In fish farming, 'induced breeding' is commonly achieved by injecting: MCQ with Answer and Explanation

In fish farming, 'induced breeding' is commonly achieved by injecting:
A. Pituitary extract containing gonadotropins
B. Adrenaline
C. Insulin
D. Thyroxine
Answer: Option A
Solution (By JKSSB Mock Tests)
In pisciculture, induced breeding is carried out by injecting fish with pituitary gland extract from donor fish containing gonadotropic hormones (FSH and LH), which stimulate spawning. This allows controlled production of fish seed. Hypophysation is the technique used in Indian major carps. Insulin and thyroxine are not involved in reproduction. Adrenaline is a stress hormone.

Question #1
The disorder caused by an extra X chromosome in males (XXY) is:
A. Cri du chat syndrome
B. Klinefelter syndrome
C. Turner syndrome
D. Down syndrome

Correct Answer: Option B


Explanation:
Klinefelter syndrome (47,XXY) is a sex chromosome aneuploidy causing male hypogonadism, tall stature, gynecomastia, and infertility. Turner syndrome (45,X) affects females. Down syndrome is trisomy 21. Cri du chat is deletion in chromosome 5. Nondisjunction during meiosis leads to these aneuploidies.

Question #2
Consider the following statements about antibodies:
1. They are produced by T-lymphocytes.
2. They are also called immunoglobulins.
3. They specifically bind to antigens.
Which of the above is/are correct?
A. 1 and 3 only
B. 1 and 2 only
C. 2 and 3 only
D. 1, 2, and 3

Correct Answer: Option C


Explanation:
Antibodies are produced by B-lymphocytes (plasma cells), not T-cells. They are immunoglobulins that bind specific antigens. Thus, 2 and 3 are correct.

Question #3
Which of the following is a unique feature of plant cells compared to animal cells?
A. Presence of Golgi apparatus
B. Presence of plastids
C. Presence of ribosomes
D. Presence of mitochondria

Correct Answer: Option B


Explanation:
Plastids (chloroplasts, chromoplasts, leucoplasts) are unique to plant cells and some protists. They are involved in photosynthesis, storage, and imparting color. Mitochondria, Golgi apparatus, and ribosomes are present in both plant and animal cells. The cell wall and large central vacuole are also distinguishing features of plant cells.
