Answer:

Microglial cells

Explanation:

Microglial cells are one of the various types of neuroglial cells in the central nervous system. Microglial cells are the small cells and have thin slender processes. Many spine-shaped outgrowths come out of these processes. Microglial cells serve as phagocytes of the central nervous system. These cells clean the cellular debris that is generated during the normal development of the nervous system. Microglial cells also perform phagocytosis of microbes and damaged nervous tissue.

Which of the following ions is a polyatomic ion?

OLga [1]

The correct answer is option $NH{{+} \atop {4}} \right.$ .

The $NH{{+} \atop {4}} \right.$ is an ion made up of two atoms nitrogen and hydrogen.

The polyatomic ions are those ions, which are formed by the binding of the two or more elements, which has a charge and act as an ion. As all others are formed by a single atom, they are not polyatomic, only $NH{{+} \atop {4}} \right.$ is formed by two atoms, hence, it is an polyatomic ion.

Which of the following statements about a typical plasma membrane is correct?

lawyer [7]

Answer:

Explanation:

Typically across all life, the plasma membrane of cells is made up of a bilipid layer of phospholipids. The phosphate ends of the molecules, which are hydrophilic hence ‘face’ the interior and exterior of the cells. The fatty acid chains, which are hydrophobic are embedded in between because they no charges hence do not interact well with charged molecules. The phosphate ends, on the other hand, are negatively charged hence can interact well with the polar water molecules. It is therefore usually a challenge for molecules with charges to diffuse across the membrane without the help of channel proteins that will help them cross the hydrophobic layer.
