Answer:
the animal cell will burst
Explanation:
If the salt solution in the animal cell is 30%, it means the water is at a 70% concentration. Outside is 20%, so the water is 80%.
Water will enter the cell. Water is at a higher concentration outside the cell (80%) or a lower concentration inside the cell (70%) by the process of osmosis.
Eventually, the animal cell will burst, because it does not have any cell wall to control the swelling of the cell that occurs as water flows in.
For the first question the answer is D
For the second question the answer is B
Because thelogarithm<span> is the inverse function of the exponential operation, i.e.: if ab=c a , then b=</span>log<span>a(c) b = </span>log<span> a ( c ) .</span>
