The second blank can be filled with designate their area as a national park. Designation of the areas as a national park is one of the methods of conserving animals, like a tiger.

Answer:
(A) Bioaccumulation
Explanation:
When the concentration of certain substances in the bodies of the organisms of various trophic levels keeps on increasing as they pass through the food chain, the process is called bioaccumulation or biomagnification.
Most of the organic non-biodegradable pollutants/chemicals exhibit bioaccumulation. Being insoluble in water, these chemicals are accumulated in the fat tissues of the organisms.
As the predator feeds on the prey having a non-biodegradable chemical in its tissues, the chemical enters the body of the predator.
As these chemicals pass through the food chain, there is a gradual increase in their concentration stored in the living tissues of the organisms. Therefore, the top consumers exhibit maximum bioaccumulation of contaminants in a food chain.
I think that it’s c but I could be wrong!
Answer:
The correct answer is reciprocity or pairing of the bases.
Explanation:
The fact that bases are reciprocal to one another (thymine and adenine, cytosine and guanine) means that the same information contained in one strand is also found in the other one. This led to the fact that the DNA molecule is the one that carries genetic information.
