Weekly Quiz Competition

Question 1
1 / -0

Sugar fructose is present in the secretion of

A
Prostate gland

B
Perineal gland

C
Cowper's gland

D
Seminal vesicles

Solution

The male accessory glands include paired seminal vesicles. The seminal vesicles are narrow, long pouches with muscular tissue in their wall, lying between the urinary bladder and rectum. Sugar fructose is present in the secretion of the seminal vesicle. Fructose is an energy source used by sperm. This fluid is known as semen. Sixty percent of semen is produced by seminal vesicles.
Thus, the correct answer is 'Seminal vesicles'.
Question 2
1 / -0

Human female reaches menopause at the age of about

A
$$25$$ years

B
$$35$$ years

C
$$50$$ years

D
$$70$$ years

Solution

Ovaries in woman stop their action at an early age by 40 for about 2%. Ovarian failure occurs at an average age of menopause is 50 years old.
So, the correct answer is '50 years'
Question 3
1 / -0

Fixing up of blastocyst in the wall of uterus is

A
Impregnation

B
Placentation

C
Implantation

D
Fertilization

Solution

The fixing of the blastocyst in the wall of the uterus is known as implantation. The implantation takes place after seven days of fertilization.
Placentation is the formation of placenta which links the foetus to the mother and is very essential for the growth of the foetus.
The fertilization or impregnation is the fusion of the male and female gamete to form the zygote.
So, the correct option is 'Implantation'.
Question 4
1 / -0

Which one is correct for mammalian testis?

A
Graffian follicles, Sertoli cells, Leydig cells

B
Graffian follicles, Sertoli cells and Seminiferous tubules

C
Graffian follicles, Leydig's cells and Seminiferous tubules

D
Sertoli cells, Seminiferous tubules, Leydig cells

Solution

The human testis consists of several coiled seminiferous tubules that are lined with germ cells which form the male gamete spermatozoa.
The Sertoli cells are nutritive cells, that provide nutrition to the growing sperms. They also secrete the hormone inhibin
The Leydig cells are another type of cells that are found in the testis that is responsible for the secretion of the testosterone and other male androgens.
So, the correct option is 'Sertoli cells, Seminiferous tubules, Leydig cell'
Question 5
1 / -0

Release of seminal fluid in the vagina of female is?

A
Ejaculation

B
Implantation

C
Insemination

D
Copulation

Solution

Insemination is the process of release of seminal fluid in the vagina of the female. If the insemination is done artificially then it is known as artificial insemination.
Ejaculation is the release of seminal fluid from the penis pf male.
Implantation is the fixing of the blastocyst on the uterine wall.
Copulation is the act of mating between the male and female.
So, the correct option is 'Insemination'
Question 6
1 / -0

Bartholin's glands are situated

A
On the side of head of some amphibians

B
At the reduced tail end of birds

C
On either side of vagina in humans

D
On either side of vas deferens in humans
Solution
Correct option: C
Explanation:
Bartholin's glands are compound adrenaline glands and have the shape of a pea.
They are homologous to the bulbourethral gland of the male.
It is present on either side of the vagina.
They have the function of secreting fluids for lubrication during sexual intercourse.
Hence, Bartholin's glands are situated "on either side of the vagina in humans".
Question 7
1 / -0

Which one is not associated with gametogenesis?

A
Formation of ova

B
Formation of spermatids

C
Release of ova

D
Change of spermatid to spermatozoa

Solution

Gametogenesis is the process of formation of gametes. In males, it is known as spermatogenesis which is the formation of spermatozoa and in females, it is known as oogenesis which is the formation of ova.
Spermiogenesis is a process which represents the change of spermatids to spermatozoa.
Here ovulation which is the release of the ovum from the ovary is not associated with gametogenesis. Hence, option c is correct.
So, the correct option is ' Release of ova'
Question 8
1 / -0

Function of sertoli cells is to

A
Nourish sperms

B
Form the sperms

C
Help in fertilization

D
Synthesis of hormones

Solution

Sertoli cells are also known as the 'nurse' or 'mother' cell as they nourish the sperms during the process of spermatogenesis.
These are a part of the seminiferous tubules.
The Sertoli cells are acted upon by the FSH hormone and they have FSH receptors on them.
So, the correct option is 'Nourish sperm'
Question 9
1 / -0

Which of the following process occurs first in embryo?

A
Neurogenesis

B
Notogenesis

C
Hepatogenesis

D
Cardiogenesis

Solution

During gastrulation, the morphogenetic movements take place. These morphogenetic movements leads to the formation of ectoderm. The ectoderm is the outermost germ layer. It invaginates on the inside and gives rise to the neural tube and thus the process of neurogenesis takes place first.
So, the correct option is 'Neurogenesis'
Question 10
1 / -0

In insect egg, cleavage is?

A
Equal holoblastic

B
Unequal holoblastic

C
Meroblastic superficial

D
Meroblastic discoidal

Solution

In insects the yolk is concentrated in the center with the nucleus in a net-like structure thus they have centrolecithal eggs.
In insect, the cleavage is partial or incomplete i.e meroblastic and superficial in nature. The cytokinesis does not take place and thus results in a polynuclear type of egg cell.
So, the correct option is 'Meroblastic superficial'
