1) The answer will be molecules (w) & tissues (aq).
Explanation: If we look at the levels of organization of physiological structures at the first stage we will find chemical level. It includes chemical substances such as atoms, ions, molecules etc. The next level is cellular level which includes different types of cells (Ex: muscle, nerve etc.). The next level is tissue level. It includes a group of cells which do a specific task (Ex: epithelial, muscle etc.). Final two levels are organ (Ex: Heart, kidney etc.) & system level (Ex: reproductive system).
2) The answer will be microvilli (u).
Explanation: Microvilli are the microscopic cellular membrane protrusion that increase the surface area of the cell & help in absorption & secretion. Ex: Small intestine (Human).
