Q: What is the tubular passageway through which the embryo or fetus leaves the mother's body during birth? Read this paragraph and choose the correct option from the provided answers: The vagina is a tubular passageway through which the embryo or fetus leaves the mother's body during birth. The vagina is also where the male deposits sperm during mating. Choices: - cervix - penis - uterus - vagina A:

Q: Free atoms are spherical in shape, so the relative sizes of the elements can be compared by looking at each atom's atomic what? Read this paragraph and choose the correct option from the provided answers: One important characteristic that determines the way in which elements behave is the total size of each atom. Free atoms are spherical in shape, so the relative sizes of the elements can be compared by looking at each atom's atomic radius , which is the distance from an atom's nucleus to the electrons in the outermost orbitals. You might expect atoms to generally grow larger as they go up in atomic number (which is equal to the total number of electrons in the neutral atom). Indeed, if you look at a single group of the periodic table, this trend holds true. Iodine is larger than bromine, which is in turn larger than chlorine and fluorine. In the case of a single group, each successive row places electrons in a higher principal energy level. Since higher energy levels are farther from the nucleus on average, this results in a larger total volume occupied by the atom. Choices: - weight - axis - angles - radius A:
**Answer**
radius

Q: In a food chain, only about 10 percent of what passes to the next level? Read this paragraph and choose the correct option from the provided answers: At each level of a food chain, a lot of energy is lost. Only about 10 percent of the energy passes to the next level. Where does that energy go? Some energy is given off as heat. Some energy goes into animal wastes. Energy also goes into growing things that another consumer can't eat, like fur. It's because so much energy is lost that most food chains have just a few levels. There's not enough energy left for higher levels. Choices: - mineral - vitamins - hydrogen - energy A:
**Answer**
energy
