Biology: CUET Mock Test - 2 - Question 1

Pollination through animals is ________

Detailed Solution for Biology: CUET Mock Test - 2 - Question 1

Zoophily is defined as pollination via animals. Insects are the most important animal pollinators. Birds, snails, bats, etc. also play an important role. Some lizards, lemurs, etc. also have proven to be important for pollination.

Biology: CUET Mock Test - 2 - Question 2

What do the Leydig cells secrete?

Detailed Solution for Biology: CUET Mock Test - 2 - Question 2

The areas on the exterior of the seminiferous tubules called interstitial spaces, contain small blood vessels and small clusters of big, polygonal cells called Leydig cells or interstitial cells. Leydig cells synthesize and secrete hormones (testicular) called androgens.

Biology: CUET Mock Test - 2 - Question 3

Among the following, which one is not included in the female external genitalia?

Detailed Solution for Biology: CUET Mock Test - 2 - Question 3

The female external genitalia include mons pubis, labia majora, labia minora, hymen and clitoris. The vagina is a fibro-muscular tube measuring 7.5-10cm in length, extending from the cervix of the uterus to the vestibule on the outer side.

Detailed Solution for Biology: CUET Mock Test - 2 - Question 5

Zoophilous flowers are often adapted to be pollinated by particular type of animals. Bees and butterflies pollinate the maximum number of flowering plants. The two common families pollinated by them are Asteraceae and Lamiaceae.

Biology: CUET Mock Test - 2 - Question 6

The growth, maintenance and functioning of secondary sex organs is maintained by the ____

Detailed Solution for Biology: CUET Mock Test - 2 - Question 6

The Correct Answer is A: testosterone

Testosterone is a hormone that plays a crucial role in the growth, maintenance, and functioning of secondary sex organs in males. It is primarily produced by the Leydig cells in the testes.

Testosterone is responsible for the development of male secondary sexual characteristics such as the growth of facial and body hair, deepening of the voice, and enlargement of the testes and penis during puberty. It also promotes the growth and maintenance of other reproductive structures such as the seminal vesicles, which produce seminal fluid, and the prostate gland.

Additionally, testosterone is involved in regulating sexual function and libido, sperm production, and the overall well-being and vitality of males. It influences the maintenance of muscle mass and bone density and plays a role in red blood cell production.

In summary, testosterone is essential for the growth, maintenance, and functioning of secondary sex organs and is vital for the overall development and reproductive health of males.

Biology: CUET Mock Test - 2 - Question 23

In olden days, _____ used to serve as an indicator of virginity.

Detailed Solution for Biology: CUET Mock Test - 2 - Question 23

The hymen, the thin membranous diaphragm at the vaginal orifice, is often torn during the first coitus (intercourse). Hymen maybe torn in other ways too, like sports, a disease, sudden jolt, etc. In some females, the hymen persists even after intercourse.

Detailed Solution for Biology: CUET Mock Test - 2 - Question 26

Syngamy is the process of fusion of a haploid male(n) and a haploid female(n) gamete. On fusion, the zygote or the egg formed is diploid(2n). Often this process is also known as fertilization.

Biology: CUET Mock Test - 2 - Question 27

Sweat and sebaceous glands are present in the ______

Detailed Solution for Biology: CUET Mock Test - 2 - Question 27

The labia majora (Large Lips) are fleshy folds of skin containing sweat and sebaceous glands, which extend down from the mons pubis and surround the vaginal opening.

Biology: CUET Mock Test - 2 - Question 29

The parthenogenesis is also called as ________

Detailed Solution for Biology: CUET Mock Test - 2 - Question 29

It is reproduction without fertilization. This means, the egg or ovum or the female gamete is not fertilized by the male gamete. The offspring hence born is haploid. Since there is no fertilization involved, it is called as virginal reproduction or virgin birth.

Biology: CUET Mock Test - 2 - Question 31

_______ are folds of mucous membrane.

Detailed Solution for Biology: CUET Mock Test - 2 - Question 31

The labia minora (Small Lips) are paired folds of mucous membrane under the labia majora and are devoid of hair and sweat glands but are rich in sebaceous glands.

Production of milk is called ______

Detailed Solution for Biology: CUET Mock Test - 2 - Question 32

Lactation occurs in females only when they’ve gestated a foetus. In some cases lactorrhea also know as galactorrhea is the occasional production of milk without any gestation.

Biology: CUET Mock Test - 2 - Question 33

Pollination by birds is ____

Detailed Solution for Biology: CUET Mock Test - 2 - Question 33

It is the mode of allogamy performed by birds. Only a few types of birds are specialised for this. They usually have small size and long beaks. Two common types of tropical pollinating birds are sun birds (Afro-Asia) and humming birds (America). Humming birds perform pollination while hovering over the flowers.

Biology: CUET Mock Test - 2 - Question 34

Tip of the glans penis is called _____

Detailed Solution for Biology: CUET Mock Test - 2 - Question 34

_______ equivalent to male scrotum.

Detailed Solution for Biology: CUET Mock Test - 2 - Question 35

The labia majora and labia minora are equivalent to the male scrotum and comprise of the vulva. The opening of the vagina is often covered partially by a membrane called hymen.

Biology: CUET Mock Test - 2 - Question 36

 ________ is retained throughout generations in parthenogenesis.

Detailed Solution for Biology: CUET Mock Test - 2 - Question 36

Since there is no fertilization, there is no crossing over of genes, hence the genotype is retained throughout generations in parthenogenesis. This means no variety in the population.

Biology: CUET Mock Test - 2 - Question 37

_____ provides nursery for moths.

Detailed Solution for Biology: CUET Mock Test - 2 - Question 37

A similar relationship exists between a species of moth and the plant Yucca where both species–moth and the plant–cannot complete their life cycles without each other. The moth deposits its eggs in the locule of the ovary and the flower, in turn, gets pollinated by the moth. The larvae of the moth come out of the eggs as the seeds start developing.

Biology: CUET Mock Test - 2 - Question 38

Where does syngamy occur?

Detailed Solution for Biology: CUET Mock Test - 2 - Question 38

Syngamy is the fusion of 2 haploid gametes to form a diploid zygote. This process of fusion happens internally inside the female body. Because of this, syngamy is also often known as internal fertilization.

Biology: CUET Mock Test - 2 - Question 39

Biology: CUET Mock Test - 2 - Question 40

What happens after the weaning of an infant?

Detailed Solution for Biology: CUET Mock Test - 2 - Question 40

After the weaning of an infant, the process of lactation stops and the process of apoptosis begins. This is the controlled death of the mammary cells which eventually brings back the glands to its puberty stage.
