input: OPTIONS:
- flowers
- roots
- proteins wall
- cell wall Now, answer this question: Answer the following question given this paragraph: Figure 31.3 Cellulose, the main structural component of the plant cell wall, makes up over thirty percent of plant matter. It is the most abundant organic compound on earth. Plants are able to make their own cellulose, but need carbon from the soil to do so. Q: Cellulose is the main structural component of what part of the plant cell, and makes up over thirty percent of plant matter? A:
A:
output: cell wall

Answer the following question given this paragraph: Weathering and erosion. Water, wind, ice, and even plants and animals all act to wear down rocks. Over time they can break larger rocks into smaller pieces called sediments. Moving water, wind, and glaciers then carry these pieces from one place to another. The sediments are eventually dropped, or deposited , somewhere. The sediments may then be compacted and cemented together. This forms a sedimentary rock. This whole process can take hundreds or thousands of years. Q: What is the term for the small particles that rocks are worn down to by water and wind? A:

OPTIONS:
- fragments
- pebbles
- organisms
- sediments

Answer: sediments

Problem: OPTIONS:
- lungs
- layers
- pores
- gills
Q: Answer the following question given this paragraph: Fish have gills that allow them to "breathe" oxygen in water. Water enters the mouth, passes over the gills, and exits the body through a special opening. Gills absorb oxygen from the water as it passes over them. Q: What do fish have that allow them to "breathe" oxygen in water? A:
Answer: gills

Problem:OPTIONS:
- lungs
- heart
- liver
- brain

Answer the following question given this paragraph: Cerebral Cortex Compared to other vertebrates, mammals have exceptionally large brains for their body size. An entire alligator's brain, for example, would fill about one and a half teaspoons. This increase in brain to body size ratio is especially pronounced in apes, whales, and dolphins. While this increase in overall brain size doubtlessly played a role in the evolution of complex behaviors unique to mammals, it does not tell the whole story. Scientists have found a relationship between the relatively high surface area of the cortex and the intelligence and complex social behaviors exhibited by some mammals. This increased surface area is due, in part, to increased folding of the cortical sheet (more sulci and gyri). For example, a rat cortex is very smooth with very few sulci and gyri. Cat and sheep cortices have more sulci and gyri. Chimps, humans, and dolphins have even more. Q: What organ do mammals have that is exceptionally large for their body size? A:
****
A: brain

Answer the following question given this paragraph: The single-celled prokaryotic organism otherwise known as bacteria. And all it takes is one to quickly grow, under just the right conditions, into millions and billions. Luckily, we know how to control bacteria when necessary. But bacteria do serve many important purposes. In fact, we could not survive without them. Q: What type of organism is a bacteria? A:
OPTIONS:
- multicellular organism
- fungi
- paramecium
- single-celled prokaryotic
single-celled prokaryotic
