Answer:
Option (B).
Explanation:
Neurons or nerve cell are the basic structural and functional unit of the nervous system. Fibers are the thread like long projection of the nerve cells.
Neurons are classified into three fibers- Group A fibers, B fibers and C fibers. The group C fibers cannot capable of doing the saltatory conduction of the nerve impulse because they are unmyelinated.
Thus, the correct answer is option (B).
Answer: Single covalent bond in the long hydrocarbon chain.
Saturated fatty acids are long chains of hydrocarbon ( with single covalent bond) ending with the carboxylic group (-COOH). This means those fatty acids which possess only single bonds in their chemical structure are called as saturated fatty acids. They are densely packed, which makes them solid at room temperature.
Example- Lauric acid ( present in coconut oil). It has 12 carbon atoms in its chemical structure.
All the nerve processes radiating out beyond the brain and spinal cord, as well as all the neurons outside the brain and spinal cord, constitute the peripheral nervous system.
Spinal cord is the backbone present in the vertebrates. It is essential for the correct posture and erect body. It extends from the end of the brain till the hipbone. The spinal cord consists of total 5 types of bones called vertebrae, that are total 33 in number.
Peripheral nervous system consists of parts of nervous system outside the brain and the spinal cord. It involves cranial and spinal nerves and their roots and branches, peripheral nerves, and neuromuscular junctions.

Answer:
This is the lytic cycle.
Explanation:
The lytic cycle is one of the two cycles of viral reproduction, the other being the lysogenic cycle. The lytic cycle results in the destruction of the infected cell and its membrane. Bacteriophages that only use the lytic cycle are called virulent phages. It is a type of viral reproduction.
