Answer:

The process whereby organisms better adapted to their environment tend to survive and produce more offspring. The theory of its action was first fully expounded by Charles Darwin, and it is now regarded as be the main process that brings about evolution.

Four conditions are needed for natural selection to occur: reproduction, heredity, variation in fitness or organisms, variation in individual characters among members of the population. If they are met, natural selection automatically results.

lbvjy [14]

Answer:

Starch and water will be the best negative control

Explanation:

Negative control sample is a sample that will not give change in an experiment.
