Answer the following question given this paragraph: Unfortunately, using energy from nuclear fusion is far from a reality. Scientists are a long way from developing the necessary technology. One problem is raising temperatures high enough for fusion to take place. Another problem is that matter this hot exists only in the plasma state. There are no known materials that can contain plasma, although a magnet might be able to do it. That's because plasma consists of ions and responds to magnetism. You can learn more about research on nuclear fusion at the URL below. Q: In which state does matter need to be for nuclear fusion? A:

OPTIONS:
- cells state
- solid state
- gaseous state
- plasma state

Answer: plasma state

Answer the following question given this paragraph: Macrophages are large WBCs that can also swallow and destroy old and dying cells, bacteria, or viruses. Below, a macrophage is attacking and swallowing two particles, possibly disease-causing pathogens ( Figure below ). Macrophages also release chemical messages that cause the number of WBCs to increase. Q: Macrophages, which can swallow and destroy old and dying cells, bacteria, or viruses, are large types of what cells? A:

OPTIONS:
- red blood cells
- white brain cells
- dendritic cells
- white blood cells

Answer: white blood cells
