In the 1 question mark the “o<“ -phospholipids and the big molecules must be proteins
2 — active requires ATP, passive doesn’t; it depends on the concentration gradient: passive goes along the gradient (where concentration is little) active moves where concentration is big
3 - Because of the concentration gradient - diffusion is passive so the salt is moving out of the cell
4-The cell will be little because water moves out of the cell ( concentration of salt inside the cell is less than outside)
:)
Usually it is 25% for energy pyramids
Im pretty sure everything exept sound
Answer:
The difference between molecular biology and comparative biochemistry are:
Molecular biology is the branch of biology in which we study about the chemical composition and structure of atoms of macromolecules such as protein and nucleic acid which are the main component of life forming substances, while Comparative biochemistry is a branch of chemistry in which we study the similarities and differences between different biological processes that occurs in different living organisms.
The phosphate group and the deoxyribose sugar.
More info: the three parts of a nucleotide are the PHOSPHATE GROUP, DEOXYRIBOSE SUGAR, and the NITROGENOUS BASE.
