Answer:
is that sediment is a collection of small particles, particularly dirt, that precipitates from a river or other body of water while silt is mud or fine earth deposited from running or standing water.....Sedimentary rocks can contain fossils because, unlike most igneous and metamorphic rocks, they form at temperatures and pressures that do not destroy fossil remains.....Chemical sedimentary rocks form by precipitation of minerals from water. Precipitation is when dissolved materials come out of water. For example: Take a glass of water and pour some salt (halite) into it. ... This is a common way for chemical sedimentary rocks to form and the rocks are commonly called evaporites.

Answer:
Primary visual cortex
Explanation:
The primary visual cortex is the part of the brain that enables the exercise of visual memory in a person.
The primary visual cortex is the part of the brain that enables the exercise of visual memory in a person. It is a type of memory that allows you to remember an image that has already disappeared from the senses. Damage to the primary visual cortex would result in an inability to identify and understand what is seen by the eyes, because it would damage a person's visual memory.

Answer:
In the given case, the homogeneity of the protein is done. By performing, the technique of gel-filtration chromatography, the mass of the protein obtained is 60 kilodalton. When the chromatography is performed in the existence of urea, a protein of mass 30 kilodalton is obtained. The ratio between the two obtained mass is 60/30 = 2, thus, it shows that the protein comprises two subunits and each of them weighs 30 kilodaltons.
When the same technique of chromatography is performed in the existence of beta-mercaptoethanol and urea, a single protein of mass 15 kilodalton is produced. Now, the ratio is 30/15 = 2. Therefore, each subunit of the protein comprises two units of mass 15 kilodalton.
Hence, it shows that the protein is a tetramer of 15 kilodalton subunits and each subunit produces dimers of mass 30 kilodalton and is attached by disulfide bonds.
