The pKa of an acid depends partly on its environment. Predict the effect of each of the following environmental changes on the p
Galina-37 [17]
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)

While taking a walk around the neighborhood, a student walks into a tree branch and cuts their arm. Which explanation BEST descr
DaniilM [7]

Answer:

C

Explanation:

First off, humans are considered animals, and since animal cells don't have chloroplasts, A and D are immediately incorrect. B is incorrect because lysosomes eject enzymes that digest materials in the cell, and to heal skin, you dont need to digest anything/ use enzymes to get rid if materials. That means the answer is C. The nucleus is the control center for the cell, so it tells the cell what to do. The mitochondria creates energy for the cell, and since it takes energy to heal, this answer is correct. (Tip- I find that using process of elimination in biology questions helps a lot.) Good luck!

Sometimes a suffix functions independently as a medical term. give two examples of suffixes that are also terms, and explain how
aleksandrvk [35]

The answer would be –genesis and –gram. 

Suffixes that have a Greek or Latin roots and that are used to combine with other words or parts of words are not called suffixes, these kind of affixes are called combining forms.


One combing form is –genesis.


As an independent medical term, this means the origin of something in medicine. When a doctor talks about the genesis of a contagion, he or she is speaking of the point of origin of a contagion.


-genesis used as a suffix, can indicate a particular process or pathogen. Example is parthenogenesis.


One combining form is –gram.


As an independent medical term, gram indicated the metric weight of an object as a unit of mass. If nurses talk about how much serving of food, they are talking about it in grams.

-gram signifies something written down. Example is pictogram.
