Answer the following question given this paragraph: When two or more waves meet, they interact with each other. The interaction of waves with other waves is called wave interference . Wave interference may occur when two waves that are traveling in opposite directions meet. The two waves pass through each other, and this affects their amplitude. Amplitude is the maximum distance the particles of the medium move from their resting positions when a wave passes through. How amplitude is affected by wave interference depends on the type of interference. Interference can be constructive or destructive. Q: What is the interaction of waves with other waves called? A:
OPTIONS:
- wave mixing
- wave induction
- wave dancing
- wave interference
wave interference

Answer the following question given this paragraph: Figure 35.7 Glial cells support neurons and maintain their environment. Glial cells of the (a) central nervous system include oligodendrocytes, astrocytes, ependymal cells, and microglial cells. Oligodendrocytes form the myelin sheath around axons. Astrocytes provide nutrients to neurons, maintain their extracellular environment, and provide structural support. Microglia scavenge pathogens and dead cells. Ependymal cells produce cerebrospinal fluid that cushions the neurons. Glial cells of the (b) peripheral nervous system include Schwann cells, which form the myelin sheath, and satellite cells, which provide nutrients and structural support to neurons. Q: What is a type of cell that supports neurons and maintains their environment? A:
OPTIONS:
- axon cell
- neurofilament cell
- interneuron cell
- glial cell

Answer: glial cell

- tails
- pores
- scales
- gills
Answer: gills

OPTIONS:
- microbes
- fungi
- spores
- angiosperms
output: angiosperms

Problem: OPTIONS:
- natural process
- natural change
- natural resources
- natural selection
Q: Answer the following question given this paragraph: A community is the biotic component of an ecosystem. It consists of the populations of all the species that live in the same area. Populations in communities often interact with each other. Community interactions are important factors in natural selection. They help shape the evolution of the interacting species. Types of community interactions include predation, competition, and symbiosis. You'll read about each type of interaction in this lesson. Q: Community interactions are important factors in what? A:
Answer:
natural selection
