Answer the following question given this paragraph: During anaphase I the spindle fibers shorten, and the homologous chromosome pairs are separated from each other. This occurs as the chiasmata are severed, pulling homologous chromosomes apart. One chromosome from each pair moves toward one pole, with the other moving toward the other pole, resulting in a cell with 23 chromosomes at one pole and the other 23 at the other pole. Each chromosome still contains a pair of sister chromatids; the sister chromatids remain attached at the centromere. Q: How many pairs of chromosomes are there? Choices: - 16 - 25 - 24 - 23 A:
23
Q: Answer the following question given this paragraph: Solution 1. Saltwater acts as if it were a single substance even though it contains two substancessalt and water. Saltwater is a homogeneous mixture, or a solution. Soil is composed of small pieces of a variety of materials, so it is a heterogeneous mixture. Water is a substance; more specifically, because water is composed of hydrogen and oxygen, it is a compound. Oxygen, a substance, is an element. Q: Saltwater is a homogeneous mixture, another term for what? Choices: - structure - element - lipid - solution A:
A: solution
Question: Answer the following question given this paragraph: Sexual reproduction results in offspring that are genetically unique. They differ from both parents and also from each other. This occurs for a number of reasons. Q: What type of reproduction results in genetically unique offspring? Choices: - mitosis - asexual reproduction - internal reproduction - sexual reproduction A:
Answer: sexual reproduction

Answer the following question given this paragraph: 20.3 | Terrestrial Biomes By the end of this section, you will be able to: Identify the two major abiotic factors that determine the type of terrestrial biome in an area Recognize distinguishing characteristics of each of the eight major terrestrial biomes Earth's biomes can be either terrestrial or aquatic. Terrestrial biomes are based on land, while aquatic biomes include both ocean and freshwater biomes. The eight major terrestrial biomes on Earth are each distinguished by characteristic temperatures and amount of precipitation. Annual totals and fluctuations of precipitation affect the kinds of vegetation and animal life that can exist in broad geographical regions. Temperature variation on a daily and seasonal basis is also important for predicting the geographic distribution of a biome. Since a biome is defined by climate, the same biome can occur in geographically distinct areas with similar climates (Figure 20.18). There are also large areas on Antarctica, Greenland, and in mountain ranges that are covered by permanent glaciers and support very little life. Strictly speaking, these are not considered biomes and in addition to extremes of cold, they are also often deserts with very low precipitation. Q: Terrestrial and aquatic are the two basic categories of what, on earth? Choices: - substrates - atmospheres - dendrites - biomes A:
**Answer**
biomes
