<span> A virus is not a living thing so antibiotics, intended to kill living things, are not effective. A virus cannot multiply outside a living host cell. There is no treatment for a virus, just supportive therapy. The body will fight off most viruses over the course of time. Vaccines do not cure viruses, so the only way to protect your goat from viruses is through specific vaccines.
So the answer is a virus</span>
The substance that helps keep the integrity of the bacterial cell wall intact is known as the peptidoglycan. Others also refer to is it as murein or mucopeptide. The bacterial cell wall is necessary for survival because of the high internal pressure present inside of bacteria. Under normal conditions, if the cell wall is removed the bacterial cell will burst.
The peptidoglycan is a layer that can be used to distinguish gram positive bacteria from gram negative ones. G(+) bacteria have a thick layer of this while G(-) have a thinner ones.
Concentrations of this toxin are found in the ant as well as in the lizard and the bird, as they are part of the same food chain. The lizard eats ants and the bird eats the lizard. This phenomenon is called biomagnification.
Biomagnification refers to the cumulative increase in concentrations of a persistent substance as one moves up the food chain (trophic chain).
Biomagnification is therefore a process in which the concentration of a substance present in a biotope increases throughout a food chain; by extension, the result of this process.
Answer:
Males are affected more because they only have one X chromosome, The abnormal gene responsible for hemophilia is carried on the X chromosome. Females on the other hand have two X chromosomes, and are therefore less likely to have it.

Answer:
The difference between a renewable and a non-renewable natural resource is whether or not the resource can be replaced.
Explanation:
Natural resources are those useful for human beings and for that reason are consumed by them.
Renewable natural resources —such as water, plants and trees or solar energy— are usually renewed at a rate greater than or equal to their consumption, so they are not depleted.
A non-renewable natural resource, such as petroleum, usually has a limited existence, or its renewal speed is very slow, so its consumption can decrease its quantity or deplete it.
The difference between renewable and non-renewable resources is in their long-term availability or depletion.
Other options are not correct because:
- <em>Both types of resources exist in nature.
</em>
- <em>Both resources can decrease, but one is renewable and the other can be depleted.
</em>
- <em>Both renewable and non-renewable resources are useful for humans.</em>
