An element has atomic number 21 and atomic mass 44.95592 identify the incorrect statement regarding how to interpret and use this information A. The atom must have 21 protons
B. The atomic mass of 44.95592 is created by the sum of protons and neutrons
C. An individual Adam of this element would have 21 neutrons
D. In neutral atom of this element has 21 electrons
E. An individual item of this element would likely have an actual mass of 45

Not judging, but you probably would've gotten the answer if you posted in the Chemistry subject.

C would be the incorrect statement.

Explanation:

When doing the calculations for finding the neutrons, you would get around 24 neutrons, since the mass is about 45 amu. 21 would be the number of protons.

Hope this helps :)

answer; i believe the answer is hydraulic action;

these muscles maintain the blood pressure in the vessels. the smooth muscles are innervated by nerves of the autonomic nervous system. when the muscles contract, they cause vasoconstriction of the vessels and increase blood pressure. when the muscles relax, they enable vasodilation of the   blood vessels hence reduce blood pressure.
