Answer: Granite.

Explanation:

Granite rock is a common type of felsic intrusive igneous rock that is granular and phaneritic in texture. Granites can be predominantly white, pink, or grey in colour, depending on their mineralogy.

Granite is nearly always massive (i.e., lacking any internal structures), hard, and tough. Granite has poor primary permeability, but strong secondary permeability through cracks and fractures if they are present.

Fundamental to understanding mountain geology is the nature of minerals and rocks, for the mountains are made out of rocks, and the rocks are made out of minerals. The simplest, most widely known and distributed mineral is quartz (silicon dioxide), which is made up of the elements silicon and oxygen.

Answer:

They maintain their body temperature higher than their environment by some metabolic processes like contraction of muscles, friction produced by flow of blood etc. They have a higher basal metabolic rate, and also a greater capacity to increase their metabolic rate.

Are the layers of rock above and below the coal older or younger?

son4ous [18]

Answer:

The layer of the rock is older than the layer above it and younger than the layer below it.

Explanation:

According to the law of superposition, the layer which is above is always younger than the layer below it. This law is based on the very common fact that the older layer had to lay down first and then a new layer formed above it. This process is used to determine the relative age of the rocks.

miRNAs can control gene expression by what action?A. degrading proteins as soon as they are formedB. inhibiting the catalytic ac

levacccp [35]

Answer:

C) binding to mRNAs and degrading them or blocking their translation

Explanation:

miRNAs:

miRNAs is the abbreviation of MicroRNAs. These are the small noncoding RNAs of ∼22 nucleotides which can not code for peptides. miRNAs are responsible for gene expression regulation at the level of post transcription. They can do so by forming complementary base pairing with target mRNA and inhibiting their translation.

They silenced mRNA by the following processes:

(1) Cleavage of the mRNA strand into pieces,

(2) stopping mRNA from translation into proteins by ribosomes.

(3) Shortening of mRNA poly(A) tail and destabilizing it.
