Answer:
The correct answer is option B. favorable change in DNA of the insect.
Explanation:
At the point when a pesticide is first utilized, a little extent of the pest population may survive to introduction to the material because of their particular hereditary or genetic makeup. These surviving individuals pass along the gene resistance to particular insecticide or pesticide to next generation.
Upon introduction to pesticides, insects that don't have the resistance die eventually, in this manner permitting the insects with the resistance genes to endure and reproduce,creates more resistance insects.
Thus, the correct answer is option B. favorable change in DNA of the insect.
Answer: What is expected to happen is that the secondary immune system acts immediately against the virus.
Explanation:
When a virus first enters our body, in order to defend itself, the body must first recognize what the antigen is in order to fight it through <u>antibodies</u>. Once it does it will keep a memory of it that it can use if this virus enters the body again. <u>This will be done through the secondary immune system</u>.
As the body already recognizes the antigen, it knows how to fight it immediately, generating a thousand times the amount of antibodies generated the first time.
Thanks to its memory cells, the virus will remain much less time in the body.
I recall that Professor Kwang had observed amoebas that had cannibalized bacteria cells. The bacteria were slaughtering the amoebas, but somehow some survived. This particular group of amoebas contained bacteria that thrived inside it. Hence the name, endosymbiosis. However, this lucky group and it's offspring could not survive without bacteria.
Biology is the study of life so a Biologist would study biology: the study of life and living things.
