Q: Answer the following question given this paragraph: 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. Q: What is the term for a theoretical framework for describing evolutionary change in populations through the change in allele frequencies? A:

OPTIONS:
- percent genetics
- density genetics
- total genetics
- population genetics

A: population genetics

Answer the following question given this paragraph: When a colorless solution of lead(II) nitrate is added to a colorless solution of potassium iodide, a yellow solid called a precipitate is instantly produced ( Figure below ). A precipitate is a solid product that forms from a reaction and settles out of a liquid mixture. The formation of a precipitate may also indicate the occurrence of a chemical reaction. Q: What is produced when a colorless solution of lead nitrate is added to a colorless solution of potassium iodide? A:

OPTIONS:
- blue solid precipitate
- brown solid precipitate
- purple solid precipitate
- yellow solid precipitate

Answer: yellow solid precipitate
