Ques: Q: What is the term for a theoretical framework for describing evolutionary change in populations through the change in allele frequencies? Read this paragraph and choose the correct option from the provided answers: CHAPTER SUMMARY 11.1 Discovering How Populations Change Evolution by natural selection arises from three conditions: individuals within a species vary, some of those variations are heritable, and organisms have more offspring than resources can support. The consequence is that individuals with relatively advantageous variations will be more likely to survive and have higher reproductive rates than those individuals with different traits. The advantageous traits will be passed on to offspring in greater proportion. Thus, the trait will have higher representation in the next and subsequent generations leading to genetic change in the population. The modern synthesis of evolutionary theory grew out of the reconciliation of Darwin's, Wallace's, and Mendel's thoughts on evolution and heredity. Population genetics is a theoretical framework for describing evolutionary change in populations through the change in allele frequencies. Population genetics defines evolution as a change in allele frequency over generations. In the absence of evolutionary forces allele frequencies will not change in a population; this is known as Hardy-Weinberg equilibrium principle. However, in all populations, mutation, natural selection, genetic drift, and migration act to change allele frequencies. Choices: - percent genetics - density genetics - total genetics - population genetics A:
Ans: population genetics

Ques: Q: Myopia is commonly called what? Read this paragraph and choose the correct option from the provided answers: Myopia is commonly called nearsightedness. People with myopia can see nearby objects clearly, but distant objects appear blurry. Myopia occurs when images focus in front of the retina because the eyeball is too long. This vision problem can be corrected with concave lenses, which curve inward. The lenses focus images correctly on the retina. Choices: - farsightedness - blindness - scoliosis - nearsightedness A:
Ans: nearsightedness

Ques: Q: When do homologous chromosomes form pairs? Read this paragraph and choose the correct option from the provided answers: When homologous chromosomes form pairs during prophase I of meiosis I, crossing-over can occur. Crossing-over is the exchange of genetic material between non-sister chromatids of homologous chromosomes. It results in new combinations of genes on each chromosome. Choices: - mitosis - metathesis - transcripton - meiosis A:
Ans: meiosis

Ques: Q: What is the term for the change in temperature with distance? Read this paragraph and choose the correct option from the provided answers: Temperature gradient is the change in temperature with distance. Choices: - heat gradient - distance gradient - temperature volatility - temperature gradient A:
Ans:
temperature gradient
