Intraspecific competition drives natural selection because a. individuals that can survive despite limited resources and competition will reproduce at a higher rate. b. other species in the same environment may have advantageous adaptations to the environment. c. individuals that work with other individuals of their species will have a higher chance of finding food. d. similar species in different environments often develop similar structures to carry out similar functions.

The correct option is A.

Explanation:

Intraspecific competition refers to the type of competition in which living organisms belonging to the same specie compete for common limited resources. When the required resources that are needed to survive become scarce, then it is only the fittest organisms that will survive, these set of organisms usually found a way of adapting to the changes that occur in their environments and they usually go on to reproduce young ones that replace them. This process leads to evolution in which living organisms that possess the right traits are able to survive and reproduce in a particular habitat.  

the answer is z.

the human body has five levels of organization. level 1: cells. cells are the basic units of life and form the first level of organization. cells in the human body have specific functions. examples include nerve cells, blood cells, liver cells, and so on.
