Suppose a human blood cell containing a 0.9 percent solute concentration were put into a container of 0 percent solute solution

Vladimir [108]

Answer and explanation:

If a human blood cell with a 0.9% solute concentration were to be put into a container of 0% solute solution, the cell would get BIGGER.

The cell contains a more concentrated solution than the solution in the container. The difference in concentration would produce an osmotic gradient that would cause water from the container to get inside the cell to even the concentrations - this is going to make the cell much bigger because the entering water would bloat the cell.

In this example, the solution in the container is hypotonic in relation to the cell, while the solution inside the cell is hypertonic in relation to the solution in the container. This is why the water will be moving from outside of the cell to the inside of the cell.

A protein biochemist attempted to determine the amino acid sequence of a decapeptide. Use the results from the trypsin, chymotry

Maksim231197 [3]

Answer:

The possible sequence of the decapeptide is Met-Val-Lys-Tyr-Thr-Trp-Ala-Arg-Pro-Phe.

Explanation:

The cyanogen bromide cleaves the carboxyl end of Met (methionine and non-peptide). Trypsin cleaves on the C-terminal of Arg and Lys, however, not on the N-terminal of Pro, which signifies that Lys is the last amino acid in T2. Hence, Met-Val-Lys----. The middle part of the sequence can be predicted from the digestion done by chymotrypsin.

The chymotrypsin cleaves on the C terminal of Phe, Trp, Tyr, however, not on the N side of Pro. CT3 exhibit Lys, Met, Tyr, Val, as Met-Val and Tyr are the initial three amino acids, therefore, Tyr must be the fourth one. Now the sequence will be Met-Val-Lys-Tyr...

CT1 possesses Ala, Arg, Phe, Pro, as chymotrypsin cleaves the C side of the Phe, thus, the last amino acid should be Phe. Also, CT1 has Ala as the first amino acid. Also, trypsin does not cleave on the N-end of Pro. Thus, the sequence of CT1 strands will be Ala-Arg-Pro-Phe.

In CT2, chymotrypsin cleaves on the C-side of trp. Thus, the sequence of CT2 strands as Thr-Trp is found in the middle. Thus, the whole sequence of the decapeptide strand will be:

Met-Val-Lys-Tyr-Thr-Trp-Ala-Arg-Pro-Phe.

ILL GIVE 60 POINTS AND A BRAINIEST

tigry1 [53]

Answer:

1. The school board wants to clear the forest surrounding the local high school to build more fields for high school sports. Following environmental factors need to be investigated before clearing the land:

1. Destruction of natural ecosystem: As forest will be cut the land will be barren. There will be loss , extinction and migration of faunal species. So, the normal balance of ecosystem will b disturbed.

2. Chances of climatic fluctuations: As, forest will be cleared, the water, carbon and oxygen cycle in the atmosphere will be disturbed. The region may not acquire adequate rainfall, temperature of the area will change drastically.

3. Soil erosion: As, forest will be cleared the soil will not be hold up and the loose soil gets wiped out from the location by water or air.The cutting of trees can cause flooding from nearby water body.

2. Two ways to reduce air pollution and slow climatic change are:

1. Control use of fossil fuels: Fossil fuels like coal, petrol, kerosene are used in automobiles, industries and house hold activities. These fossil fuels are organic in nature and adds up carbon dioxide, carbon monoxide, nitrogen dioxide gases in air and raises the atmospheric temperature and are responsible for air pollution. Therefore, the use of fossil fuel should be in control manner.

2. Planting more number of trees: The trees are responsible for fixing atmospheric carbon from air for photosynthesis. So, they can decrease the amount of atmospheric carbon abundantly present in forms of carbon dioxide and carbon monoxide, which are chief air pollutants. These carbon products are responsible for raising temperature so planting of trees can prevent raise of temperature.
