Answer:
Proteins
Explanation:
There are proteins in the membrane that have channels for large polar molecules to move into or out of the cell since the plasma membrane is made of a phospholipid bilayer where the inside is non polar. This means large polar molecules need help from proteins to cross the plasma membrane.
If these are the choices:
The ability to halt the cell cycle in response to DNA damage.
The ability to halt the cell cycle in response to the chromosomes not properly aligning on the metaphase plate.
The ability to repair DNA damage.
The ability to activate Cdks.
The ability to stimulate cell death processes if the cell is irreparably damaged.
MY ANSWERS ARE:

Answer: t= -1.60
Explanation:
Let 
be the population mean weight of pigs.
As per given , we have
Sample size : n= 16
Sample mean =
Sample standard deviation : 
<em>Since the population standard deviation is not known so the test is a</em><em> t-test.</em>
Test statistic for population mean : 
(Substitute all the values.)
Hence, the value of the test statistic needed to test the null hypothesis : t= -1.60
Answer: Each Gamete will have 19 chromosomes
Explanation: because gametes contain HALF the chromosomes contained in normal diploid cells of the body, so you take half of 38, which is equal to 19.
Hope that helps!
