Answer the following question given this paragraph: Plants alternate between haploid and diploid generations. Haploid cells have one of each pair of chromosomes. Diploid cells have two of each pair. Q: Plants alternate between haploid and what? Choices: - triploid - monoplooid - monoxoid - diploid A:
diploid
Answer the following question given this paragraph: Yes! The outer core, anyway. The outer core is liquid metal, like in this photo. Of course, the metal is under an incredible amount of pressure. Q: What is the outer core made of? Choices: - compressed air - solid rock - solid iron - liquid metal A:
liquid metal
Q: Answer the following question given this paragraph: Fatty Acids. Saturated fatty acids have straight chains, like the three fatty acids shown on the left. Unsaturated fatty acids have bent chains, like all the other fatty acids in the figure. Q: What type of fatty acids have bent chains? Choices: - cholesterol - saturated fatty acids - lipids - unsaturated fatty acids A:
A: unsaturated fatty acids
Question: Answer the following question given this paragraph: Within a nebula, there are varying regions where gravity has caused the gas and dust to clump together. The gravitational attraction of these clumps pull more atoms into the clump. As this accretion continues, the gas pressure increases and the core of the protostar gets hotter and hotter. If the protostar gets dense enough and hot enough, a fusion reaction will ignite and the star lights up. The minimum mass for the formation of a star is about 80 times the mass of Jupiter. A star is a very large, very hot ball of gas which has hydrogen fusing into helium in the core. Stars spend the majority of their life fusing hydrogen into helium. When the hydrogen is nearly used up, the star can fuse helium into heavier elements. Throughout this process, a battle goes on in the core of the star between gravity trying to collapse the star and temperature-produced gas pressure pushing the material in the star outward. During the life of a star, there is a balance between the gas pressure pushing out and gravity pushing in. Q: When the hydrogen is nearly used up, the star can fuse which element into heavier elements? Choices: - carbon - xenon - oxygen - helium A:
Answer: helium
