Answer:
B. Students' ACCUPLACER scores might indicate that they need to
develop certain skills before enrolling in college-level coursework.
Explanation:
If the process of genetic drift was the cause of this phenomenon, then the resistance allele was also present in the original farm.
<h3>What is genetic drift?</h3>
Genetic drift is a genetic phenomenon that occurs when one allele is fixed in a population due to random chance.
Genetic drift is converse to natural selection, where an allele increases this frequency due to evolutionary constraints.
Genetic drift is well known to be the cause of allele fixation by founder population effects.

Answer
Jaime is preparing for a bicycle race. His goal is to bicycle an average of at least 280 miles per week for 4 weeks. He bicycled 240 miles the first week, 310 miles the second week, and 320 miles the third week. Which inequality can be used to represent the number of miles, x, Jaime could bicycle on the 4th week to meet his goal?
Solution
Jaime’s goal is to average at least 280 miles per week for 4 weeks. If T is the total number of miles Jamie will bicycle for 4 weeks, then his goal can be represented symbolically by the inequality:T⁄4, or equivalently T ≥ 4(280). The total number of miles Jamie will bicycle during this time is the sum of the distances he has completed and has yet to complete. Thus T = 240 + 310 + 320 + x. Substituting this expression into the inequality T ≥ 4(280) gives 240 + 310 + 320 + x ≥ 4(280). Therefore, choice D is the correct answer.
Choices A, B, and C are incorrect because they do not correctly capture the relationships between the total number of miles Jaime will ride his bicycle (240 + 310 + 320 + x) and the minimum number of miles he is attempting to bicycle for the four weeks (280 + 280 + 280 + 280).
