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 1

Answer:

You are very correct the answer is c

Answer 2

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.

How can offspring be created that have a specific phenotype and genotype?

Answers

Explanation:

The two things a Punnett square can tell you are the genotypes and phenotypes of the offspring. A genotype is the genetic makeup of the organism. This is shown by the three genetic conditions described earlier (BB, Bb, bb). The phenotype is the trait those genes express. But when it comes to  apperences, a phenotype is an individual's observable traits, such as height, eye color, and blood type. The genetic contribution to the phenotype is called the genotype. Some traits are largely determined by the genotype, while other traits are largely determined by environmental factors.

Which of the following characteristics do homologous chromosomes exhibit?.

Answers

Homologous chromosomes carry alleles of the same traits and therefore, carry the genetic information for the same trait.

Homologous chromosomes are a pair of chromosomes with the same gene sequence but of different origins - one paternal and the other maternal.

Thus, homologous chromosomes carry the same traits, although could be of different forms. For example, one of the chromosomes might carry a gene for tallness while the other might carry a gene for shortness even though both tallness/shortness represent a gene for height.

a cockroach is a fast-moving insect. how can an animal with an open circulatory system be so speedy?

Answers

Cockroaches have 6 legs and each leg has 3 knees, 18 knees in total. Since the cockroach has so many joints in its legs its can accurately pick up speed when running away from something

An animal like a cockroach with an open circulatory system is so speedy because in these organisms tracheal system delivers oxygen throughout the body.

What is an Open circulatory system?

An open circulatory system may be characterized as a type of circulatory system in which blood vessels are completely absent and blood generally flows freely through the cavities of the body. This type of circulatory system is present in arthropods.

Due to the absence of blood vessels, the flow of blood is extremely high in animals that have an open circulatory system. Apart from this, in cockroaches, oxygen is carried out through the tracheal system because of the absence of the lungs. So, it makes the process so speedy.

Therefore, an animal like a cockroach with an open circulatory system is so speedy because in these organisms tracheal system delivers oxygen throughout the body.

The anterior rami of spinal nerves ______ are called intercostal nerves because they travel in the intercostal space sandwiched between ______.

Answers

Answer: T1-T11; two adjacent ribs

Explanation:

The anterior rami of spinal nerves T₁ - T₁₁ are called intercostal nerves because they travel in the intercostal space sandwiched between two adjacent ribs.

What are the rami of spinal nerves?A typical spinal nerve typically branches out into rami as soon as it exits the intervertebral foramen.The smallest of the two main branches is the posterior (dorsal) ramus. It innervates the skin of the back as well as the deep muscles of the back, such as the transversospinalis and erector spinae. The bigger of the two main branches is the anterior (ventral) ramus. The anterior ramus divides into numerous additional branches that innervate the upper limbs, lower limbs, and anterior and lateral regions of the trunk. Numerous anterior rami develop into nerve plexuses.

Within cells, the long strands of DNA form condensed structures called chromosomes. Organisms inherit genetic material from their parents in the form of homologous chromosomes, containing a unique combination of DNA sequences that code for genes. cell nucleus
DNA is the hereditary material in humans and almost all other organisms. Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA). DNA contains the code for building and maintaining an organism.

Answer:

The structure that is responsible for the governance of a cell is the DNA, which is located in the nucleus of the cell.

Explanation:

DNA: It is the genetic material containing genetic information.It is present in the chromosomes inside the nucleus. The genetic information of DNA is stored as code in the four nucleobases namely Adenine, Guanine, Cytosine, and Thymine. The most unique feature of the DNA is that it is self-replicated and makes similar copies of itself. DNA is a double helical structure found in all living organisms including some viruses.In Eukaryotes along with the nucleus, DNA is also present in Mitochondria and Chloroplasts.
