  1. Meat

  2. Insulin

  3. Both A and B

  4. Fats

Show answer
Correct Option: B
Explanation:

Animal insulin is derived from cows and pigs. Until the 1980s, animal insulin was the only treatment for insulin dependent diabetes. These days the use of animal insulin has largely been replaced by human insulin and human analogue insulin, however, animal insulin is still available on prescription.

  1. Bioremediation

  2. Biomagnification

  3. Eutrophication

  4. Bioaccumulation

Show answer
Correct Option: A
Explanation:

Bioremediation is the use of living micro organisms to degrade the environmental contaminants into less toxic forms. It uses naturally occurring bacteria and fungi or plants to degrade or detoxify substances hazardous to human health and the environment.

  4. Both A and C

Show answer
Correct Option: D
Explanation:

Ethics means a branch of philosophy that deals with human conduct and how right or wrong an action or the motives behind an action may be. 
Environmental ethics and animal ethics should be strictly followed before when genetic engineering is been conducted as any technology should not harm the environment as well as animal life.

  1. Surgical procedure under appropriate anesthesia

  2. Research with professional standard

  3. Any animal can be used

  4. Both A and B

Show answer
Correct Option: D
Explanation:
Anesthesia enables a animals to tolerate surgical procedures that would otherwise inflict unbearable pain.
Bioscience community accepts that animals should be used for research only within an ethical framework.

Animal suffering during testing can be minimized by which of these principles of ethics of animal biotechnology?

  1. Reduction

  2. Refinement

  3. Replacement

  4. All of the above

Show answer
Correct Option: B
Explanation:

Refinement refers to methods that minimise the pain, suffering, distress or lasting harm that may be experienced by research animals, and which improve their welfare. 

Refinement applies to all aspects of animal use, from their housing and husbandry to the scientific procedures performed on them.

The transgenic animals are those which have 

zoology biotechnology and its applications transgenic animals transgenic organisms applications of biotechnology

  1. Foreign DNA in some of its cells

  2. Foreign DNA in all its cells

  3. Foreign DNA and RNA in some of its cells

  4. Foreign DNA and RNA in all its cells

Show answer
Correct Option: B
Explanation:
Transgenic animals are animals that have had a foreign gene deliberately inserted into their genome. Such animals are most commonly created by the micro-injection of DNA into the pronuclei of a fertilised egg which is subsequently implanted into the oviduct of a  surrogate mother.
So, the correct answer is 'Foreign DNA in all its cells'
