Question: Answer the following question given this paragraph: Reproduction Fungi reproduce sexually and/or asexually. Perfect fungi reproduce both sexually and asexually, while the so-called imperfect fungi reproduce only asexually (by mitosis). In both sexual and asexual reproduction, fungi produce spores that disperse from the parent organism by either floating on the wind or hitching a ride on an animal. Fungal spores are smaller and lighter than plant seeds. The giant puffball mushroom bursts open and releases trillions of spores. The huge number of spores released increases the likelihood of landing in an environment that will support growth (Figure 24.6). Q: What do all respiratory diseases affect? Choices: - liquid exchange process - helium exchange process - transit exchange process - gas exchange process A:
Answer: gas exchange process

Question: Answer the following question given this paragraph: Molecules move from an area of high concentration to an area of lower concentration until an equilibrium is met. The molecules continue to cross the membrane at equilibrium, but at equal rates in both directions. Q: What protects reptiles from injury and loss of water? Choices: - hairs - pores - tail - scales A:
Answer: scales

Question: Answer the following question given this paragraph: 28.2 Simultaneity And Time Dilation Two events are defined to be simultaneous if an observer measures them as occurring at the same time. They are not necessarily simultaneous to all observerssimultaneity is not absolute. Time dilation is the phenomenon of time passing slower for an observer who is moving relative to another observer. Observers moving at a relative velocity v do not measure the same elapsed time for an event. Proper time t 0 is the time measured by an observer at rest relative to the event being observed. Proper time is related to the time by an Earth-bound observer by the equation. Q: Two events are defined to be simultaneous if an observer measures them as occurring at what? Choices: - midnight - opposite times - different times - same time A:
Answer:
same time
