Answer:

Option (3)

Explanation:

The continental crust is usually thick because it has an average thickness of about 35-40 km. In the high mountain ranges, it is the thickest, forming about 80 km on an average. These are formed when two continental plates form a sandwich pattern by sharing a convergent type of plate boundary.

For example, the thickest part of the crust is the Mt. Everest which lies in the great Himalayan range, which has started to form about 50 million years back. It is geologically the most recent mountain range.

The older mountains are continuously eroded in the geological past, as a result of which the height of the mountains is affected.

Thus, the correct answer is option (3).

The thickest part of the crust occurs in the young mountain ranges.

Further Explanation:

The earth's crust is made up of different types of rocks, such as metamorphic, sedimentary and igneous rocks. It is supported by the mantle. The crust is rigid, thin and mainly composed of rocks. The lithosphere is consists of crust and mantle. When the distortions of Earth's Crust occur, the alternate sides of a crust experience shear stress and continue till the internal rigidity surpasses. The fault line is formed with sudden shaking that releases mass-energy that separates the plates into two splits. The crust is of two types:

Continental crust: It is the thickest part of the earth's crust that is mainly present beneath the mountain.
Oceanic crust: It is denser than continental crust. It is made up of diabase, gabbro, and basalt.

Predict the fur color of the offspring of a brown heterozygous rabbit and a white homozygous rabbit. Brown is dominant and white

fgiga [73]

Answer:

To predict the results of the offspring from a cross between brown heterozygous rabbit and a white homozygous rabbit, a punnet square can be drawn as follows:

b b

B Bb Bb

b bb bb

The results from the punnet square show that there is 2:2 ratio that the offspring will be brown coloured or white coloured. The genotype of the rabbits will either be heterozygous brown i.e Bb or homozygous white bb.

there is a 50% chance that the offspring will be brown rabbit and there is also a 50% chance that the offspring can be a white rabbit.

1. A mutation of a human gene blocks harmful viruses from infecting cells. How can the mutation be classified?

Yuri [45]

Answer:

It is a beneficial mutation.

Explanation: Mutations are permanent changes in the nucleotide sequence of a DNA. Mutations can beneficial, neutral and harmful or deleterious. When change in the nucleotide sequence of DNA a mutation enhances the effectiveness of a protein or improves the protein function, it is said to be beneficial. When a mutation causes the synthesis of a protein which have the same amino acid as the original protein and performs the same function as the original protein, it is said to be silent or neutral. When a mutation results in the synthesis of a protein with an altered amino acid sequence and a nonfunctional protein, it is said to be harmful.
