Answer:
Option (3).
Explanation:
Mark recapture method is used for the estimation of population size of an area. The individuals are identified by some mark on them. The formula of mark recapture method is
N = M * C/ R
Here, N is the number of the individuals, M is the individuals are marked and captured, C is the individual captured again with mark or non mark and R is recaptured marked individual.
The individual with 200 population, 20 are marked for the first time represent the large population size.
Thus, the correct answer is option (3).
Answer:
The tRNA is released from the E site of the ribosome and the elongation process finishes while the termination process starts.
Explanation:
When the translocation process is finished the tRNA that is in the E site of the ribosome is released and the A site of the ribosome reads a stop codon in the mRNA in order to finish the elongation process and start with the termination process. In the termination process a termination factor joins the stop codon, the ribosomal subunits split apart, the protein and the tRNA dissociate from one another and the tARN is not in the P site of the ribosome anymore.
Answer:
Option C
Explanation:
Option A is incorrect as mutations may be detrimental to the organism and are not always beneficial. Option B is incorrect as there are instances where mutations may enable organisms to be better adapted to the environment. Option D is incorrect as genotypes are not selected for or selected against by environmental pressures, it is only the phenotype (exhibitable/ visible traits) that can be selected for or against, hence option C is the answer.
