50 x 100 = 5000
when you multiply something with 10,100,1000, etc. you add that many zeros to the end of the first number.
Answer: A). Active transport requires chemical energy to move nutrients from areas of low concentration to areas of high concentration.
Explanation:
Sometimes cells require nutrients such as sodium and potassium to be transported from an area where they are in low concentration to an area where they are in high concentration.
This goes against the concentration gradient where substances are transported from an area of high concentration to one with low concentration as is the case in processes such as osmosis.
This process is called Active transport and describes the use of chemical energy to move nutrients from areas of low concentration to areas of high concentration.
