Answer 1

Answer:

The answer is "Transgenic DNA".

Explanation:

A transgenic, or genetically modified, organism is one that has been altered through recombinant DNA technology, which involves either the combining of DNA from different genomes or the insertion of foreign DNA into a genome.

This is definition of transgenic DNA which matches well with the description of the example that you gave. Since the doctors are inserting a DNA into a bacteria that they are trying to study, they had to insert it into a a foreign DNA to be able to know what this new form of bacteria is.

Good luck

describe the role of the liver in the assimilation of amino acids by converting them to proteins.

Answers

Explanation:

The liver is important in assimilation. For example, it converts glucose into glycogen (a complex carbohydrate used for storage) and amino acids into proteins. ... This is the removal of the nitrogen-containing part of amino acids, to form urea, followed by the release of energy from the remainder of the amino acid.

The deamination process involves the liver. This involves the release of energy from the remaining amino acid after the nitrogen-containing portion of the amino acid is removed to generate urea.

What is assimilation of amino acids in liver?

Assimilation is the transport of molecules from digested food into the body's cells, where they are utilized and eventually become a part of the cells.

Extra glucose in the blood that reaches the liver is either broken down through respiration to produce energy for other uses or turned into glycogen (animal starch) for storage.

The complex proteins and carbs are broken down into glucose and amino acids during absorption. As a result, glucose is used in respiration while amino acids are obtained for the creation of new proteins.

Therefore, the role of the liver in the assimilation of amino acids by converting them to proteins.

how are enzymes, proteins, and amino acids related, and what is their role in a viral take over?

Answers

Answer:

Amino acids are building blocks to proteins, and the combination and order of them determines what protein is actually being built. Then enzymes are a type of protein which facilitates or catalyses a process, such as the breaking down of molecules in your food. In a viral takeover, the virus uses your body's ribosomes to create viral proteins (consisting of amino acids). Viral enzymes actualy facilitate this by inserting viral DNA into the hostcell's DNA.

Why is water called universal solvent?

Answers

Water is called a universal solvent because it can act as a solvent in many

different solutions.

Water comprises of the elements Hydrogen and Oxygen and is very

important which is why it is a compound which is commonly present

everywhere across the earth.

Water is a solvent and has the ability to dissolve different types of solutes

and  solutions as a result of its high polarity. The substances must however

Answers

the answer A, steroids ; separate the cytoplasm from the environment

Answer:

B) Waxes, prevents water loss and repels water

Explanation:

Waxes, steroids, phospholipids, and triglycerides are types of lipids. All of them are made of Hydrocarbon chains that are hydrophobic.

Triglycerides (fats) - Storage molecules for the body's energy

Steroids - Sex hormones and cholesterol

Phospholipids - Cell membrane (Separates cytoplasm from the environment)

Therefore, Answer choice B) Waxes, prevents water loss, and repels water, is the only answer that correctly matches with the provided answers.
