Natural selection operates on populations over many generations. Which of the following allows natural selection to occur?

A.
the old age of the individuals which causes them to die
B.
the desire and the advantage of a population to remain constant
C.
the unequal ability of individuals to survive and reproduce
D.
the abilty for populations to change quickly from one trait to the next

C. The unequal ability of individuals to survive and reproduce.

Explanation:

Not everyone has the same ability to reproduce and survive due to their traits. Some traits are advantageous, some are neutral, and others are disadvantageous. This causes natural selection to rule out individuals with disadvantageous traits, causing the population to change.

identify the dna change shown in the diagram and explain how that change can result in the increased genetic diversity often seen among siblings.

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).
