Answer:

A. whether the glycoproteins or capsid proteins on its surface recognize those of the host cells.

Explanation:

Virus has different surface proteins that are recognized by the receptors present on its host cell. The range of a virus is determined by the recognition of these proteins by the host cell.

The interaction between the receptor on the host cell and surface proteins on the viral capsid is important for viral genome entry in the host cell and to determine the range of the host cells.

If the surface protein of the virus is not able to bind to the receptor on any cell then the virus can not infect the cell. For example, the HIV virus infects only those cell which have CD4 receptors. So the right answer is A.

Answer:

The correct answer is - biological hierarchy.

Explanation:

Biological hierarchy can be understand as the comprehension of the simplest form of the life to the most broadest and complex form of the life. It includes from the atoms which is a smallest structure and cells to the interactions of in between non living things and living things.

The broadest or highest level of the organization is biosphere in biological hierarchy in includes all other living organisms with non living things present in it. atoms to cell, tissue, organ, organ system to organism. these organisms shows interaction with each other and called populations that form communities, to ecosystem and finally biosphere.

Thus, the correct answer is - biological hierarchy.

Write a paragraph comparing the organelles in a cell to the organs in your body
Komok [63]
Assuming a paragraph is 4-6 sentences ill just right a 5 sentence paragraph.

Organelles in an cell help with doing tasks to keep the cell alive and moving. Just like organs in the body, which break down food and help with keeping are bodies in shape. each organelle and a organ in a human body have certain tasks to complete. A difference is in a cell the organelle are far smaller then that of a humans organs.

As part of their normal function, many proteins bind to DNA briefly and then release it again. Which types of interactions might
Harman [31]

Answer:

Non-covalent interactions.

Explanation:

DNA is present as genetic material in all the living organism except some viruses. DNA also perform important other functions - code for proteins, used as a source of energy.

The DA binds with protein to perform their functions. These proteins may acts as activator for DNA. The proteins binds in the non covalent interactions ( ionic bonding, hydrogen bonding, vanderwalls and hydrophobic interaction) so that proteins may easily detach from the proteins. These interactions helps in the attachment and easily detachment of proteins from DNA.

Thus, the correct answer is non-covalent interaction.
