Autosomes are chromosomes that contain genes for characteristics that are unrelated to sex. These chromosomes are the same in males and females. The great majority of human genes are located on autosomes. At the link below, you can click on any human chromosome to see which traits its genes control. http://www. ornl. gov/sci/techresources/Human_Genome/posters/chromosome/chooser. shtml. Q: Which blood vessels is oxygen transferred through? Choices: - cilia - arteries - veins - capillaries A:

Answer the following question given this paragraph: The properties of cyclic hydrocarbons are generally quite similar to those of the corresponding open-chain compounds. So cycloalkanes (with the exception of cyclopropane, which has a highly strained ring) act very much like noncyclic alkanes. Cyclic structures containing five or six carbon atoms, such as cyclopentane and cyclohexane, are particularly stable. We will see in Chapter 16 "Carbohydrates" that some carbohydrates (sugars) form five- or six-membered rings in solution. Q: The properties of cyclic hydrocarbons are generally quite similar to those of the corresponding open-chain compounds. so cycloalkanes (with the exception of cyclopropane, which has a highly strained ring) act very much like noncyclic alkanes. cyclic structures containing five or six carbon atoms, such as cyclopentane and cyclohexane, are particularly what? Choices: - large - reactive - small - stable A:
