2. Turmeric, the most popular spices of India, belongs to genus ‘Curcuma’ due to the presence of a yellow pigment ‘Curcumin’ which imparts yellow colour to it. The chemical structure of ‘curcumin’ is H CO 3 OCH3 HO OH O OH
3. Diffusion of water across a semi permeable membrane is called osmosis. Due to osmosis raisins when put in plain water swells up whereas when put again in brine solution, they shrivel up.
4. There are about seven nutrients essential to plant growth and health that are only needed in very small quantities. These are manganese, boron, copper, iron, chlorine, molybdenum, and zinc. Though these are present in only small quantities, they are all necessary.
5. Cowper’s gland are accessory sex glands in males are located on the floor of the pelvic cavity. Their secretions contain mucus for lubrication of reproductive tract.
6. Trypsin is an enzyme. The pancreas adds a collection of protein-cutting enzymes, with trypsin playing the central role, that chop the protein chains into pieces just a few amino acids long. Then, enzymes on the surfaces of intestinal cells and inside the cells chop them into amino acids, ready for use throughout the body. Trypsin uses a special serine amino acid in its protein-cutting reaction, and is consequently known as a serine protease.
7. Tetanus is caused by clostridium tetnai bacterium while other are caused by virus.
8. The Haffkine Institute of Mumbai is known for its work on the production of polio vaccine.
9. Baboon is the largest monkey, it is 47 inch long & weight around 90 pounds.
10. White blood cells are blood components that protect the body from infectious agents. Also called leukocytes, white blood cells play an important role in the immune system by identifying, destroying, and removing pathogens, damaged cells, cancerous cells, and foreign matter from the body. Leukocytes originate from bone marrow stem cells and circulate in blood and lymph fluid.
11. Osmosis is defined as the movement of solvent molecules through a semi-permeable membrane to a region tht has a higher solute concentration. Osmosis helps animal cell by bringing about a state of balance between important minerals and body solutions.
