What is the function of a nucleus?

contains genetic material, which controls the activities of the cell

controls the movement of substances into and out of the cell

most chemical processes take place here, controlled by enzymes

Which is (more) true?

Osmosis is the movement of water from a less concentrated solution to a more concentrated solution through a partially permeable membrane.

Osmosis is when particles continue to move from a high to a low concentration while there is a concentration gradient.

a connection between two neurones.

nerve fibres that carry signals to the effector muscle or gland

nerve fibres that carry signals from the receptors in the sense organs to the central nervous system
