In this case, it is given that <em>Mycoplasma pneumoniae </em>lacks cell wall. some antibiotics such as penicillin works by interfering the synthesis of the cell walls. As these microbes do not have cell wall, the penicillin like antibiotics would not work.

In this case, the antibiotics, which interferes with the DNA (deoxyribonucleic acid) formation and replication can work. The ciproflaxin is an antibiotic, which work by inactivating the enzyme required for DNA replication in bacteria. Hence, the antibiotic ciproflaxin would be effective for treating the given condition.

which example of a missense mutation in a protein-encoding gene would most likely be a neutral mutation?
KATRIN_1 [288]

An example of a missense mutation in a protein-encoding gene would most likely be a neutral mutation is option B: replacement of a polar amino acid with another polar amino acid at the protein's surface.

A frequent and well-known example of a missense mutation is the blood condition sickle-cell anemia. Missense mutations exist in the DNA at a single location in sickle-cell anemia patients. A different amino acid is required in this missense mutation, which also alters the overall structure of the protein. Similarly, replacement of a polar amino acid by another polar Ami no acid at the protein's surface is a missense mutation causing change in a single site.

A neutral mutation is one whose fixation is unrelated to natural selection. Therefore, the independence of a mutation's fixation from natural selection can be used to define the selective neutrality of a mutation.

Complete question is:

Which example of a missense mutation in a protein-encoding gene would most likely be a neutral mutation?

a) Replacement of a polar amino acid with a nonpolar amino acid at the protein's outer surface

b) Replacement of a polar amino acid with another polar amino acid at the protein's surface

c) Replacement of a polar amino acid with another polar amino acid in the protein's interior

d) Replacement of a polar amino acid with a nonpolar amino acid in the protein's interior

Why do individuals who suffer from brainstem injuries have difficulty with their autonomic functions?
scoundrel [369]

Answer: The brainstem controls autonomic functions through cranial nerves arising from it, along with the medulla oblongata, therefore an injury to the area can cause loss of these functions.

Explanation:

The brainstem comprises of the midbrain, and the pons and medulla of the hindbrain. It is in direct continuation with the spinal cord. Ten cranial nerves arise from this part, and a number of tracts pass through this region. The medulla of the brainstem are particularly involved in maintaining heart rate, breathing and blood pressure. In case of a brainstem injury, the cranial nerves responsible for autonomic functions could get damaged leading to dysfunction and/or the areas of medulla consisting of centres controlling heart rate, blood pressure or other autonomic functions, if damaged could cause difficulties.

Helga [31]

Answer:

<em>Jansky Very Large Array </em>

Explanation:

It Is most powerful telescope on Earth and  is located on the plains of San Agustin near Socorro, New Mexico, US. This telescope consist of 25 antennas whose collective ares is equal to a single 430 foot antenna. The angular resolution is equal to an antenna of 22 miles in diameter.  It is also possible to adjust its arms to change its resolutions. There is receiver in each antenna that can operate from wavelength range of 4 mm to 7 metres. National Radio Astronomy Observatory is in charge of this telescope.
