Natural Selection is: CORRECT ANSWER a process leading to differential reproductive successes among members of a population Cactus-like plants adapted for desert or dry environments are succulent (have fleshy, juicy stems) and have spines (modified leaves). Succulents can be found to occur around the world, but are classified into a number of very different families of plants based on other characteristics. That so many different kinds of succulents exist is an example of: CORRECT ANSWER conv...

Binghamton Bio 114 Exam 2 Questions and Answers Already Passed Genetic Drift Refers to the ongoing variation in allele frequencies within a population over time due to random mating events. Genetic drift causes allele frequencies to fluctuate randomly. Random Mating Influences allele frequencies by altering how often specific alleles appear within a population. This process is inherently unpredictable, with allele frequencies increasing or decreasing randomly. Bottlenecks O...
