Explain the water cycle using the terms condensation, evaporation, and precipitation.
RideAnS [48]

Answer:

The water cycle is also known as the hydrological cycle. It shows how water is circulated continuously within the atmosphere of the Earth.

Evaporation is the process where water, when heated, goes from the liquid to gaseous state in the form of vapor. This is how water gets from the geosphere to the atmosphere. As the vapor rises, the air around it gets cooler, and this is where condensation occurs. Condensation is the process where vapour will turn into its liquid state. As more vapour condense they start to form clouds. When the cloud gets dense enough, the water falls back to Earth through precipitation.

There are 100 cats in a population that follows hardy-weinberg conditions. 4 cats display a recessive white coat color. how many
mr Goodwill [35]

We know that Hardy-Weinberg conditions include the following equations:


p^{2}+2pq+ q^{2}=1


where p+q=1


And where p = dominant, and q = recessive; this means that p^{2} is equal to the homozygous dominant, 2pq is the heterozygous, and q^{2} is the homozygous recessive .


So we have 100 total cats, with 4 having the recessive white coat color. That means we have a ratio of \frac{4}{100} or 0.04. Let that equal our q^{2} value.


So when we solve for q, we get:


q^{2}=0.04

q=\sqrt{0.04} =0.2


Now that we have our q value, we can use the other equation to find p:


p+q=1


p+0.2=1


p=0.8


So then we can solve for our heterozygous population:


2pq=2(0.8)(0.2)=0.32


This is the ratio of the population. So we then multiply this number by 100 to get the number of cats that are heterozygous:


0.32*100=32cats


So now we know that there are 32 heterozygous cats in the population.

A(n) ____________ is a preparation of one or more microbial antigens to induce protective immunity in potential hosts. listen to
Dmitry [639]

A vaccine is a preparation of one or more microbial antigens to induce protective immunity in potential hosts.

Vaccines are the anti-microbial agents administered to provide immunity against specific diseases. There can be a wide variety of vaccines, like: live attenuated vaccine, vaccine with killed or inactivated microbes, vaccine containing the sub-parts of the microbes, etc.

Immunity is the body's ability fight against a disease. The immunity is build when a body gets attacked by pathogen. Various immune cells like neutrophils, MHCs, dendritic cells, B and T cells, etc. are involved in building and strengthening the immunity of any person.
