  1. Bioremediation

  2. Biomagnification

  3. Eutrophication

  4. Bioaccumulation
Reveal answer Fill a bubble to check yourself
A Correct answer
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.

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
Reveal answer Fill a bubble to check yourself
B Correct answer
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 

  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
Reveal answer Fill a bubble to check yourself
B Correct answer
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'
