Why do plant animal cells both have mitochondria?

Chemistry
1 answer:
LuckyWell [14K]3 years ago
5 0
The mitochondria is the powerhouse of a cell. They are important because they are an energy factor for both plant and animal cells. They take the food you eat, and turn that as energy for the rest of the cell to use. It is critical that every cell has one to survive whether plant or animal.

erastova [34]
<em />If 100 brownies require 6 eggs, 5 cups of flour, and 2 sticks of butter. Then, 50 brownies should require half of those required to make 100 brownies. Use ratio and proportion to determine the number of eggs needed:

100/50 = 6/x
x = 3<span />

How many milligrams of AgNO3 is required to completely react with 81.5 mg LiOH?
BartSMP [9]

Answer:

m_{AgNO_3}=577.6mg

Explanation:

Hello there!

In this case, according to the given chemical reaction, it is first necessary to compute the moles of reacting LiOH given its molar mass:

n_{LiOH}=81.5mg*\frac{1g}{1000mg}*\frac{1mol}{23.95g}  =0.0034molLiOH

Thus, since there is a 1:1 mole ratio between lithium hydroxide and silver nitrate (169.87 g/mol) the resulting milligrams turn out to be:

m_{ AgNO_3}=0.0034molLiOH*\frac{1molAgNO_3}{1molLiOH} *\frac{169.87gAgNO_3}{1molAgNO_3} *\frac{1000gAgNO_3}{1gAgNO_3} \\\\m_{AgNO_3}=577.6mg

Best regards!

The solution in the two arms of the U-tube are separated by a membrane that is permeable to water and glucose but not to sucrose
Gnom [1K]

Answer:

The liquid level will rise in Side A and drop in Side B.

Step-by-step explanation:

The membrane is impermeable to sucrose, but permeable to sucrose and water.

<u>      Side A   </u>    <u>    Side B    </u>  

2 M sucrose   1 M sucrose

1 M glucose   2 M glucose

(a) Ignoring osmotic effects

The glucose will diffuse spontaneously from the side with higher concentration to that of lower concentration until equilibrium is established. There is no change in volume on either side.

At this point, we have

<u>     Side A       </u>   <u>        Side B   </u>      

2    M sucrose    1 M sucrose

1.5 M glucose    1.5 M glucose

=====

(b) With osmotic effects

The solute concentration on Side A is greater than on Side B.

Water will diffuse into Side A.

The liquid level will rise in Side A and drop in Side B.
