Hello!
The amount of water in a river varies for each particular area. Whether the area has been receiving rainfall or a drought.
Seasons also play a role; if it's Spring, you may receive more rainfall and have a higher water levels. If it's Summer, you may experience a drought, causing lower water levels.
Although that was not very much information, I thought I'd provide a small bit of information. Hope it helps. :)
The gasoline engine where the air and fuel mixture is burned is called the combustion chamber. A piston is used to increase and decrease the volume which prepares the fuel to be mixed with air. A spark plug is ignited then to create the combustion thereafter.
If the same protein keeps being produced it could be said that nothing is happening even though something happened, and if nothing is changing you could say that it is a silent mutation, which means that the answer is C.) Silent. The change in the amino acids and the nucleotides happened but it is silent and does not affect the outcome of the protein synthesis.
<span>Apocrine sweat glands release sweat into hair follicles. Unlike the more common eccrine sweat glands, these are found only in the armpits, anogenital region, ears and eyelids of humans. Unlike eccrine sweat, apocrine sweat doesn't really contribute to cooling the body. Apocrine sweat contains more chemical compounds than eccrine sweat; these feed bacteria on the skin which produce a detectable odor. Apocrine sweat glands become active at puberty and are most active in times of stress and sexual excitement.</span>
