<span>I believe the answer is A. hydrophobic. Inside the biological membranes are lipids (hydrophobic) molecules. As you may know the membranes are lipid bilayers. In order to place proteins, which are polymers of amino acids, you would need to create an like-to-like environment. The R groups of amino acids will interact with this hydrophobic lipid bilayer environment and will need to display the same characteristics to keep the plasma membrane intact and not cause unwanted disruption. Therefore, R groups of amino acids in biological membranes should be hydrophobic. </span>
Answer:
Because lack of carbon dioxide causes the lack of acidic HCO₃⁻ which help to the regulation of the blood's pH.
Explanation:
Hello.
In this case, since the presence of carbon dioxide in blood regulates the pH of blood by maintaining it at about 7.35 to 7.45 (slightly basic) due to the equilibrium shown on the attached picture by which the yielded HCO₃⁻ ions low down the pH because the lack of CO₂ cause a condition known as respiratory alkalosis in which the pH of the blood significantly increases.
Thus, that condition causes symptoms such as confusion, hand tremor, lightheadedness., muscle twitching, nausea, vomiting and others.
