Why is the mixing of fresh water and salt water in the bay important?
Setler [38]

Answer:

When the salt water is mixed with fresh water,it is called brakish water which have the salinity 0.5 to 35 ppt.

Explanation:

The mixing of fresh and salt water is important for aquatic organisms.

The catadromous fish born in marine habitat but they spend their rest of life in the fresh water where growing and maturation takes place.

Ex- Eel is the common example of catadromous fish.

Like wise,

Anadromous fish born in fresh water and spends their life in the sea and return to fresh water for spawning.

For example Salmon, smelt, shad, are common examples.

Thus mixing of water is important for breeding and growing of these fishes.

More over, the brakish water contain world's most diversified life forms.

enzymes degrade proteins, lipids, and large carbohydrates to smaller building blocks in the digestive tract. why must these macr
Rom4ik [11]

Amino acids, which serve as the "building blocks" of proteins, are disassembled. These tiny molecules can be absorbed through the stomach wall after being released.

<h3>Describe how the macronutrients in your diet are digested and then put back together to form the cell structure.</h3>

The principal macromolecules, from which all life is derived, are macrounits in our diet. The smaller subunits of these macromolecules must be broken down in order to be released. The circulatory system carries the digestively released components to the body's cells. These subunits serve as the building blocks for the macromolecules required for cellular structure and function, which are then put together by cells.

Proteins, lipids, and carbohydrates are examples of macromolecules.

The fact that all three macromolecules are hydrocarbons means that the majority of their atoms are made up of hydrogen and carbon.

Nitrogen atoms are found in proteins and in lipids.

Carbon atoms make up carbohydrates.

Simple carbohydrates are formed when complex carbohydrates are hydrated (by adding hydrogen and oxygen ions).

Dehydration of simple carbohydrates causes them to bind together in chains to create complex carbs. This can be reversed.
