Read the following statements that describe what happens as an impulse travels. What is the correct order in which the steps occur? 1) The impulse continues to travel down the axon away from the cell body. 2) Na+ gates close and K+ ions flow back out of the cell restoring the resting potential. 3) Gated K+ and Na+ channels are closed. The inside of the cell is slightly negative compared to the outside. 4) The neuron receives a stimulus great enough to start an impulse. 5) Gated Na+ channels open. The net movement of Na+ ions into the cell produces the action potential..

Explain the thinking of the limb cells

Answers

This is a very biased question and not posed correctly. I would advise to ask your teacher what did he mean exactly by this. The reason why I'm saying this is because thinking is a concept that is used for higher-order beings which are more complex (apes and other mammals) - if not only used for humans. For that reason, it's not valid to say limb cells think.

Which statement BEST describes common communicable diseases?A.

Most communicable diseases are either bacterial or viral and infect the respiratory tract.

B.

All communicable diseases are viruses that cause pneumonia.

C.

Most communicable disease are bacteria and viruses that infect the intestinal tract.

D.

All communicable diseases are bacteria that grow in the respiratory tract.

after reading this:

A communicable disease is an illness transmitted through contact with microorganisms. People, animals, food, surfaces, and air can all be carriers of the microorganisms that pass infectious illnesses from one host to the next. The exchange of fluids or contact with a contaminated substance or individual may be enough to allow a communicable disease to spread.

what do you think the answer is?

Answers

By definition, communicable diseases are diseases that can be passed from one person to another. Also, not all communicable diseases are caused by bacteria only nor virus only. So therefore, the answer would be option A. The statement that BEST describes common communicable diseases is this: Most communicable diseases are either bacterial or viral and infect the respiratory tract. Hope this answer helps.

Most communicable diseases are either bacterial or viral and infect the respiratory tract.

Communicable, or infectious diseases, are generated by microorganisms such as parasites, fungi, bacteria, and viruses, which can be spread, directly or indirectly, from one person to person.

A majority of upper respiratory diseases are due to self-limited viral epidemics. Occasionally, bacterial germs may produce upper respiratory infections. Most often, upper respiratory virus is communicable and can spread from person to person by breathing respiratory droplets from coughing or sneezing.
