Paragraph about cell wall

Physics
2 answers:
algol [13]2 years ago
7 0
Animal cells do not have cell walls, nor do protozoa. Cell walls protect the cells from damage. It is also there to make the cell strong, to keep its shape, and to control the growing of the cell and plant. The cell wall is the tough, usually flexible but sometimes fairly rigid layer that surrounds some types of cells

All you need to know about the cell wall is that it protects the cells inside of it.

An apple is held completely submerged just below the surface of water in a container. The apple is then moved to a deeper point
Tresset [83]

Answer:

Explanation:

When the apple is held submerged in water , it experiences a buoyant force due to which it floats in water . One has to apply downward force to keep it submerged. The lower the buoyant force , lower the force needed to submerge it in water.

When apple is held at much deeper point , it experience greater pressure due to column of water around it . So its size or its volume decreases . But its weight remains the same . Due to less volume , buoyant force also decreases ( buoyant force is equal to weight of displaced volume of water. )

Due to buoyant force becoming less , force needed on apple  in downward direction will also be less.

A speedy tortoise can run with a speed of <img src="https://tex.z-dn.net/?f=v_T" id="TexFormula1" title="v_T" alt="v_T" align="a
Vinil7 [7]

Answer:

t_{H}  = t_{T}  - 60

Explanation:

Thinking process:

Let:

distance = speed × time

for the hare:

d_{H}  = s_{H} t_{H}

for the tortoise:

d_{T}  = s_{T} t_{T}

Let the length of the shell be s. Then the two are related. So:

d_{H}  = d_{T}  - s

Let's say the hare ran at x times the speed of the tortoise:

s_{H}  = xs_{T}

So, the equation still holds : t_{H}  = t_{T}  - 60
