PLEASE HELP!

1. Research has shown that if prescribed dose of an antibiotic is not taken completely, some bacteria might not killed and the disease might return. How does natural selection explain the phenomenon

2. Explain how the scientific theory of evolution is supported by molecular biology

3. Summarize some of the experiences or observations that influenced Darwin during his voyage on the Begale.

1. Mutation would cause Natural selection in bacteria.

2. Molecular study gave evidences of similarity and dissimilarity between organisms.

3. Darwin noticed diversity, finches and changes on earth.

Explanation:

1. During replication in bacteria there are chances that mutation had occurred. The mutation would cause genetic variation which would lead to natural selection. As due to mutation bacteria might get resistant to antibiotic say gene change in cell wall. There are chances that bacteria reside in biofilm that is deep seated and small amount would not be sufficient to penetrate and kill bacteria hence large dose will be required.

2. The DNA, RNA and protein sequences are compared to study the analogy and similarity between organism's or species gene. This give evidences of evolution.

3. Darwin on his voyage on the Beagle noticed that:

 The rainforests and other forests have large variety in flora and fauna.

The surface of earth has changed over a period of time, as an earthquake changed the sea level by 9 feet.

The finches have adapted to their environment according to the needs.

it's anything that aren't producers and consumers.

explanation:

you've got to be clear on what "this" is
