~OH 5 p-toluenesulfonic acid pKa ~7 TsOH OH acetic acid pKa 4.8 The Correct Answer and Explanation is: Correct Answer: Acetic acid (pKa ≈ 4.8) is a stronger acid than p-toluenesulfonic acid (TsOH, pKa ≈ 7). Explanation: The pKa value of an acid measures its tendency to donate protons (H⁺). A lower pKa value corresponds

Amoeba Sisters Video Recap: Genetic Drift Populations can have variety, despite being made up of the same species. If a population has different expressed traits, this can be due to different inherited alleles. Genetic drift can cause a change in allele frequency in a population. What if you had to explain genetic drift to a

simplest form with solution!1. 1/3 × 2 1/4 The Correct Answer and Explanation is: Answer: 13×214=13×94=912=34\frac{1}{3} \times 2\frac{1}{4} = \frac{1}{3} \times \frac{9}{4} = \frac{9}{12} = \frac{3}{4}31​×241​=31​×49​=129​=43​ Explanation: To solve the expression 13×214\frac{1}{3} \times 2\frac{1}{4}31​×241​, first convert the mixed number 2142\frac{1}{4}241​ into an improper fraction. A mixed number contains both a whole number and a fraction.
