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.

d concave shape of wave rock

explanation:

the concave shape of wave rock is a very good evidence that supports the evolution of earth due to chemical weathering. if we talk about structure of   wave rock, studies have estimated that it is around 2.7 billion years old. it also serves as the foundation of evidence that it was the place where australian continent began to form.

how the structure of wave rock was created?

studies suggest that structure of wave rock was created when the surrounded area was started to weather due to which deposition of material started on the part of land which now contains wave rock.

the structure of wave rock is considered to be one of the best-known landforms in australia. at the height of around 15 cm, there can be found flared slopes which formulate the margins of hyden rock. it is now assumed by geologists that wave rock was created by subsurface water-induced weathering and not by glaciers, waves or wind.

due to deposition of material over the period of long time, the wave rock became tougher and tougher due to weathering from surrounding terrain. this makes it a physical evidence that supports   the evolution of earth due to chemical weathering.

hope it !

the correct answer is b
