Ques: Answer the following question given this paragraph: Bundles of vascular tissue run through the ground tissue of a stem and transport fluids. Plants may vary in how these bundles are arranged. Q: What population on earth is already harming the environment due to less resources to go around? Choices: - whales - rats - insects - humans A:
Ans: humans

Ques: Answer the following question given this paragraph: In 1905, the physicist Albert Einstein developed a new theory about electromagnetic radiation. The theory is often called the wave-particle theory . It explains how electromagnetic radiation can behave as both a wave and a particle. Einstein argued that when an electron returns to a lower energy level and gives off electromagnetic energy, the energy is released as a discrete "packet" of energy. We now call such a packet of energy a photon . According to Einstein, a photon resembles a particle but moves like a wave. You can see this in the Figure below . The theory posits that waves of photons traveling through space or matter make up electromagnetic radiation. Q: Einstein developed a theory about how electromagnetic radiation can behave as both a wave and what else? Choices: - energy - bacteria - sound - particle A:
Ans: particle

Ques: Answer the following question given this paragraph: As Melvin Calvin discovered, carbon fixation is the first step of a cycle. Like an electron transport chain, the Calvin Cycle, shown in Figure below , transfers energy in small, controlled steps. Each step pushes molecules uphill in terms of energy content. Recall that in the electron transfer chain, excited electrons lose energy to NADPH and ATP. In the Calvin Cycle, NADPH and ATP formed in the light reactions lose their stored chemical energy to build glucose. Q: Carbon fixation is the first step of what cycle involving light reactions? Choices: - sun cycle - life cycle - water cycle - calvin cycle A:
Ans: calvin cycle

Ques: Answer the following question given this paragraph: Rheumatic fever is caused by a virus that has antigens similar to molecules in human heart tissues. When the immune system attacks the virus, it may also attack the heart. What type of immune system disease is rheumatic fever? Explain your answer. Q: Name the fever that is caused by a virus that has antigens similar to molecules in human heart tissues. Choices: - Dengue fever - yellow fever - chronic fever - rheumatic fever A:
Ans:
rheumatic fever
