The theory of states that organisms that are better suited for their environment will survive and reproduce, while those that are poorly suited for their environment will die off. a.) evolution by natural selection b.) genetic mutation c.) survivalism d.) behavioral genetics

A) evolution of natural selection

a.) evolution by natural selection.

Explanation:

According to the theory of natural selection, organisms which are better suited for their surrounding environment have higher chances to survive and reproduce as compare to organisms which are poorly suited for their surrounding environment.

Darwin gave theory of natural selection and stated that all living organisms show variations, which are essential for evolution of a new species. Hence, it is known as theory of evolution by natural selection.

prokaryotic cells do not have a nucleus in which the dna is stored in, it floats freely inside the cell.

eukaryote cells do have a nucleus in which the dna is stored in.

volcanoes (an event in the geosphere) release a large amount of particulate matter into the atmosphere. these particles serve as nuclei for the formation of water droplets (hydrosphere). rainfall (hydrosphere) often increases following an eruption, stimulating plant growth (biosphere).
