Answer:
c
Explanation:
Gas exchange. Gas exchange occurs as a result of respiration, when carbon dioxide is excreted and oxygen taken up, and photosynthesis, when oxygen is excreted and carbon dioxide is taken up. The rate of gas exchange is affected by: the area available for diffusion.
Answer:
Option A, Start the reaction by absorbing light energy
Explanation:
Chlorophyll is a green color pigment in plant that helps in entrapping sunlight. Being green in color, it absorbs the blue and red light and reflects the green light. The molecules of chlorophyll gains energy from sunlight and then jumps to higher energy levels by the process known as photo excitation. These excited molecules get ionized to further initiate the process of photosynthesis.
Hence, option A is correct.

<span>Cilia and flagella are made up of microtubules covered by
plasma membrane and they projection from the cell. Thus, cilia are flagella are
motile and designed to move substances over or around the cell and they can as
well move the cell itself. In eukaryotes, they are conserved in their polypeptide
composition, structure and function as motile and sensory organelles.</span>
I think it’s A a virus can grow and develop
The correct answer is option A, They will have a large amount of genetic variation
Reason -
The transfer of pollens from the flower of one plant to the flower of another plant, is termed as cross pollination.
During cross pollination, two major instances can occur –
a) The transferred pollens may be of wild nature due to which fertilization of eggs do not take place
.
b) The transferred pollens can fuse with the egg of the parent plant and results into offspring’s that shall carry the characteristics of both the genetically distinct plants thereby producing hybrid plants.
