Answer the following question given this paragraph: Occipital Bone The occipital bone is the single bone that forms the posterior skull and posterior base of the cranial cavity (Figure 7.9; see also Figure 7.8). On its outside surface, at the posterior midline, is a small protrusion called the external occipital protuberance, which serves as an attachment site for a ligament of the posterior neck. Lateral to either side of this bump is a superior nuchal line (nuchal = "nape" or "posterior neck"). The nuchal lines represent the most superior point at which muscles of the neck attach to the skull, with only the scalp covering the skull above these lines. On the base of the skull, the occipital bone contains the large opening of the foramen magnum, which allows for passage of the spinal cord as it exits the skull. On either side of the foramen magnum is an oval-shaped occipital condyle. These condyles form joints with the first cervical vertebra and thus support the skull on top of the vertebral column. Q: What is the single bone that forms the posterior skull and posterior base of the cranial cavity? Choices: - limbic bone - maxilla - radiating bone - occipital bone A:
occipital bone
Answer the following question given this paragraph: Osmosis is the diffusion of water molecules across a semipermeable membrane and down a concentration gradient. They can move into or out of a cell, depending on the concentration of the solute. Q: What is the diffusion of water molecules across a semipermeable membrane? Choices: - organelle motion - electrolysis - active transport - osmosis A:
osmosis

Answer the following question given this paragraph: 44.3 | Terrestrial Biomes By the end of this section, you will be able to: Identify the two major abiotic factors that determine terrestrial biomes Recognize distinguishing characteristics of each of the eight major terrestrial biomes The Earth's biomes are categorized into two major groups: terrestrial and 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. Comparing the annual totals of precipitation and fluctuations in precipitation from one biome to another provides clues as to the importance of abiotic factors in the distribution of biomes. Temperature variation on a daily and seasonal basis is also important for predicting the geographic distribution of the biome and the vegetation type in the biome. The distribution of these biomes shows that the same biome can occur in geographically distinct areas with similar climates (Figure 44.12). Q: The earth's biomes are categorized into two major groups named what? Choices: - icelandic and aquatic - aquatic and galactic - terrestrial and galactic - terrestrial and aquatic A:
**Answer**
terrestrial and aquatic
Q: Answer the following question given this paragraph: The biogeochemical cycle that recycles water is the water cycle. The water cycle involves a series of interconnected pathways involving both the biotic and abiotic components of the biosphere. Water is obviously an extremely important aspect of every ecosystem. Life cannot exist without water. Many organisms contain a large amount of water in their bodies, and many live in water, so the water cycle is essential to life on Earth. Water continuously moves between living organisms, such as plants, and non-living things, such as clouds, rivers, and oceans ( Figure below ). Q: What is the biogeochemical cycle that recycles water called? Choices: - water theory - Liquid Cycle - Water Table - water cycle A:
A: water cycle
