Answer the following question given this paragraph: Independent assortment occurs when chromosomes go to opposite poles of the cell in anaphase I. Which chromosomes end up together at each pole is a matter of chance. You can see this in Figures 5.15 and 5.16 as well. Q: Independent assortment occurs when what go to opposite poles of the cell in anaphase i? Choices: - receptors - ballasts - prokaryotes - chromosomes A:
chromosomes
Answer the following question given this paragraph: Bacteria lack many of the structures that eukaryotic cells contain. For example, they don't have a nucleus. They also lack membrane-bound organelles, such as mitochondria or chloroplasts. The DNA of a bacterial cell is also different from a eukaryotic cell. Bacterial DNA is contained in one circular chromosome, located in the cytoplasm. Eukaryotes have several linear chromosomes. Bacteria also have two additional unique features: a cell wall and flagella. Q: Bacterial dna is contained in one circular chromosome, located where? Choices: - neuron - mucus - cerebellum - cytoplasm A:
cytoplasm
Q: Answer the following question given this paragraph: Steroid hormones are made of lipids, such as phospholipids and cholesterol. They are fat soluble, so they can diffuse across the plasma membrane of target cells and bind with receptors in the cytoplasm of the cell (see Figure below ). The steroid hormone and receptor form a complex that moves into the nucleus and influences the expression of genes, essentially acting as a transcription factor. Examples of steroid hormones include cortisol and sex hormones. Q: What are steroid hormones made of? Choices: - water - amino acid - organisms - lipids A:
A: lipids
Question: Answer the following question given this paragraph: The most common two-lens telescope, like the simple microscope, uses two convex lenses and is shown in Figure 26.23(b). The object is so far away from the telescope that it is essentially at infinity compared with the focal lengths of the lenses ( d o ). The first image is thus produced at. Q: The most common two-lens telescope, like the simple microscope, uses lenses of what shape? Choices: - concave - angular - cylindrical - convex A:
Answer: convex

Answer the following question given this paragraph: All the cells of your body need oxygen, which they get from red blood cells. Red blood cells, in turn, get oxygen in the lungs. The lungs are the main organs of the respiratory system. The respiratory system is the body system that exchanges gases with the outside air. It brings air containing oxygen into the body for the cells. It also releases carbon dioxide from the cells into the air. Q: Where do the cells in your body get oxygen from? Choices: - white blood cells - the digestive system - pores - red blood cells A:
(A).
red blood cells
