NEET Biology Strategies for Enhancement in Food Production MCQs Set 04

Answer: (d) Rhinoceros

Explanation:
1. Livestock are the animals which are raised for our profit.
2. It includes pig, buffalo, goat but not rhinoceros.

Answer: (c) Selection of breeds which are vulnerable to diseases

Explanation:
1. Dairy farm management is the management of animals for milk and its products for human consumption and it includes. – Improvement in quality of milk. – Selection of good breeds having high milk yielding potential. – Maintenance of quality and quantity of fodder.
2. Fodder should have all essential nutrients, vitamins, minerals which ultimately improves the yield and quality of milk.

Answer: (b) Dairying

Explanation:
1. Dairying is the management of animals for milk and its products for human consumption.
2. Poultry is the class of domesticated fowl used for food and for their eggs.
3. Apiculture is the maintenance of hives of honeybees for the production of honey.
4. Fisheries is an industry devoted to the catching, processing and selling of fish, shellfish or other aquatic animals.

Answer: (d) Both (1) & (2)

Explanation:
1. A good breed of cattle means it should have all the desirable qualities to produce high yield and quality products.
2. For this it should have high yielding potential and resistance to diseases.
3. Good amount of water and food should be consumed.

Answer: (a) Animal Breeding

Explanation:
1. Feeding– To give food or supply with nourishment.
2. Weeding– Removal of unwanted plants.
3. Heeding– To pay attention to, listen to and consider.

Answer: (a) Breed

Explanation:
1. Variety– Varieties are usually the result of selective breeding and diverge from the parent species or sub-species in relatively minor ways.
2. Race– Races may be distinct phenotypic populations within the same.
3. Species– Largest group of organisms capable of interbreeding and producing fertile offspring.

Answer: (d) Increases homozygosity

Explanation:
1. Inbreeding increases homozygosity thus it is necessary to evolve pureline in any animal.
2. It involves accumulation of desired genes and removal of undesired genes which ultimately improves the breed.

Answer: (d) In-breeding

Explanation:
1. In this superior males are mated with superior females of same breed which gives superior progeny thus increasing homozygosity and evolving pure line in any animal.
2. Outbreeding involves mating of unrelated animals with no common ancestors upto 4-6 generation of same breed (out crossing) or breeding between different breeds (Cross-breeding).
3. Both types of out-breeding does not evolve pureline in any animal.

Answer: (a) Interspecific hybridization, obtained by crossing male donkey and female horse

Explanation:
1. Interspecific hybridization means breeding male and female of two different species.
2. Here donkey and horse are two different species forming a hybrid.

Answer: (d) All of these

Explanation:
1. Artificial insemination is injection of semen collected from male chosen as parent into reproductive tract of selected female by the breeder.

Answer: (b) Artificial insemination

Explanation:
1. Animal breeding – It is the normal breeding of animals to improve the breed.
2. MOET – (Multiple Ovulation Embryo Transfer): Involves administration of homones, with FSH-like activity, to induce follicular maturation and superovulation.
3. The fertilized eggs are then recovered non-surgically at 8-32 cells stage and transferred to surrogate mothers.

Answer: (d) Beeswax

Explanation:
1. Beeswax is secreted by abdominal wax glands of worker bees.
2. It acts as an excellent support for moisturisers and has an irritation potential of zero.
3. Honey has a medicinal value.
4. Oil– Mostly extracted from fishes.

Answer: (c) Fish

Explanation:
1. White revolution – Milk Silver revolution – Egg Green revolution – Wheat.

Answer: (d) Both (1) & (3)

Explanation:
1. Separation of infected birds from the flock of undiseased ones.
2. Culling– Segregating organisms from a group.
3. In bird flu infected ones are segregated from non-infected ones.

Answer: (c) Both egg and meat production

Explanation:
1. Feed should be nutrient rich for both egg and meat production.

Answer: (b) Coccidiosis

Explanation:
1. Fowl Cholera– Pathogen Pasteurella (bacteria).
2. Thrush– Fungal infection.
3. Ranikhet– Viral infection.

Answer: (d) Anthrax

Explanation:
1. Anthrax is a bacterial disease caused by Bacillus anthracis.

Answer: (c) Slow growth rate

Explanation:
1. Improved growth rate is an objective of animal breeding.

Answer: (b) Within the same breed having no common ancestors on either side of their pedigree upto 4-6 generations are mated

Explanation:
1. Option (1) Defines inbreeding Option (3) Defines cross-breeding Option (4) Defines interspecific hybridisation.

Answer: (c) Inbreeding helps in accumulation of deleterious alleles and elimination of desirable alleles

Explanation:
1. Inbreeding helps in accumulation of desirable alleles and elimination of deleterious alleles.

Answer: (d) Both (1) & (2)

Explanation:
1. Interspecific hybridisation is breeding of male and female of two different species.

Answer: (d) FSH

Explanation:
1. Follicle stimulating hormone– Stimulates the formation of follicle.
2. Estrogen– Causes proliferation of endometrium.
3. Progesterone– Functions in maintaining endometrium.
4. Testosterone– Male hormone- development of sperm.
