Answer the following question given this paragraph: Bases are ionic compounds that produce negative hydroxide ions (OH - ) when dissolved in water. An ionic compound contains positive metal ions and negative nonmetal ions held together by ionic bonds. (Ions are atoms that have become charged particles because they have either lost or gained electrons. ) An example of a base is sodium hydroxide (NaOH). When it dissolves in water, it produces negative hydroxide ions and positive sodium ions (Na + ). This can be represented by the equation:. Q: What are the ionic compounds that produce negative hydroxide ions when dissolved in water? Choices: - isotopes - acids - enzymes - bases A:
bases
Answer the following question given this paragraph: Near the time of birth, the amniotic sac breaks in a gush of fluid. Often when this occurs, women say that their "water broke. " Labor usually begins within a day of this event. Labor involves contractions of the muscular walls of the uterus, which cause the cervix to dilate. With the mother's help, the contractions eventually push the fetus out of the uterus and through the vagina. Within seconds of birth, the umbilical cord is cut. Without this connection to the placenta, the baby cannot exchange gases, so carbon dioxide quickly builds up in the baby's blood. This stimulates the brain to trigger breathing, and the newborn takes its first breath. See Labor and Birth - BabyCenter Video at http://www. youtube. com/watch?v=BgZ5z6RB06c for additional information. Q: What connection is required for a newborn baby to begin breathing? Choices: - connection to a heat source - connection to a ventilator - connection to the father - connection to the placenta A:
