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

Explanation:
Capitulum (head) is characteristic of the Asteraceae family, where numerous small florets are arranged on a flattened disc. Raceme has flowers on pedicels along an elongated axis, spike sessile, umbel umbrella-like. Sunflower inflorescence is a capitulum.

Explanation:
Melanocyte-Stimulating Hormone (MSH) is a peptide hormone produced primarily by the intermediate lobe of the pituitary gland (pars intermedia), though in humans, this lobe is rudimentary and MSH is mainly derived from the cleavage of pro-opiomelanocortin (POMC) in the anterior lobe. Its primary function, especially in lower vertebrates like amphibians and reptiles, is to stimulate the melanocytes in the skin to produce and disperse melanin, the pigment responsible for skin, hair, and eye color, leading to darkening of the skin. In humans, its role in pigmentation is less significant.

Explanation:
Melanin, produced by melanocytes in the epidermis, is the primary pigment determining skin, hair, and eye color. It absorbs UV radiation, protecting DNA from damage. Keratin is a structural protein in hair and nails, collagen provides connective tissue strength, elastin elasticity. Albinism results from melanin deficiency.
