Answer the following question given this paragraph: Plant-like protists, which are autotrophs that photosynthesize. Q: Plant-like protists are autotrophs capable of what process? Choices: - sexual reproduction - microevolution - regeneration - photosynthesis A:
photosynthesis
Q: Answer the following question given this paragraph: Streams often start in mountains, where the land is very steep. You can see an example in Figure below . A mountain stream flows very quickly because of the steep slope. This causes a lot of erosion and very little deposition. The rapidly falling water digs down into the stream bed and makes it deeper. It carves a narrow, V-shaped channel. Q: Where do streams often start? Choices: - valleys - oceans - plains - mountains A:
A: mountains
Question: Answer the following question given this paragraph: Bacteria are surrounded by a cell wall consisting of peptidoglycan . This complex molecule consists of sugars and amino acids. The cell wall is important for protecting bacteria. The cell wall is so important that some antibiotics, such as penicillin, kill bacteria by preventing the cell wall from forming. Q: What are surrounded by a cell wall consisting of peptidoglycan? Choices: - viruses - protozoa - amoeba - bacteria A:
Answer: bacteria
