Answer:

Antibiotics are strong medicines that treat bacterial infections. Antibiotics won't treat viral infections because they can't kill viruses.

You'll get better when the viral infection has run its course. Common illnesses caused by bacteria are urinary tract infections, strep throat, and some pneumonia.

How biodiversity is affected by speciation, disruptive, stabilizing, and directional selection?
VikaD [51]

There are several ways selection can affect population variation:

stabilizing selection

directional selection

diversifying selection

frequency-dependent selection

sexual selection

As natural selection influences the allele frequencies in a population, individuals can either become more or less genetically similar and the phenotypes displayed can become more similar or more disparate. In the end, natural selection cannot produce perfect organisms from scratch, it can only generate populations that are better adapted to survive and successfully reproduce in their environments through the aforementioned selections.

When the acetyl-CoA produced during -oxidation in the liver exceeds the capacity of the citric acid cycle, the excess acetyl-Co
Oliga [24]

Answer:

There is a need to transform the accumulation of acetyl-CoA into the ketone bodies, as one knows that acetyl-CoA is both labile and possess an enormous amount of energy. Hence, acetyl-CoA due to its unstable characteristic is not ideal for circulation within the tissues, and at the same time, the compound acetyl-CoA does not possess the tendency to pass through the cell membrane.  

Due to these reasons, the conversion of acetyl-CoA into the ketone bodies is done, the ketone bodies also act as an alternative source of energy. The ketone bodies work as water-soluble correspondents of fatty acids. The production of ketone bodies generally takes place within the liver cells' mitochondrial matrix. The three forms of ketone bodies are beta-hydroxybutyrate, acetoacetate, and acetone.  

The production of ketone bodies by the liver cells helps the cells of the brain at the time of starvation, as the brain cannot use fatty acids as an energy source, as the fatty acids cannot pass through the blood-brain barrier.

The table shows the relative size of the genomes (total DNA in the nucleus), number of genes, and number of chromosomes for a va
9966 [12]
You don't show the table...but you should see that the more complex an organism, the more chromosomes and the more genes it has.

A bacteria has a small genome. perhaps it has about 5000 genes. it also has 1 chromosome.

Yeast are more complicated than bacteria. Saccharomyces cerevisiae (the yeast that makes beer, wine and bread, has about 6300 genes and 16 chromosomes.

A human has 46 chromosomes (23 pairs), and has likely around 20,000 genes.
