Which area of the earth's crust would be expected to be thickest?under the Atlantic ocean
in the Rocky Mountains
under the Missouri River
inside the Grand Canyon

Answers

Answer 1
Answer:

The thickest part of the earth’s crust is under mountains. Whenever there is a volcanic eruption, more material is poured out on the earth’s surface from under the crust, so as the years pass the earth’s crust is increasing slowly.


The area of Rocky Mountains is where the earth’s crust would be expected to be thickest.


Answer: In the Rocky Mountains.


I hope this helps, Regards.
Answer 2
Answer: The thickest part of the earth's crust is under mountains. Whenever there is a volcanic eruption, more material is poured out on the earth's surface from under the crust, so in that sense yes, the earth's crust is increasing slowly.
So under the mountains

A patient has diabetes, a disease that causes high blood sugar levels. Which macromolecule will a dietician monitor most closely in a patient that has the disease

Answers

The answer is carbohydrate. The carbohydrate is consists of monosaccharides which includes sugar(glucose). So the carbohydrate will be a best dietician monitor.

The macromolecule that a dietician should monitor closely in a patient is : Carbohydrate

What are macromolecules ?

Macromolecules are molecules which are consisted of a large number of atoms. The macromolecule that the dietician should monitor closely is carbohydrates because carbohydrate consists of monosaccharides which includes sugar(glucose).

Hence we can conclude that The macromolecule that a dietician should monitor closely in a patient is : Carbohydrate

Different mRNA molecules can have poly-A tails of different lengths. Considering the purpose of adding the poly-A tail (from the previous question), why are some tails longer than others?

Answers

Answer:  Then the longer it is, the more it protects against degradation. Proteins that are needed over a long period of time come from a long tailed mRNA.

Explanation:

Messenger RNA (mRNA) is the ribonucleic acid that transfers the genetic code from the DNA of the cell nucleus to a ribosome in the cytoplasm. It determines the order in which the amino acids in a protein will bind and acts as a template or pattern for the synthesis of that protein.

Messenger RNA is synthesized in the cell nucleus in eukaryotes from the process called DNA transcription. In most cases, once this messenger RNA has been synthesized, it must be matured (RNA maturation). This involves the removal of intercalary sequences called non-coding introns from the protein to be synthesized. Then, the addition of a structure called CAP to the 5' end, which is a modified guanine nucleotide needed for the normal process of DNA transplantation and maintaining its stability. This is critical for proper recognition and access of the ribosome.  Also, polyadenylation which is the addition of the sequence called Poly-A to the 3' end. The Poly-A sequence is made up of several adenine molecules and is located at about 20-30 bp towards the tail (AAPAA sequence) or polyadenylation signal, which protects the end of the mRNA. The polyadenylation helps to increase the period of the message, so that the transcription lasts longer in the cell and therefore more protein is translated and produced.

This mature messenger RNA is transferred to the cell's cytoplasm, in the case of eukaryotes, through pores in the nuclear membrane.  The messenger RNA in the cytoplasm is coupled to the ribosomes, which are the machinery in charge of protein synthesis.  However, after a certain amount of time the mRNA is degraded into its component nucleotides, usually with the help of ribonucleases. So, an mRNA with a short tail will have a shorter lifespan.

Then, proteins that are needed over a long period of time come from a long tailed mRNA. And proteins that are briefly nedded come from a short tailed mRNA. This is because, as explained, the Poly-A tail serves to protect the mRNA molecule from degradation. So, then the longer it is, the more it protects against degradation.

Which term refers to a change in one species that results from a change in another species that it interacts with?

Answers

The answer is coevolution.

Coevolution is a change in one species that results from a change in another species that it interacts with. For example, some species of orchid and African moth coevolved. That was a consequence of African moths' dependence on flower nectar and the orchids' dependence on moths' help in pollination. This two species coevolved, therefore the orchids have deep flowers while African moths have long proboscides.

Answer:

Interdependence

Coevolution

What role does pyruvic acid play in cellular respiration?

Answers

Pyruvic acid or pyruvate is a product of broken-down glucose during glycolysis. It is an ingredient in cellular respiration processes including the Kreb's cycle where it is transformed into lactate. It is also used to supply and distribute oxygen to cells through the citric acid cycle.
