Animal husbandry and plant breeding programmes are the examples of

  1. Reverse evolution

  2. Artificial selection

  3. Mutation

  4. Natural selection


Correct Option: B
Explanation:
Animal husbandry and plant breeding programmes are the examples of artificial selection. The artificial selection is the modification of species by selective breeding. Animals or plants with desirable characteristics are interbred with the aim of altering the genotype and producing a new strain of the organism for a specific purpose. Traditional breeding techniques have been supplemented by more recent methods of genetic engineering, genetic testing and embryo manipulation. Sequencing of genomes of commercially important animals and plant species has enabled the inheritance of desired genes to be monitored directly by molecular methods.

So, the correct answer is 'Artificial selection'.

Animal husbandry deals with

  1. Breeding of farm animals

  2. Care and treatment of animals

Earliest animal domesticated by primitive man was 

  1. Goat

  2. Dog

  3. Horse

  4. Cat


Correct Option: B
Explanation:

Dogs are the earliest animals made as pets. The first potential evidence of dog domestication dates back to 30,000 B.C., in the form of a wolflike creature found in a cave in Belgium. Other evidence suggests dogs weren't domesticated until thousands of years later. Before they were pets, dogs helped human hunt and cats helped guard grain supplies by keeping rats and mice away. Eventually, people started to treat these animals more like pets. At present human-canine bonding is the mutually beneficial and dynamic relationship between human and dogs that is studied by psychologists, anthropologists and ethologists.

Cattle fed with spoilt hay of sweet clover which contains dicumarol ..........................

  1. Are healthier due to a good diet

  2. Catch infections easily

  3. May suffer vitamin K deficiency and prolonged bleeding

  4. May suffer from Beri-Beri due to deficiency of B vitamins


Correct Option: C
Explanation:

Sweet clover poisoning is caused when feeding moldy sweet-clover hay or silage that contains dicoumarol. Dicoumarol is a toxic compound that is produced through weathering of a normal component of sweet clover called coumarol. It is the dicoumarol that causes the sweet clover poisoning, preventing normal blood clotting and causing extensive hemorrhaging. When sweet clover becomes spoiled or is improperly cured the coumarol is converted to the toxic substance dicoumarol. This toxin interferes with the metabolism and synthesis of vitamin K. 

Vitamin K is essential for liver function, necessary to prevent the seepage of blood from the circulatory system and to establish blood clotting. Without vitamin K, the blood will not clot properly after an injury, and this is why sweet clover poisoning is also called sweet clover bleeding disease.

  • Animal agriculture is responsible for 20%-33% of all freshwater consumption in the world today. Animal agriculture is the leading cause of species extinction, ocean dead zones, water pollution, and habitat destruction. 
  • Animal agriculture contributes to species extinction in many ways. In addition to the monumental habitat destruction caused by clearing forests and converting land to grow feed crops and for animal grazing, predators and "competition" species are frequently targeted and hunted because of a perceived threat to livestock profits. 
  • The widespread use of pesticides, herbicides and chemical fertilizers used in the production of feed crops often interferes with the reproductive systems of animals and poison waterways. 
  • Animal agriculture is responsible for up to 91% of Amazon destruction. 

Therefore, the correct answer is option D.
