The type of membrane that protects internal organs from friction is a membrane.

Solution:

The type of membrane that protects internal organs from friction is known as serous membrane.

It is the transparent liquid that is found in the body cavities. When looking for a direct location, it is mostly found in the heart, lung, and abdominal cavity. Serous fluid acts as a lubricant for organs. By lying within the membrane near the organ, it helps the organ move easily for functioning and reduces stress and friction the organ may have against other organs. The lungs, for example, constantly move to provide air for the body. This fluid allows for this motion and prevents the wear and tear that might occur without serous fluid.

Although serous fluid is important for lubrication, it also can be very harmful to the body. Some diseases cause the serous glands to produce too much serous fluid. As a result is that the membranes that hold the serous fluids are not allowing the organ to move or function properly. This could not only be serious for our lungs but also for our heart that needs to move to supply blood to the body.  

This is the required answer.

eukarya because is is like alche and b is bacteria and d is animals

explanation:

well for one plants are always the producer, so a is the answer. a wolf is more of the consumer(predator) and the deer is the prey so i know those two are out of the question. also mushrooms are fungi/fungus so a is the producer.
