Why are common cold viruses difficult to cure?(1 point)

A copy of the DNA is made from the viral RNA.

The virus leads to other viral infections such as the flu and HIV.

The viral genome mutates very quickly.

Vaccines prevent the development of a cure.

Answers

Answer:

You are very correct the answer is c

Correct option is ''The viral genome mutates very quickly.''

Viruses can't reproduce on their own as bacteria do, instead, they attach themselves to healthy cells and reprogram those cells to make new viruses. It is because of all of these differences that antibiotics don't work on viruses. Antibiotics and medications treat bacterial infections. These antibiotics cannot treat or cure a common cold as colds aren't caused by bacteria.

Common cold viruses are difficult to cure as the viral genome mutates very quickly.

what will happen if phase changes didn't exist?​

Answers

Answer:

Matter can exist in one of several different states, including a gas, liquid, or solid state. The amount of energy in molecules of matter determines the state of matter.

A gas is a state of matter in which atoms or molecules have enough energy to move freely. The molecules come into contact with one another only when they randomly collide.

A liquid is a state of matter in which atoms or molecules are constantly in contact but have enough energy to keep changing positions relative to one another.

A solid is a state of matter in which atoms or molecules do not have enough energy to move. They are constantly in contact and in fixed positions relative to one another.

Answers

Answer:

Hey, your answer should be D

Explanation:

Good luck friends

The researcher who theorized that hypnosis comes about as a form of roleplay between hypnotist and subject is Milton Erickson, who is in Option D. Milton Erickson was a famous American psychiatrist and psychotherapist.

What is Milton Erickson?

He is widely known for his pioneering work in the field of hypnosis. He believed that hypnosis is a form of communication between the hypnotist and the subject and that it involves a process of "roleplay" in which both parties take on certain roles or identities. In this sense, the hypnotist takes on the role of a facilitator or guide, helping the subject access their own inner resources and abilities. The subject, on the other hand, takes on the role of an active participant in the hypnotic process, using their own imagination and creativity to bring about positive changes in their thoughts, feelings, and behaviors.

Hence, the researcher who theorized that hypnosis comes about as a form of roleplay between hypnotist and subject is Milton Erickson, who is in Option D.

there are about one million nephrons in one kidney which are responsible for urine formation

The microscopic filtering units found in the kidneys that are responsible for urine formation are called nephrons, so here the correct option is option a.

Throughout the nephron, various processes such as filtration, reabsorption, and secretion occur to produce urine. Filtration occurs at the glomerulus, where water and small solutes are forced out of the blood into the Bowman's capsule. Reabsorption involves the selective reabsorption of water, ions, and nutrients from the filtrate back into the bloodstream. Secretion involves the active transport of waste products, excess ions, and toxins from the bloodstream into the filtrate. So here, the correct option is option a.
