Osmoregulation is a part of homeostasis which maintain of constant internal environment. It control the water and salt  content with in the body. This process occurs in plants and animals allow to maintain a balance.Excess water, electrolytes, waste material are transported to the kidney and help inmaintaining osmotic balance.Biological system exchange water and nutrient with the environment by the way food and water consuption and remove in the form of urine, sweat and feces. In mammalian system three major compartment; blood plasma, intracellular and intercellular fluid are important for regulation.Although kidneys are major osmoregulation organ in mammalian system., they function to filter blood and maintain osmolarity. The nephron is the functional unit of the kidney which filter the blood. The nephron filters, exchanges water and solutes with blood vessels and tissue fluid. IN PLANTS, like as halophytes show sodium dependence for growth and dewelopment have specialized structures like salt glands accomodate high salt concentration.

Fatty acid synthesis:  1- it occurs in prokaryotes and eukaryotes         2-NADPH is reductant                3-Fatty acuds are linked to ACP       4-the enzyme involved is fatty acid syntases                                  Oxidation:   1-it occurs in mitochondria of eukaryotes       2-NADH is reductant       3-Fatty acids are linked to CoA              4-Many enzymes are involved 

Peroxisomes, catalase,mitochondria.These organelle consists of 50 different enzymes involved in the metabolism process

Peristaltic movements are rythmic contractions and relaxations in the oesophagus to regulate the movement of food during digestion.

Department of zoology and biomedical technology is one of the best institute of the area

Yes, you can especially in the Universities present in the south like Pondicherry University, Annamalai University and possibly in Pune University, as these universities are near to the coastal areas.

Absolutely, It had a very wide scope as you will go deep into it, you will find that it is connected to all the fields of biology, even those are worthless without this. 

After doing Microbiology you can choose career diagnostic labs, become a professor, and can do research on different lethal microbial diseases.
