Question

Write the rall of nucleusDefine diffusion and effusion

Answer 1

ROLL OF NECLEUS==The nucleus is an organelle found in eukaryotic cells. Inside its fully-enclosed nuclear membrane, it contains the majority of the cell's genetic material. ... The nucleus maintains the security of the genes and controls the functions of the entire cell by regulating gene expression.

DEFINITION OF DIFFUSION== Diffusion is faster at higher temperatures because the gas molecules have greater kinetic energy.

DEFINITION OF EFFUSION==Effusion refers to the movement of gas particles through a small hole. Graham's Law states that the effusion rate of a gas is inversely proportional to the square root of the mass of its particles.
