Answer: Option A. -> True
:
A
Foot and mouth disease, hemorrhagic septicemia and anthrax are contagious diseases. So, if symptoms appear in a single animal, all the animals in the farm have to be culled and their products have to be destroyed.

Answer: Option C. -> Heterozygosity
:
C
The increase in the level of production traits due to crossing is called hybrid vigour or heterosis. Hybrid vigour is the increased vigour of the offspring over their both parents. Such offsprings (hybrids) are obtained between two genetically different pureline varieties (parents).

Answer: Option B. -> Hardening
:
B
The final stage in tissue culture programme before the new plants are taken out for cultivation in the fields is known as hardening. Through this process, the newly generated plants are made to get accustomed to the harsh conditions in vivo.
Micropropagation is the practice of rapidly multiplying stock plant material to produce a large number of progeny plants
Organogenesis is the development of adventitious organs or primordia from undifferentiated cell mass in tissue culture by the process of differentiation.
Embryogenesis is the process of initiation and development of an embryo from a zygote

Answer: Option B. -> Goat
:
B
Pashmina is a fine type of cashmere wool. It is obtained from Kashmiri goat. This wool can be used tomake pashmina scarf, wrap, stole or cashmere blanket.

Answer: Option B. -> Single Cell Protein
:
B
Single Cell protein (SCP) refers to edible unicellular microorganisms. The protein extract from cultures of algae, yeasts, fungi or bacteria may be used as an ingredient or a substitute for protein-rich food, and is suitable for human consumption or as animal feed.

Answer: Option A. -> Apiculture – Honeybee
:
A
Apiculture is the rearing of bee or bee keeping for the production of honey and wax.
Sericulture is the production of silk and the rearing of silkworms.
Piscicultureinvolves raising fish commercially in tanks or enclosures, usually for food.
Vermiculture involves the cultivation of earthworms, especially in order to use them to convert organic waste into fertilizer.

Answer: Option C. -> Bio-fortification
:
C
Biofortification is the process by which the nutritional quality of food crops is improved through agronomic practices, conventional plant breeding, or modern biotechnology. Crop protection is the science and practice of managing plant diseases, weeds and other pests. Bioremediation is a waste management technique that involves the use of organisms to remove or neutralize pollutants.

Answer: Option D. -> Ranikhet disease
:
D
Ranikhet disease is a common viral disease in poultry. Foot and mouth disease is a common viral disease in cattles. Anthrax is also found in cattles. Pebrine is a protozoan disease of silkworm.

Answer: Option C. -> Artificial breeding
:
C
Artificial breeding - Here no mating occurs and the breeding is controlled by many different artificial methods.
The different artificial methods are
Artificial insemination - the process of collecting semen from a superior male animal and manually depositing it into the reproductive tract of a high yielding female.
MOET - Multiple Ovulation Embryo Transfer. Multiple fertilized embryos are obtained form a single cow and placed in multiple surrogate mothers.

Answer: Option C. -> Black rot of crucifers
:
C
Black rot is caused by the bacterium Xanthomonas campestris and it is considered the most serious disease of crucifer crops worldwide. Smut of Bajra, rust of wheat, red rot of sugarcane are fungal dieases.
