Which of the following statements concerning ribosomes is true?

Biology

Nikitich [7]2 years ago

Answer:

E. All of the above statements are

Explanation:

Ribosomes are organelles found free floating in the cytoplasm or attached to endoplasmic reticulum (RER). They are the site of protein synthesis in a cell. Ribosomes initiate the translation process by binding to the mRNA molecule using their mRNA binding site. Several ribosomes called POLYSOMES are often attached to and translating the same MRNA molecule.

A ribosome contains four (4) binding sites; one for the mRNA and three (P-site, A-site and E-site) for tRNA, which are small RNA molecules that carry and add amino acid to the growing polypeptide chain during the process. In a nutshell, the ribosome via the aid of tRNA is responsible for joining amino acids together to form a polypeptide chain (future protein).

In your own words, explain why a virus such as the rhinovirus, which relies on close contact to spread, might evolve to favor le
Zielflug [23.3K]

Rhinoviruses are transmitted through the air or via contact. We might expect this sort of transmission to require a fairly healthy host (one who gets out and comes into contact with others) and, hence, to select against virulent strains. If we take precautions and try to stay away from people or avoid any contact with people, more hand-washing stations, increased attention to sanitization, and isolation of patients will help to reduce the transmission of the disease and, in the process, may favor the evolution of less virulent strains of the virus.

Four students were asked to classify the activities of the people in the picture below as examples of either potential or kineti
frez [133]

Hi there!

\large\boxed{\text{The first choice.}}

Kinetic Energy (1/2 · mass · velocity²) occurs when an object is in motion, or a force is occurring on the object. An example would be a car in motion.

Potential energy (mass · height · gravity ) is obtained when an object has the ability to do work. An example would be an object on a shelf. It has the potential to fall, and this would cause the potential energy to become converted into kinetic energy.

-----------------------------------------------------------------------------------------------------------

Looking at the examples in the table,  we can sort them as such:

Girl swimming laps- Kinetic energy because the girl is in motion.

Boy on diving board - Potential energy because the boy is not in motion, but has the potential to be in motion.

Girl hitting volleyball - Kinetic energy because the volleyball is in motion.

Boy holding volleyball- Potential energy because the volleyball is stationary and has the potential to be in motion.

Therefore, the correct table is table 1.

Which term best describes the macromolecule shown below? А monosaccharide В polysaccharide С amino acid D nucleic acid​
nadezda [96]

Answer:

B. Polysaccharide

Explanation:

A polysaccharide is a carbohydrate molecule made up of several units of monomers called monosaccharides linked together by glycosidic bonds. The monosaccharide is the simplest unit of a carbohydrate with the general formula, (CH2O)n.

However, the monosaccharides, which include glucose, fructose, galactose etc can link up by a bond to form a much larger carbohydrate molecule called POLYSACCHARIDE. As depicted in the image attached to this question, each ring is a monosaccharide, which becomes linked to one another to form a polymer called polysaccharide. Examples of polysaccharides are starch, glycogen, cellulose
