The answer would be the hardening of the myelin sheath. Multiple sclerosis is a chronic and inflammatory disease affecting the Central Nervous System and can cause a lot of symptoms like sensation changes, visual problems, severe fatigue and muscle weakness.

Answer:

The disease is caused mainly because of the attack on the myelin sheath by own immune system.

Explanation:

The MS or multiple sclerosis refers to a possibly disabling disorder of central nervous system. In the condition, immune system fights against and destroys the myelin, that is, the protective sheath, which envelopes the nerve fibers. This causes problems of communications between the brain and the entire part of the body. Ultimately, the disease can result in deterioration or permanent destruction of the nerves.

A period in 24-point font (.) is about 1mm in diameter. SARS-CoV-2 has a diameter of 80 nm. The prefix “milli” means 1000, which
Artist 52 [7]

Answer:

A total of 12,500 SARS-CoV-2 viruses

Explanation:

Consider a trillion against a thousand, there exists a difference of a million, which means a nanometer will be a million times smaller as compared to one millimeter:

see below for a milli  divided by nano

1/1000​  ÷  1/1000,000,000​  =  1000,000,000  ÷ 1000 =  1000,000

(in reference to the hint given in the question statement)

The question puts one millimeter against 80 nanometers. The calculation for this will be given as follows:

1/1000 ​  ÷  80/1000,000,000 =    1000,000,000 ÷ 80,000​  =  12,500  

According to the above working, there are 12,500 SARS-Cov-2 viruses thatg can fit into one period.

"the somatic and autonomic nervous systems are the two major divisions of the _____ nervous system."
Yuri [45]

Answer;

-Peripheral nervous system

-The somatic and autonomic nervous systems are the two major divisions of the peripheral nervous system.

Explanation;

-The nervous system can be divided into two major subdivisions: the central nervous system (CNS) and the peripheral nervous system (PNS). The peripheral nervous system is comprised of the somatic and autonomic nervous systems. The somatic nervous system transmits sensory and motor signals to and from the central nervous system.

-The somatic nervous system is involved in the relay of sensory and motor information to and from the CNS; therefore, it consists of motor neurons and sensory neurons. Motor neurons, carrying instructions from the CNS to the muscles, are efferent fibers.

-The autonomic nervous system controls our internal organs and glands and is generally considered to be outside the realm of voluntary control. It can be further subdivided into the sympathetic and parasympathetic division.

konstantin123 [22]

Answer:

The correct statements are that the first calorimeter is reliable but not valid, and the second calorimeter is valid and reliable.

Explanation:

The first calorimeter is reliable as the reading demonstrated by it is similar when each time the experiment is performed, however, the result attained is not correct, though it is reliable. On the other hand, the second calorimeter is both reliable and valid, as it is demonstrating the accurate results from time to time. This is valid as it is providing a similar result as that of the original readings.

A cat gives birth to kittens that do not resemble either parent, while a plant grown from a sapling is similar to its parent pla
Tomtit [17]

Answer:

The correct answer would be D) Kittens receive features from both parents but the plant offspring receives features from a single parent.

Cat only reproduces sexually in which male and female parent contribute equal genetic material to the offspring. It leads to the genetic variation in the offspring.

In addition, crossing over takes place during gametogenesis also adds to the genetic variation of the offspring produced by sexual reproduction.

This is the reason that kitten (offspring produced by sexual reproduction) has some genetic variations as compared to the parent and it does not resemble either of the parents.

In contrast, saplings can be done vegetatively through cutting due to saplings receive genetic material from a single parent.
