Answer the following question given this paragraph: Volcanoes at divergent plate boundaries are in the East Pacific Rise. Convergent plate boundaries, where there are trenches, have volcanoes. Hotspot volcanoes are in chains in the middle of the ocean basin. Q: What do convergent plate boundaries with trenches have? A:

OPTIONS:
- geysers

Answer: volcanoes

Problem: OPTIONS:
- reproduction
- apoptosis
- meiosis
- mitosis
Q: Answer the following question given this paragraph: The first and longest phase of mitosis is prophase . During prophase, chromatin condenses into chromosomes, and the nuclear envelope, or membrane, breaks down. In animal cells, the centrioles near the nucleus begin to separate and move to opposite poles of the cell. As the centrioles move, a spindle starts to form between them. The spindle, shown in Figure below , consists of fibers made of microtubules. Q: Chromatin condenses into chromosomes during prophase, the first and longest phase of what process? A:
Answer: mitosis

Problem:OPTIONS:
- same selection
- artificial selection
- characteristic selection
- natural selection

Answer the following question given this paragraph: 19.2 Population Genetics Both genetic and environmental factors can cause phenotypic variation in a population. Different alleles can confer different phenotypes, and different environments can also cause individuals to look or act differently. Only those differences encoded in an individual's genes, however, can be passed to its offspring and, thus, be a target of natural selection. Natural selection works by selecting for alleles that confer beneficial traits or behaviors, while selecting against those for deleterious qualities. Genetic drift stems from the chance occurrence that some individuals in the germ line have more offspring than others. When individuals leave or join the population, allele frequencies can change as a result of gene flow. Mutations to an individual's DNA may introduce new variation into a population. Allele frequencies can also be altered when individuals do not randomly mate with others in the group. Q: What works by selecting for alleles that confer beneficial traits or behaviors, while selecting against those for deleterious qualities? A:
****
A: natural selection

Answer the following question given this paragraph: Cell division Mitosis M Cell growth stops at this stage. Mitosis divides the nucleus into two nuclei, followed by cytokinesis which divides the cytoplasm. Two genetically identical daughter cells result. Q: What is divided during cytokinesis? A:
OPTIONS:
- chromosomes
- nucleus
- cytoskeleton
- cytoplasm

Answer:
cytoplasm
