Active transport is the moving of molecules across the membrane of the cell against the concentration gradient with the use of ATP.
Low to high concentration. Concentration gradient is the diffusion (movement of molecules from regions of low concentration) from high to low with the gradient. Active transport is from low to high, against the gradient.
The question asks average kinetic energy. So it is only related with the temperature. The higher temperature is, the higher kinetic energy is. So the answer is (4).
Answer:
Answer choice A
Explanation:
When an electron is transferred to another atom, both atoms involved become ions.
D = m / V
d = 1300 g / 743 cm³
d = 1.749 g/cm³
