The correct answer is C. Passive transport refers to the movement of substances such as ions across the cell membrane without the use of energy. Examples of such movement is diffusion, facilitated diffusion, osmosis and filtration. The opposite of passive transport is active transport and this needs energy to occur. Examples of active transport are proton pumps, exocytosis and endocytosis.
Answer:
The correct answer will be option-A.
Explanation:
Genetic variation is the difference in the DNA sequences of individuals in a population. Genetic recombination is the main reason for the diversity of organism on earth.
The genetic variation takes place during gamete formation by recombination of DNA sequences which takes place during prophase of meiosis I.
Since genetic variation involves changes in the coding segments of the DNA called genes which leads to mutations, therefore, flowering time does not influence the genetic variation and option-A is the correct answer
