Some neuroglial cells produce the components of the electrical insulator called Myelin.
<h3>What functions do neuroglial cells perform?</h3>
A broad class of cells known as neuroglia assist neurons during their growth and metabolism. They are in charge of preserving immune protection and homeostatic regulation in the neurological system.
Glia are non-neuronal cells of the central nervous system (brain and spinal cord) and the peripheral nervous system that do not generate electrical impulses. They are also known as glial cells (gliocytes) or neuroglia.
Glial cells are non-excitable brain tissue cells that cushion, support, and insulate neurons. Neurons. excitable nerve cells are those that can transfer electrical signals and react.
Support cells, or neuroglial cells, work with neurons to help them survive and thrive in their ideal environments.

Answer:
(b) Digestive tract and liver
Explanation:
The digestive system consists of the digestive tract and liver. The digestive tract is made up of a large number of parts. These parts include the esophagus, stomach, intestines, rectum, etc. Food enters the mouth and travels down the digestive tract and out passing the rectum. The liver is where the blood passes through and it is responsible for many functions such as the metabolizing of fats and proteins, separating and storing vitamins and minerals, regulating different chemicals found in the blood, etc.
The binary fission , is the asexual reproduction which is found in prokaryotes. In binary fission a cell divide into two daughter cell. Amoeba is the best example of binary fission in which gentic material is divide and via mitotic division further cell is divide into to daughter cell . So we conclude that, the result of binary fission is formation of daughter cell.
Answer:
handle and the dial is the correct answer
In a hydra, digestion is completed intracellularly.
Hence option (a) is correct.
Small, freshwater organisms of the phylum Cnidaria and class Hydrozoa are grouped under the genus Hydra. They are indigenous to temperate and tropical climates.
The digestion takes place intracellularly in Hydra.
Because of their ability to regenerate and the fact that they don't appear to age or experience old age, hydra have drawn the attention of biologists.
Like most other cnidarians, hydras have a pretty straightforward digestive system.
They have a two-way digestive system, which differs from mammals in that food and waste enter and exit through the same aperture. A "blind gut" is the name for this configuration.
The center of the hydra's body is occupied by its digestive tract.
