Question: Answer the following question given this paragraph: 47.2 The Importance of Biodiversity to Human Life Humans use many compounds that were first discovered or derived from living organisms as medicines: secondary plant compounds, animal toxins, and antibiotics produced by bacteria and fungi. More medicines are expected to be discovered in nature. Loss of biodiversity will impact the number of pharmaceuticals available to humans. Crop diversity is a requirement for food security, and it is being lost. The loss of wild relatives to crops also threatens breeders' abilities to create new varieties. Ecosystems provide ecosystem services that support human agriculture: pollination, nutrient cycling, pest control, and soil development and maintenance. Loss of biodiversity threatens these ecosystem services and risks making food production more expensive or impossible. Wild food sources are mainly aquatic, but few are being managed for sustainability. Fisheries' ability to provide protein to human populations is threatened when extinction occurs. Biodiversity may provide important psychological benefits to humans. Additionally, there are moral arguments for the maintenance of biodiversity. Q: Humans use many compounds that were first discovered or derived from living organisms as medicines: secondary plant compounds, animal toxins, and antibiotics produced by these? A:
OPTIONS:
- bacteria and tumors
- molecules and fungi
- tumors and fungi
- bacteria and fungi
Answer: bacteria and fungi

input with options: Answer the following question given this paragraph: A suspension is a heterogeneous mixture in which some of the particles settle out of the mixture upon standing. The particles in a suspension are far larger than those of a solution and thus gravity is able to pull them down out of the dispersion medium (water). The typical diameter for the dispersed particles (the sand) of a suspension is about 1000 times greater than those of a solution (less than approximately two nanometers for particles in solution, compared to greater than 1000 nanometers for particles in suspension). Unlike in a solution, the dispersed particles can be separated from the dispersion medium by filtering. Suspensions are heterogeneous because at least two different substances in the mixture can be identified. Q: What do you call a mixture in which some particles settle out of it when it is left standing? A:
OPTIONS:
- emulsion
- alloy
- homogenous
- suspension
output: suspension

Q: Answer the following question given this paragraph: Q: The arid environment of a desert, for instance, can quickly deplete an animal of what? A:

OPTIONS:
- strength
- protein
- air
- water

A: water

input: OPTIONS:
- one
- five
- two
- three Now, answer this question: Answer the following question given this paragraph: Galaxies are divided into three types, according to shape. There are spiral galaxies, elliptical galaxies, and irregular galaxies. Spiral galaxies are a rotating disk of stars and dust. In the center is a dense bulge of material. Several arms spiral out from the center. Spiral galaxies have lots of gas and dust and many young stars. Figure below shows a spiral galaxy from the side. You can see the disk and central bulge. Q: How many types of galaxies are there? A:
A:
output: three

Answer the following question given this paragraph: Chromosomal alterations are mutations that change chromosome structure. Q: Alterations that change chromosome structure are known as? A:

OPTIONS:
- lesions
- traits
- deformities
- mutations

Answer: mutations

Q: Answer the following question given this paragraph: Sedimentary rocks form when sediments are compacted and cemented together. Sediments are pieces of rock. They may be gravel, sand, silt, or clay. Some sedimentary rocks form the solid minerals left behind after a liquid evaporates. Q: What type of rocks form when sediments are compacted and cemented together? A:

OPTIONS:
- metamorphic rocks
- crystalline rocks
- igneous rocks
- sedimentary rocks

A:
sedimentary rocks
