Answer:
What does even EATLING mean.
Is it eating?
The pKa represents the pH of the medium at which the zwitterionic amino acid assumes most stable ionic form due to structural stabilization. As the pKa is dependent upon the environmental factors of the solution around the amino acids, a change in their structure and localization can cause change in the pKa of the protein. Thus, the answers can be found as below:
Part A: Decrease (As the lysine is basic in nature, it will tend to stabilize the electrostatic interaction and weak interactions between the acidic amino acids and hydrogen bonds in the viscinity, thus lowering the pH and hence pKa of the protein)
Part B: Increase (As the carboxyl group is acidic in nature, removal of it will tend to increase the pKa since the basic amino acids will tend to accumulate more negative charge in their viscinity)
Part C: Increase (As glutamic acid is an acidic amino acid, its shift from outside to a non-polar site will prevents its ionization and hence the pKa will tend to shift from slightly acidic to slightly basic, hence increase)
The right option is; d. Immune system
The immune system is responsible for defending the body against harmful substances.
The immune system is the body’s defense system that protects the body against infectious pathogens and other invaders. The immune system is composed of many biological structures (special cells, proteins, tissues, and organs) and processes that functions together to protect the body. White blood cells are one of the important cells of the immune system that destroy harmful substances or disease-causing organisms that invade body systems.
Ecological succession provides diversity and depth to a biotic community. Without it, life can not grow or progress. ... ( I don’t know if this will help you but here you go. )
Answer: So basically we have to know does the material's characteristics/compositions affect its density?
Explanation: Density is defined as the ratio of the mass of a material to its volume at a specific temperature and pressure. The Density of material is changed by changing its mass to volume ratio or by changing its temperature or by changing its pressure, the density of material changes. The Density of material is changed by changing its mass to volume ratio or by changing its temperature or by changing its pressure, the density of material changes. From the above description, it can be inferred that a material's composition or chemical characteristics may remain unchanged if density changes by changing the pressure or temperature of the material.
