polarizing activity

The penetration of the sperm activates the egg and initiates a series of changes in the egg cortex and in the egg cytoplasm. Ovulation in the human female occurs at the secondary oocyte stage in which meiosis - I has been completed and the first polar body has been released but ..

Determination of Optical Activity using a Polarimeter - Two Nicol prisms (got by combining two prisms of Iceland spar suitably cut) are placed between the source of monochromatic light, S, and the eye. Light passes through the first Nicol prism, P, the polarizer and gets plane h..

Chemical reactions mostly take place in solutions. Solution chemistry plays a very significant role in chemistry. All chemical substances are made up of either polar units (called ions) or non-polar units. The activity of these entities is more evident and pronounced i..

Water constitutes nearly three-fourths of the Earth's surface and it composes a large proportion of all living plant and animal matter. Approximately 70% of human body is water. Man drinks about 2 liters of water daily and it is required in abundance for domestic use, agricultural activities..

>The proteins present in the membrane may function as carriers or receptors or enzymes. Transport across membranes involves several mechanisms. There are processes like diffusion and osmosis, which do not require energy or activity of the cell. Diffusion involves movement of molecules fro..
