marusya05 [52]

The most characteristic feature of clastic  sedimentary rocks is "stratification".

<u>Answer:</u> Option A

<u>Explanation:</u>

"Stratification" is an essential characteristic of the sedimentary rocks take place in an igneous rock produced at the surface of the Earth naturally due to volcanic fragmental deposits and flows of lava. It defines the pattern in which sediment layers are layered over each other and may occur on a scale of hundreds of meters, even down to sub-millimeter.

It also results from variations in texture or composition during deposition. Delays in deposition may also permit for variations to the older deposits before coverage given by new sediments. This mechanism in sedimentary rocks change in both, the degree of prominence and in structure details.

Mashcka [7]

Answer:

monoallelic gene expression

Explanation:

<em>Monoallelic expression is a type of gene expression where only a copy out of the two copies of a gene is expressed and the other is silent. </em>

A gene is usually represented by two alleles representing alternate forms of the same character. Individuals inherit an allele each from their two parents for every gene within their genomes.

When only one of the alleles is expressed for a particular gene while the other allele remains silent, such phenomenon is referred to as monoallelic gene expression.
