Answer the following question given this paragraph: You could argue that oxygen is one of the most important, if not THE most important molecule necessary for life. However, oxygen is essentially just a waste product of the light reactions of photosynthesis. It is a "leftover" from a necessary part of the process. All the oxygen that is necessary to maintain most forms of life just happens to be released from the plant during this process. Q: Oxygen is essentially just a waste product of the light reactions of what? Choices: - Fibrinolysis - electrolysis - glycolysis - photosynthesis A:
photosynthesis
Answer the following question given this paragraph: Structures like the human tail bone and whale pelvis are called vestigial structures . Evolution has reduced their size because the structures are no longer used. The human appendix is another example of a vestigial structure. It is a tiny remnant of a once-larger organ. In a distant ancestor, it was needed to digest food. It serves no purpose in humans today. Why do you think structures that are no longer used shrink in size? Why might a full-sized, unused structure reduce an organism's fitness?. Q: Structures like the human tail bone and whale pelvis are called what? Choices: - primordial structures - parasitic structures - adaptations - vestigial structures A:
vestigial structures
Q: Answer the following question given this paragraph: Insight learning , which is based on past experience and reasoning, is a hallmark of the human animal. Humans have used insight learning to solve problems ranging from starting a fire to traveling to the moon. It usually involves coming up with new ways to solve problems. Insight learning generally happens quickly. An animal has a sudden flash of insight. Insight learning requires relatively great intelligence. Human beings use insight learning more than any other species. They have used their intelligence to solve problems ranging from inventing the wheel to flying rockets into space. Q: What type of learning is based on past experience and reasoning? Choices: - experiment - theory - reflect - insight A:
A: insight
