What is a good strategy for helping to prevent the spread of antibiotic resistance?
Flauer [41]

Answer:

Taking antibiotics only on doctor prescription and completing the full course of antibiotics.

Explanation:

Antibiotic resistance occurs when bacteria do not get harmed or killed by a drug which is made against them. Misuse and overuse of antibiotics are the main culprits which induce antibiotic resistance in bacteria.

To prevent the spreading of antibiotic-resistant bacteria antibiotics should only be taken on doctor's prescription. Full course of antibiotics should be done to eliminate all the bacteria which ensures that no bacteria is left to gain antibiotic resistance against the drug.

Antibiotics do not affect or kill virus therefore they should not be taken in viral infection.

Explain how prokaryotes can reproduce sexually and asexually.  In this discussion be sure to explain how the genetic material fr
Alexxx [7]

Answer:

During the asexual reproduction, bacteria can divide simply by binary fission in which one bacteria first replicate its genetic material and the cell divide in two daughter cells which are identical to the parent cell.

Asexual reproduction does not allow genetic variation therefore to get genetic variation bacteria can use conjugation, transformation and transduction process.

In conjugation, bacteria gets extra genetic material from other bacteria through sex pills. In transduction the genetic material enters into the bacterial cell through the virus then bacteria incorporate this genetic material in its genome.

In transformation, bacteria takes up the extra genetic material from it's surrounding. Therefore conjugation, transduction, and transformation helps bacterial to gain variation like as in sexual reproduction.

The production of red blood cells is regulated by a feedback loop involving erythropoietin. In non-disease states, the productio
LuckyWell [14K]

Answer:

Negative feedback.

Explanation:

The production of erythropoietin by the liver and kidneys is a negative feedback because with the production of erythropoietin, our body tends to move to become more stable state. The erythropoietin is produced by the liver and kidneys to increase the production of red blood cells if the quantity of red blood cells are lower than the normal range. If the number of red blood cells are decreases the oxygen level in our body is low that leads to unstable condition of the body but when the concentration of red blood cells increases, the body move towards stability.
