The answer to this question would be: by producing buffer

The pH of optimal growth of bacteria might be different. Some bacteria can grow in an acid condition called acidophile, other live in base condition called alkaliphiles and the rest live in neutral pH condition called neutrophiles. The bacteria can maintain their internal pH by producing acid, base or buffer. If the surrounding pH is too acid, the bacteria can reduce the H+ concentration by producing base. If the condition is too alkali/base, the bacteria can produce acid by doing fermentation.

Neurogenesis

As recently as two decades ago, scientists believed we were born with all the neurons we would ever have. But the discovery of neurogenesis occurring in certain brain areas in monkeys gave rise to the hope that someday scientists will be able to induce the adult human brain to heal itself.

Neurogenesis is the process by which new neurons are created and developed in the brain. The new neurons are created by neural stem cells and it happens in almost all species of animals. Neurogenesis is effectual during embryonic development and completely through adult life in different organisms.

Explain in detail about Phospholipid Bilayer.
erica [24]

A phospholipid bilayer or lipid bilayer is a double layer of lipids in a cell membrane which has a hydrophobic and a hydrophilic part.

Hydrophobic - expelled by water

Hydrophilic - attracted to water

The layers form the cell membrane which means that it's functions are the same as the functions of a cell membrane, and are critic to the cells functioning.
