Answer:

Overall charge on protein becomes increasingly positive as pH decreases while overall charge on protein becomes negative as pH increases.

Explanation:

It is noticeable that protein are made up of amino acids which contain amine and Carboxyl functional groups.

Protein molecules in aqueous solution become positively charged (Protonated) as pH drops because of the fact that carboxylic acids become less negatively charged as the pH goes on to drop while amine become more positively charged.

Whereas overall charge on protein becomes more negative as pH increases because Acidic groups become more negatively charged while the basic group become less positively charged.

I think it’s microbiology, since it would help the student understand the process of composting the best. Botany is plants- not for composting. Geophysics- he’s not researching tectonic plates. Oceanography- he isn’t interested in the marina trench

The following question appears on a quiz: ""You fill a tank with gas at 60°C to 100 kPa and seal it. You decrease the temperatu
dusya [7]

Answer: The final pressure will decrease ad the value is 85 kPa

Explanation:

To calculate the final pressure of the system, we use the equation given by Gay-Lussac Law. This law states that pressure of the gas is directly proportional to the temperature of the gas at constant pressure.

Mathematically,

\frac{P_1}{T_1}=\frac{P_2}{T_2}

where,

P_1\text{ and }T_1 are the initial pressure and temperature of the gas.

P_2\text{ and }T_2 are the final pressure and temperature of the gas.

We are given:

P_1=100kPa\\T_1=60^0C=(60+273)K=333K\\P_2=?\\T_2=10^0C=(10+273)K=283K

Putting values in above equation, we get:

\frac{100kPa}{333K}=\frac{P_2}{283K}\\\\P_2=85kPa

Hence, the final pressure will decrease ad the value is 85 kPa
