Answer:
A. sexual reproduction
Explanation:
Sexual reproduction produces a new combination of genes in the offspring that may better enable them to survive changes in the environment and assist in the survival of the species.
An organism that exhibits a head with sensory equipment and a brain probably also have receptors, which capture the stimuli of the environment and transform them into a nervous impulse, and organs of the senses that are the communication channels we have with the environment and thanks to them we understand and interpret the environment, they are: vision, hearing, smell, taste, and touch.
The situation is an exponential growth wherein an example is on population when as the population gets larger, it grows more quickly.
In ecology, a group of particular organisms which live in a community is called POPULATION.
For instance, all the number of lions which live in a community make up the population of lions in that community. Populations of different species of animals that are found in that area combine together to form the community.
