If a people consume more protein than their body needs, the excess protein is __________. excreted in their urine deaminated and used/stored as glucose or fat stored in their muscles excreted in their feces

Answers

When you consume more protein than your body needs, the excess protein is used to provide your body with energy or turned into fat.

How is protein essential for the body?

The protein need for the body depends on the age, physical activities, development and changes. For all these processes, body need a large amount of protein.  Our body is at the phase of breaking and building muscles, so high amount of protein is not harmful. Excess amount of protein is stored in the body in form of fats and break down when need for body energy requirements. So if the amount is increase it will result in weight gain and body size.  

Even a high amount of proteins is healthy and safe, but massive increase in amount can cause harm to the body.  

Thus,harmful effects of massive amount of protein depend on patient health.

How does the right hand rule apply?

This relationship is represented by the right-hand rule: the thumb of the right hand indicates the conventional direction of electric current; and the other fingers, by wrapping the conductor through which the current passes, give the direction of the magnetic field lines

By right-hand rule, if the right-hand thumb points in the direction of a current, the magnetic field at a point will be given by the direction of curl of fingers at that point.

Cyanobacteria are photosynthetic marine organisms. why would these organisms likely be found only in shallow ocean zones? the current in deeper ocean zones is too traumatic. the amount of oxygen in deeper ocean zones is too high. the amount of light in deeper ocean zones is too dim. the amount of pressure in deeper ocean zones is too low.

Answers

Cyanobacteria as photosynthetic organisms would likely be found only in shallow ocean zones because the amount of light in deeper ocean zones is too dim.

What are cyanobacteria?

Cyanobacteria are any of the very many photosynthetic prokaryotic microorganisms, of phylum Cyanobacteria, once known as blue-green algae.

Cyanobacteria are photosynthetic organisms, hence, require sunlight energy to undergo the process.

Light from the sun can only reach the photic zone of a water body, hence, cyanobacteria as photosynthetic organisms would likely be found only in shallow ocean zones because the amount of light in deeper ocean zones is too dim.

Answer:

The amount of light in deeper ocean zones is too dim.

Explanation:

Not: the amount of oxygen in deeper ocean zones is too high, because their is barely any oxygen in deep ocean. Not:

The current in deeper ocean zones is too traumatic, it is very still, no currents.

The amount of pressure in deeper ocean zones is too low, there is high pressure deep ocean, like for example, when you go deeper in water your ears get filled, like you can't hear because of the high pressure.

So the answer is; The amount of light in deeper ocean zones is too dim.
