Which of the following is a difference between primary and secondary active transport? Which of the following is a difference between primary and secondary active transport? In primary active transport, the transport protein gets phosphorylated; in secondary active transport, the transport protein is not phosphorylated. Primary active transport is driven by secondary active transport. Energy is required for primary active transport, but not secondary active transport. Primary active transport moves solutes in opposite directions while secondary transport moves solutes in the same direction

that is a club

explanation:

i am good at it i think hope its right

the level of progesterone is low at the pre-ovulatory phase of the cycle but it gradually increases and the levels are high at the luteal phase. if pregnancy occurs, the level of progesterone will be high throughout the pregnancy.

if egg is fertilized and the mother gets pregnant, progesterone starts preparing the uterus for the implantation. it starts building up the lining of uterus and make it hostile of the period of pregnancy.

the titanic would be the correct answer

-3

-8

-3

so the population decreased by 24 because 3+3+8+10+2=26-2=24.
