what is the structure of a virus?

Answers

Answer 1
Structure. Bacteria (singular: bacterium) are classified as prokaryotes, which are single-celled organisms with a simple internal structure that lacks a nucleus, and contains DNA that either floats freely in a twisted, thread-like mass called the nucleoid, or in separate, circular pieces called plasmids. All viruses contain nucleic acid, either DNA or RNA (but not both), and a protein coat, which encases the nucleic acid. ... Some viruses are also enclosed by an envelope of fat and protein molecules. In its infective form, outside the cell, a virus particle is called a virion.
Answer 2

Structure of a virus

Explanation:

At the center of all viruses the DNA or RNA is found enclosed by the capsid. The Capsid is a capsomere (type of protein) coat that is designed to protect the DNA or RNA.

The capsomere contains genes that allow the virus to transfer its nucleic acid into the host cell.

Explanation:

It has become sensitive to the trend of global warming the surface air temperature has risen by 0.9 °C. Many regions have experiences the record breaking high temperature in otherwise winter months since 20 century. Tundra natural fires release carbon dioxide gas in the atmosphere.

name the organ that is adapted for gaseous exchange in humans

Answers

Answer:

Lungs.

Explanation:

Lungs are the organs that are responsible for gaseous exchange in humans. The lungs absorb oxygen from the air that is required for the process of respiration while on the other hand, carbon dioxide is transferred from the cells to the lungs through blood because carbondioxide gas is a waste material that is produced during respiration so it can be removed from the body with the help of lungs..

if something needed to enter the cell and couldn't go through the phospholipid bilayer, how else could it enter the cell?

Answers

Answer:

Through facilitated diffusion

Explanation:

A molecule that finds it difficult to enter through the cell membrane's phospholipid bilyaer can be assisted in doing so through a process known as facilitated diffusion.

Ordinary diffusion will not permit the movement of molecules against a concentration gradient or molecules can be prevented from passing the phospholipid bilayer due to their sizes/charges. Within the phospholipid bilayer exists special passages lined with carrier or channel proteins.

These proteins facilitate some molecules that will ordinarily not pass through the bilayer to pass through their special passages. This process is referred to as facilitated diffusion.

Relate the surface area of a cell to the transport of materials.

Answers

If the size of a cell increases it will be more difficult (all other things being equal) for diffusion to transport materials out of the cell. Therefore, less of the cell's interior will be able to come in contact with the cell's surface. If less of it comes in contact, less of it can cross the cell membrane.
