If Tyler does not eat a diet that includes essential amino acids, his cells will not be able to build

Answer:

Option D, TT ´ tt

Explanation:

Allele for tallnes "T" is dominant over the recessive allele "t"

The genotype of a heterozygous tall offspring will be "Tt"

When a cross is carried out between "TT " and "tt" , the following offspring are produced -

T T

t Tt Tt

t Tt Tt

All the offspring have genotype "Tt" which is a heterogyzous allele pair.

Since "T" is dominant over "t", all the alleles would be heterozygous tall.

Thus, in order to produce 100 percent heterozygous tall offspring, the cross must be carried out between "TT" and "tt".

Option D is correct

Rivers that have developed over a long period of time are found in wide valleys with flat, low-lying bottoms. These valleys were created by the removal of rock and soil through the process of Erosion.

What is Erosion?

Earthen materials are worn away during erosion, a geological process in which they are moved by wind or water. Weathering, a related process that does not involve movement, dissolves or breaks down rock.

The geological process by which earthen elements are deposited, or built up, on a landform, is called deposition. Erosion is the opposite of deposition.

Erosion occurs when the water or glacier ice is murky, the wind is dusty, or both. The brown tint shows that soil and rock fragments are being transferred from one location to another while suspended in the fluid.

Therefore, Rivers that have developed over a long period of time are found in wide valleys with flat, low-lying bottoms. These valleys were created by the removal of rock and soil through the process of Erosion.

Answer;

D.more curves

Explanation;

-Deposition is the process of the eroded material being dropped that takes place when a river loses energy. The loss of the river energy is attributed by factors such as reduction in rainfall, increase in evaporation, friction close to river banks and shallow areas which leads to the speed of the river reducing and thus the energy reduces. Deposition process would make a river change in more curves.
