Pseudopodia are developed in amoeba. Amoeba engulfs its food particles by forming pseudopodia around it. The food particle gets surrounded by encircling pseudopodia’s tips.

Rice water contains starch, hence when iodine solution is added to rice water it turns blue-black.

Valves prevent backward fow of blood as they are located at each end of two ventricles and act as one way inlet.

Pancreas secretes pancreatic Juice which contains trypsin, lipase and pancreatic amylase. Trypsin digests the proteins, lipase breaks down the fat droplets already emulsifed by bile salts and pancreatic amylase breaks down the starch.

The oxygen during photosynthesis comes from split water.

The blood leaving the tissues becomes richer in carbon dioxide. When the oxygenated blood passes through the capillaries of the tissue.

Living organisms are well organised structures; they can have tissues, tissues have cells, cells have smaller components in them, and so on. Living creatures keep repairing and maintaining their structures

The opening and closing of the pore is a function of the guard cells. The guard cells swell when water fows into them, causing the stomatal pore to open. Similarly, the pore closes if the guard cells shrink.
