nekit [7.7K]

Answer:

The answer is E.

Explanation:

In vivo or in vitro evolution (Directed Evolution) is a technique used by genetic scientists to push the change in nucleic acids or proteins in a specific direction to get the end results that they want.

And high-fidelity polymerase is used to get a replica of the target DNA that has less errors.

So the situation given in the question where researchers use a higher-fidelity DNA polymerase in vitro evolution, the mutation rate would most likely be lower because of the high-fidelity DNA polymerase.

I hope this answer helps.

Around the year 1800, it was discovered that fossils are arranged in comparable patterns within the layers of the Earth. Name 3

frez [133]

Answer:

Study of comparative anatomy emerged in the 18th century and led to establishment of relationship between species based on the common traits

Explanation:

The three major events that occurred after this discovery are –

a) Discovery of the fact that the age of earth is much higher than the age of earth as found in previous theories of continental drift theory

b) The age of the oldest fossils was determined and based on that relative age of all species (as found in fossils) was determined.

c) The determination of age of fossil helped to find the gaps in the evolutionary tree and hence provoked search of these missing species.

The study of comparative anatomy started somewhere around 1800 when George Cuvier emerged as father of comparative anatomy

Based on comparative anatomy study, scientists such as Buffon and Lamarck worked on establishing relationship between species based on the common traits shared between them

What are examples of pesticide

musickatia [10]

There are 6 common types of pesticide that are recognized and seen quite often:

1. Insecticides which are mainly used to kill insects, ticks, and mites.

3. Fungicides which are mainly used to kill mildew and other fungi.
4. Rodenticides which are mainly used to kill mice, rats, and other rodents.
5. Disinfectants which are mainly used to kill bacteria and mold.
6. Wood Preservatives which mainly protects wood from fungus and insects invading it's system.
