B. a desert in southern Texas. In heat sound waves travel faster because the heat gives them more energy which allows them to vibrate faster.
Answer: polyunsaturated fatty acid residues
Explanation: Unsaturated fatty acids have a lower melting point so arctic animals have these fatty acids in their membranes.
A buffer is a solution encompassing a weak acid and its conjugate base in alike amounts. This combination reduces the pH change upon addition of strong acid or base by converting H1+ (or OH1-) to weaker acids or bases. This primarily consist of compounds that stabilize the pH of a solution by removing or replacing hydrogen ions. Also, substances that resist change in pH.
Species is the most narrow category

answer is allelic frequency. This is also the fraction
of a particular allele of a gene in the population. Allelic
frequency in a population of diploid individuals is calculated using the Hardy Weinberg equation
of p2 + 2pq + q2 = 1. Allelic frequency of all the alleles of the genes must add up to 1 (one).</span>
