What happens as a result of osmosis when an animal cell containing 1% sugars solution

1 answer:

3 0

The process of osmosis is the movement of water through a selectively permeable membrane from an area of higher concentration to an area of lower concentration.

If a living cell is placed in 1% sugar solution outside the cell would be hyper-tonic relative to the inside of cell. There would be a gradient between the inside cell and outside environment. Osmosis is the movement from higher to lower concentration, therefore the cell will lose water and it would dehydrate.

Almost 50 percent of water withdrawn in the US, is used up by thermoelectric power plants. The table below shows the amount of w

sp2606 [1]

Answer:

The number of thermal power plants increased between 1950 and 1975.

Explanation:

Here, the table that shows the amount of water withdrawn in billion gallons per year, between 1950 and 2005,

Year 1950 1965 1975 1990 2005

Amount 180 340 420 410 410

Since, 420 > 180,

Also, 50 percent of water withdrawn is used up by thermometric power plants.

Thus, thermal power plants in 1975 > thermal power plant in 1950

Therefore, the number of thermal power plants increased between 1950 and 1975.

Second option is correct.

Note : first option is incorrect.

Since, by the above table,

The least amount of water used by power plant is 180 billion gallons per year,

Thus, third option is incorrect,

Now, the table does not represents energy produced,

Fourth option can not be said correct.

Sodium and potassium ions move in and out of the axon when the membrane is ______

Ostrovityanka [42]

Answer:

Answer : Depolarized

Explanation:

Sodium and Potassium ions tend to move inside of the axin when the membrane is depolarized.

A change in polarity occurs in the axon membrane when a nerve impulse travels across it. At the beginning of an action potential or nerve impulse , the ions of sodium tend to move inside of axon causing depolarization. As a result potassium ions tend to move outside of the axon causing re polarization. Hence, this effect causes the nerve impulse to travel in one direction only inside the axon.
