Answer:
Yet, nerve cells in your brain, also called neurons, do not renew themselves. They do not divide at all. There are very few exceptions to this rule – only two special places in the brain can give birth to new neurons.
Explanation:
The three correct answers are;
B. forming waxy leaf coverings
D. storing energy in fat cells
E. forming cell membranes
Lipids are a large group of biological molecules that include phospholipids, fats, oils, waxes and some steroids. Almost all lipids are hydrophobic (i.e. insoluble in water). Lipids play many important different functions in a cell. Lipids are vital component of all cellular membranes. They store energy in the form of fats in the body. Waxy coverings on some leaves are composed of lipids. Lipids are also essential for heat insulation, cellular communication and protection.
Endospore staining is used to stain the spore which reside inside the microorganisms, and unlike the exospores, are not present outside the microbial cells. The endospore stain penetrates the microbial cells, and then stain the endospore.
The correct answer is Eutrophication.
When a body of water become enriched with nutrients and minerals and induces growth of algae and plants is referred to as eutrophication.
The process of eutrophication can result to water body depletion.
When there is increase in nutrient levels there is increase in phytoplankton in the water body.
Discharge of nitrates which contain sewage, fertilizer, and detergents in aquatic system may induce the eutrophication.
