What is herd immunity, and why are vaccines important for achieving herd immunity?

Biology
1 answer:
kap26 [50]3 years ago
8 0

Answer:

Herd immunity is a form of indirect protection from infectious disease that can occur with some diseases when a sufficient percentage of a population has become immune to an infection, whether through vaccination or previous infections, thereby reducing the likelihood of infection for individuals who lack immunity.

Explanation:

Vaccines create immunity without causing illness or resulting complications. Herd immunity makes it possible to protect the population from a disease, including those who can't be vaccinated, such as newborns or those who have compromised immune systems.

It is often stated that the phosphate bonds in atp are "high energy," but in fact, they are not notably high in energy. rather,
Vera_Pavlovna [14]

The answer is Negative charges on phosphate groups repel each other. The oxygen groups of a phosphoanhydride in ATP have electron cloud that repels each other. On hydrolysis, once a phosphate is lost, the electrostatic repulsion is reduced.

When ATP is hydrolyzed, it forms more hydrogen bonds with surrounding water molecules that when ATP is unhydrolyzed. Therefore, more energy is released since more bonds are formed than are broken. The net delta G is positive during hydrolysis of ATP.

Under which of the following conditions is a on most likely no evolve abimodaldistribution? o selection favors muniple distinct
iogann1982 [59]

Answer:

The correct answer is "selection favors multiple distinct trait values, and similar individuals tend to mate with each other".

Explanation:

A population with a bimodal distribution are groups of organisms with two major traits or "modes", with practically equal amounts of individuals with these two modes. This type of distributions indicate that the population is not homogenous and that more than one trait is favored in the given circumstances. A bimodal distribution is most likely to evolve when selection favors multiple distinct trait values, and similar individuals tend to mate with each other. In this case natural selection favors more than one value, and due to the individuals with one value tend to mate to each other, only two major traits are favored in the population.
