B) rejection response

Answer : The correct answer for the blank is- C) autoimmune response.

When the immune system of the body fails to recognize "self" that is its own body tissue/own antigens, it produces antibodies against it.  


Due to this, the body's own cells, tissues, or organs are targeted, which cause inflammation and damage to the body. This condition develops as autoimmune response.

The answer is c an auto immune response

Which of the following statements is an accurate combination of postulates 1 and 2 of natural selection?Heritable variation exists for traits among individuals in a population.
Drug resistance exists among all individuals in a population.
Heritable variation does not exist among individuals in a population.
Environmental variation exists for traits among individuals in a population.

Answers

Answer:

Heritable variation exists for traits among individuals in a population.

Explanation:

According to Darwin's theory of evolution, natural selection is the main evolutionary mechanism. Darwin explains that organisms that have heritable traits that help them survive and reproduce, will be favorable by natural selection. Those favorable traits will enable organism to better adapt to their environment and to pass more genes on to the next generation (offspring).

Organisms adapt to their environment by changing their behavior, structural traits or physiology as a response to environmental change, so that they become well suited to it.
