Principles of Natural Selection

(Provide an example for each principle. You may
use complete sentences or even a picture with a
brief bullet point to explain.)

1. Variations exist within
populations:

2. Variations are inherited:

3. Organisms produce more
offspring than can survive:

4. Individuals with variations best suited for the habitat survive
and reproduce:

5. A population will change over
time (over several
generations):

answer: - b cells

explanation: -

there are many types of white blood cells present in our body. one such class of white blood cells are the lymphocytes. the b cells belong to the lymphocyte class of wbcs. the b cells perform their action against the pathogen by producing specialised proteins called as antibodies. these antibodies are produced as and when the b cells encounter pathogens in response to the antigens present on the surface of the pathogen. these antibodies bind to the antigens present on the pathogen and then, target them for destruction by other cells of the immune system.

so, the b cells mediate their action by identifying the antigens present on the surface of the pathogens and then producing antibodies in return to mediate its effect.

Yes they are correct good day

Idk i think the answer choice is number 1
