The anwser should be B. Nonrenewable resources generally have a higher impact on the environmental than renewable resources.
Answer: C
Explanation: All organisms someway somehow must compete for essential resources.
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)
Answer: There are two main types of UAVs used for remote sensing applications: fixed-wing and rotary wing.
Please mark me as Brainliest
Hope this helps :)
Its internal mainly because none of the other words fit and because what happens with the rumbling and vomitting its INTERNAL
hope this helped plz mark brainliest if u can
