Why is it important for the cell membrane to allow materials to enter and leave the cell

1 answer:

5 0

Cell membrane needs to allow and exit the materials that enter the cell because the cell needs nutrients and these nutrients are converted into molecules that aid in many cellular activities like repair, divide and form structures and biomolecules.
Also to excrete wastes and other harmful materials for the cell.
This continues because the cell wants to attain homeostasis.

Homeostasis is the state where the internal and external part of the body maintains and establishes balance and equilibrium. This is achieved through cellular processes in the body, the integumentary system regulates the body temperature, the hypothalamus –hunger and thirst of the individual and other interrelated organ systems that make the body healthy and in the state of equilibrium. Now, when diseases or disorders appear they disrupt the organ systems in the body thus, causing imbalance state –high fever, inability to focus and etc.

Part C

IrinaVladis [17]

Answer:

(i) 1 moles of C

(ii) 4.5 moles of C

Explanation:

The Chemical equation is as follow,

A + 2 B → C

This chemical equation can be translated as;

(i) 1 mole of A reacts with 2 moles of B

(ii) 1 mole of A produces 1 mole of C

(iii) 2 moles of B reacts with 1 mole of A

(iv) 2 moles of B produces 1 mole of C

(v) 1 mole of C is produced by 1 mole of A and 2 moles of B

Therefore to find the number of moles of C produced by 2 mole of B we will do following proportional method.

As,

2 moles of B produced = 1 mole of C

So,

2 moles of B will produce = X moles of C

Solving for X,

X = 2 moles × 1 mole / 2 moles

X = 1 moles of C

Note:

In above problem the given moles were the same as that present in balance equation so incase if the moles are different from that of the equation then the method shown above can be used to solve it.

Lets try it for 9 moles of B:

As,

2 moles of B produced = 1 mole of C

So,

9 moles of B will produce = X moles of C

Solving for X,

X = 9 moles × 1 mole / 2 moles

X = 4.5 moles of C
