2)pumps move substances from areas of low concentration to areas of high concentration.
3)pumps always move substances out of the cell.
4)pumps always move substances into the cell.

answer:

the answer is 4

step-by-step explanation:

answer:

4)pumps always move substances into the cell.

step-by-step explanation:

Given :
Sin x = 4/5
Using the rule of SOH CAH TOA,
we know that,
Sin x = opposite/Hypotenuse
So,
When the triangle is dilated, the opposite side will be dilated to 8 and the Hypotenuse will be dilated to to 10.
which means 4/5 will become 8/10
and hence,
8/10 after simplifying will be 4/5.Thus there is no change.
