Describe each type of mountain. Include the type of boundary where they are likely formed and characteristics of each. Folded Mountains: Fault-block Mountains:

Answers

Answer:

Folded mountains are all those originated by movements and collisions of the great plates that form the earth's crust. Fault-block mountains are those that appear from a break in the crust, a fact that causes the rock blocks to move up and down and form elevations.

Explanation:

The parallel movement of the earth's crust leads to the appearance of Folded Mountains. According to this theory, Folded Mountains originate from the collision between two tectonic plates. Some of these plates are huge and can support and carry entire continents. When two plates collide, the denser one gets under the other, and this causes the sediments deposited in the basin or geosyncline that separated them to fold up. The large folds formed in the compressed sediment can break apart and form mountains.  Fault-block Mountains are related to normal wide-angle faults that gradually decrease in dip with depth. Most of the Fault-block Mountains form in response to a large uplift.

C.

D.

Answers

Answer: C.

has different alleles on the chromosomes in a chromosome pair

Explanation:

Hetero means different.

A heterozygous condition is one in which the child inherits various eye-color genes from both biological parents. For that particular gene, a heterozygous genotype exists when there are two distinct versions. Thus, option C is correct.

What is the particular trait for heterozygous organism?

When two distinct alleles of a gene (one mutant allele and one wild-type allele) are present in a diploid organism's cells, that organism is said to be heterozygous at that particular gene locus.

Heterozygosity describes a particular genotype, since the cell or organism is referred to be a heterozygote just for the particular allele in question.

The heterozygote may, however, occasionally have a phenotype that is somewhere between the phenotypes of both homozygous parents.

Therefore, has different alleles on the chromosomes in a chromosome pair.
