by the reduction of $$P$$ and $$S$$

C
Proliferative phase is characterised by increased production of $$S$$ whereas secretory phase is characterised by increased production of $$P$$

D
In males, $$Q$$ causes spermatogenesis whereas $$R$$ stimulates Leydig's cells to secrete testosterone
Question 5
1 / -0

A sex gland which contributes fluid containing fructose that provides spermatozoa energy for swimming and hormone prostaglandins that stimulate actions in the female reproductive tract to aid sperm-ovum interaction is

A
Cowper's gland

B
Prostate gland

C
Seminal vesicle

D
Preputial gland
Solution
The seminal vesicles are a pair of sac-like structures near the base of the bladder. Their ducts join the vasa deferentia to loan the ejaculatory ducts. They produce an alkaline secretion that contains fructose, prostaglandins, and clotting proteins that are different from those in blood.
The prostaglandins stimulate uterine contractions and thus may help the sperm to move towards the female's oviducts, where fertilization takes place. Fructose is present in the seminal fluid and is not produced anywhere else in the body. It provides energy to sperms for moving.
So, the correct answer is 'Seminal vesicle'.
Question 6
1 / -0

The term "inbreeding depression" is related to ______________.

A
increased fertility and productivity

B
increased milk production

C
reduced fertility and productivity

D
reduced milk production.

Solution

Continued inbreeding, especially close breeding usually reduces fertility and even productivity. This is called inbreeding depression.
Question 7
1 / -0

In most mammals, the testes are located in scrotal sac for _________.

A
More space to visceral organs

B
Spermatogenesis

C
Sex differentiation

D
Independent functioning of kidney

Solution

In mammals, scrotal sacs (containing testes) act as thermoregulator, maintaining the temperature of the testes $$2^oC$$ lower than that of the body. This temperature is required for the spermatogenesis to occur otherwise, the sperms could be destroyed by high temperature, resulting in sterility.
Question 8
1 / -0

Sertoli cells are regulated by the pituitary hormone known as __________.

A
LH

B
FSH

C
GH

D
Prolactin

Solution

FSH stimulates Sertoli cells of the testes to secrete an androgen liming protein that concentrates testosterone in the seminiferous tubules.
Sertoli cells also secrete a hormone called inhibin which suppresses FSH synthesis.
Question 9
1 / -0

The function of the secretion of prostate gland is to _____________.

A
Inhibit sperm activity

B
Attract sperms

C
Stimulate sperm avidity

D
None of these

Solution

The prostate gland is a single large gland that surrounds the urethra. It produces a slightly alkaline, milky secretion which forms 25% of the volume of semen. It possesses citric acid, enzymes (add phosphatase, amylase, pepsinogen) and prostaglandins. Secretion of the prostate gland nourishes and activates the spermatozoa to swim.
Question 10
1 / -0

In humans, at the end of the fist meiotic division, the male germ cells differentiate into the _______________.

A
Spermatids

B
Spermatogonia

C
Primary spermatocyon

D
Secondary spermatocytes

Solution

During spermatogenesis, at the end of first maturation division (reductional division or meiosis), the primary spermatocyte divides into two haploid daughter cells called secondary spermatocytes.
