mRNA

Messenger RNA is used to copy and encode genetic information from DNA base pairs by forming complementary strand of RNA molecule from the nucleus of the cell to the cytoplasm.

tRNA

Transfer RNA reads sequence of nucleotide from messenger RNA and translate them into proteins or amino acids during proten synthesis.

Transcription

This is the first step in gene expression where information from DNA is copied into a complementary strand of RNA molecule using RNA polymerase enzyme.

Translation

Messenger RNA made from the process of transcription travels to the ribosomes in the cytoplasm where proteins are produced using transfer RNA to copy the information.

The use of DNA to make proteins.

Through gene expression (central dogma of biology), the DNA molecule carries information, a gene code, in form of base pairing sequences that are transcribed to RNA and further translated to functional proteins or amino acids.

the pupil opens and closes automatically in response to light what part of your nervous system controls this response
denis23 [38]

PNS controls this response


The portion of the system that's outside the brain and medulla spinals. Abbreviated PNS. The nerves within the PNS connect the central system (CNS) to sensory organs, like the attention and ear, and to alternative organs of the body, muscles, blood vessels, and glands.

Papillary response could be a physiological response that varies the scale of the pupil, via the optic and cranial nerve.

5. A dedicated earth science student using
const2013 [10]

Answer:

(2) 988.5 mb.

Explanation:

The air pressure descends as we ascend. In other words, they are inversely proportional.

The air pressure descends as we ascend the mountain because the air molecules that are above us in high altitudes are fewer than the number of air molecules that are above us in the base of the mountain. So, the exerted pressure of the molecules on ourselves is lower in high altitudes.

Due to the reason mentioned above, we can deduce that the only correct option is option number two since the other ones show increasing or the same pressure, which is not possible as we ascend.

When elements combine to form compounds what happens to the properties of the original elements?
exis [7]
The properties of the original elements are completely changed.

For example, in the compound called "iron(II) sulphide", it is composed of iron and sulphur, that are chemically combined together. The element iron is attracted to magnets. Meanwhile, iron(II) sulphide is not attracted to magnets. 

Another example is where sulphur has a yellow colour, but iron(II) sulphide has a brownish colour. As we can see, even the physical properties (colours) are completely different.

Therefore, the properties of the original elements are completely changed when they're combined into compounds.
