Answer the following question given this paragraph: Electric charge is a physical property of particles or objects that causes them to attract or repel each other without touching. All electric charge is based on the protons and electrons in atoms. A proton has a positive electric charge, and an electron has a negative electric charge (see Figure below ). Q: What kind of charge does a proton have? Choices: - ionic - constant - negative - positive A:
positive
Answer the following question given this paragraph: 4. Zeros that appear after all nonzero digits are called right-end zeros. Right-end zeros in a number that lacks a decimal point are not significant. A. 140 has two significant figures. Q: What do we call zeros that appear after nonzero digits? Choices: - left-end zeros - significant digits - placeholders - right-end zeros A:
right-end zeros
Q: 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:
A: connection to the placenta
Question: Answer the following question given this paragraph: Figure 11.13 Muscles of the Anterior Neck The anterior muscles of the neck facilitate swallowing and speech. The suprahyoid muscles originate from above the hyoid bone in the chin region. The infrahyoid muscles originate below the hyoid bone in the lower neck. Q: The anterior muscles of the neck facilitate swallowing and what else? Choices: - hearing - crying - perspiration - speech A:
Answer: speech

Answer the following question given this paragraph: The lifecycle of basidiomycetes includes alternation of generations (Figure 24.16). Spores are generally produced through sexual reproduction, rather than asexual reproduction. The club-shaped basidium carries spores called basidiospores. In the basidium, nuclei of two different mating strains fuse (karyogamy), giving rise to a diploid zygote that then undergoes meiosis. The haploid nuclei migrate into basidiospores, which germinate and generate monokaryotic hyphae. The mycelium that results is called a primary mycelium. Mycelia of different mating strains can combine and produce a secondary mycelium that contains haploid nuclei of two different mating strains. This is the dikaryotic stage of the basidiomyces lifecyle and and it is the dominant stage. Eventually, the secondary mycelium generates a basidiocarp, which is a fruiting body that protrudes from the groundthis is what we think of as a mushroom. The basidiocarp bears the developing basidia on the gills under its cap. Q: Spores are generally produced through what type of reproduction? Choices: - similar - asexual - hormone - sexual A:
**Answer**
sexual

Answer the following question given this paragraph: Like hurricanes, winter storms develop from cyclones. But in the case of winter storms, the cyclones form at higher latitudes. In North America, cyclones often form when the jet stream dips south in the winter. This lets dry polar air pour south. At the same time, warm moist air from the Gulf of Mexico flows north. When the two air masses meet, the differences in temperature and pressure cause strong winds and heavy precipitation. Two types of winter storms that occur in the U. S. are blizzards and lake-effect snow storms. Q: Winter storms develop from what, which form at high altitudes and are associated with hurricanes as well? Choices: - fronts - currents - droughts - cyclones A:
**Answer**
cyclones
