Consider statements about animal husbandry: 1. Dairy farming involves the rearing of milk-producing animals. 2. Poultry farming involves the rearing of birds for meat and eggs. 3. Apiculture involves the rearing of silkworms. Which are correct? MCQ with Answer and Explanation

Consider statements about animal husbandry: 1. Dairy farming involves the rearing of milk-producing animals. 2. Poultry farming involves the rearing of birds for meat and eggs. 3. Apiculture involves the rearing of silkworms. Which are correct?
A. 1, 2 and 3
B. 1 and 2 only
C. 2 and 3 only
D. 1 and 3 only
Answer: Option B
Solution (By JKSSB Mock Tests)
Dairy farming is the business of breeding, raising, and managing dairy animals (like cows and buffaloes) for the production of milk and milk products. Poultry farming involves the commercial raising of domesticated birds (like chickens, ducks, and turkeys) for the production of meat and eggs. Apiculture is the scientific rearing of honeybees (Apis species) for the production of honey, beeswax, and other hive products; silkworm rearing is sericulture. Thus, statements 1 and 2 are correct.

Question #1
Which of the following eras is known as the 'Age of Reptiles'?
A. Paleozoic
B. Mesozoic
C. Proterozoic
D. Cenozoic

Correct Answer: Option B


Explanation:
The Mesozoic era (about 250-65 million years ago) is called the 'Age of Reptiles' or 'Age of Dinosaurs' because reptiles, especially dinosaurs, dominated terrestrial ecosystems. It is divided into Triassic, Jurassic, and Cretaceous periods. The Cenozoic is the 'Age of Mammals', the Paleozoic saw the rise of fishes and amphibians, and the Proterozoic is earlier.

Question #2
Which hormone is secreted by the anterior pituitary and stimulates growth of bones and tissues?
A. Follicle Stimulating Hormone (FSH)
B. Adrenocorticotropic Hormone (ACTH)
C. Thyroid Stimulating Hormone (TSH)
D. Growth Hormone (GH)

Correct Answer: Option D


Explanation:
Growth Hormone (GH), also known as somatotropin, is secreted by the anterior pituitary gland. It stimulates growth, cell reproduction, and cell regeneration, particularly in bones and skeletal muscle. Overproduction in childhood leads to gigantism, while underproduction leads to pituitary dwarfism. TSH, ACTH, and FSH are other anterior pituitary hormones with different target organs.

Question #3
In the male reproductive system, the spermatozoa are stored and mature in the:
A. Vas deferens
B. Epididymis
C. Prostate gland
D. Seminal vesicles

Correct Answer: Option B


Explanation:
The epididymis is a coiled tube on the posterior surface of the testis where spermatozoa undergo maturation and are stored until ejaculation. Sperm acquire motility here. Seminal vesicles and prostate gland secrete seminal fluid. Vas deferens transports sperm from epididymis to ejaculatory duct. Testes produce sperm and testosterone. Sperm maturation includes gaining ability to fertilize.
