  <span>Neutral mutations are neither harmful nor beneficial. 

Therefore, they are invisible to natural selection. (Since they neither improve nor worsen one individual's chances of survival and reproduction over another.) 

However neutral mutations can still spread into the population by just random replications and matings. This is called genetic drift. 

In other words, they are 'silent'. They are mutations that exist and propagate in populations, but seem to have no effect at all. 

The reason they can become important to evolution is that a day can come when they *do* have an effect. In other words, even though an individual mutation may have no immediate effect on survival or reproduction, a *combination* of neutral mutations may provide some new benefit or harm ... at which point natural selection *will* act on that combination.

Which type of RNA carries a genetic code from DNA to the ribosome?
Aliun [14]

Answer:

(A). mRNA.

Explanation:

During protein synthesis, information present in DNA as triplet codons gets transferred to mRNA molecule, by the process of transcription. The mRNA than gets transported to the cytosol, where it associates with ribosomes.

Ribosomes are known as protein factories of the cells as they provide platform for translation. During translation, information present in mRNA is used to translate polypeptide chain or protein as each codon codes for a specific amino acid.

Thus, the correct answer is option (A).

enzymes degrade proteins, lipids, and large carbohydrates to smaller building blocks in the digestive tract. why must these macr
Rom4ik [11]

Amino acids, which serve as the "building blocks" of proteins, are disassembled. These tiny molecules can be absorbed through the stomach wall after being released.

<h3>Describe how the macronutrients in your diet are digested and then put back together to form the cell structure.</h3>

The principal macromolecules, from which all life is derived, are macrounits in our diet. The smaller subunits of these macromolecules must be broken down in order to be released. The circulatory system carries the digestively released components to the body's cells. These subunits serve as the building blocks for the macromolecules required for cellular structure and function, which are then put together by cells.

Proteins, lipids, and carbohydrates are examples of macromolecules.

The fact that all three macromolecules are hydrocarbons means that the majority of their atoms are made up of hydrogen and carbon.

Nitrogen atoms are found in proteins and in lipids.

Carbon atoms make up carbohydrates.

Simple carbohydrates are formed when complex carbohydrates are hydrated (by adding hydrogen and oxygen ions).

Dehydration of simple carbohydrates causes them to bind together in chains to create complex carbs. This can be reversed.
