True
DNA are cells that carry genetic codes and are passed down through generations of offspring. New cells can only arise from existing cells!
<span>The two stages of photosynthesis. Photosynthesistakes place in two stages: light-dependent reactions and the Calvin cycle (light-independent reactions). Light-dependent reactions, which take place in the thylakoid membrane, use light energy to make ATP and NADPH.

Answer:
Explanation:
The degerming is the act of handwashing. In this process, the microbes are removed by scrubbing the hands with a disinfectant usually a chemical, sterilizer, soap or detergent. This process will help in removing the microbes from the skin. It is a mechanical process of removing the germs or microbes without killing them.
This process provides a temporary protection from microbes.
The correct answers are:
b. Human influenza a virus evolves escape variants, resulting in a distinctive cactus-shaped phylogeny.
All types of Human influenza viruses evolve to escape immunity induced by prior infections and vaccinations.
c. Measles experiences strong selection for escape variants, resulting in a phylogeny similar to a nonpathogenic species.
As a result of measles infection, specific antibody and CD4 and CD8 T cell responses are generated and contribute to virus clearance and protection from reinfection.
