Problem:OPTIONS:
- magnetic
- positively charged protons
- neutrally charged
- electrically charged

Answer the following question given this paragraph: Q: The term ion applies to entire molecules that are? A:
****
A: electrically charged

Answer the following question given this paragraph: Neutrons have approximately the same mass as protons but no charge. They are electrically neutral. The mass of a proton or a neutron is about 1836 times greater than the mass of an electron. Protons and neutrons constitute by far the bulk of the mass of atoms. The discovery of the electron and the proton was crucial to the development of the modern model of the atom and provides an excellent case study in the application of the scientific method. In fact, the elucidation of the atom's structure is one of the greatest detective stories in the history of science. Q: What have approximately the same mass as protons but no charge? A:
OPTIONS:
- atoms
- reactions
- electrons
- neutrons
neutrons

Answer the following question given this paragraph: Wind-blown pollen might land anywhere and be wasted. Another adaptation solved this problem. Plants evolved traits that attract specific animal pollinators. Like the bee in Figure below , a pollinator picks up pollen on its body and carries it directly to another plant of the same species. This greatly increases the chance that fertilization will occur. Q: What does a pollinator pick up from its body and carry directly to another plant of the same species? A:
OPTIONS:
- spore
- pathogen
- seed
- pollen

Answer: pollen

Question: Answer the following question given this paragraph: Earth is warmed by energy that radiates from the sun. Earth radiates some of the energy back into space. Greenhouse gases (GHGs) trap much of the re-radiated energy, causing an increase in the temperature of the atmosphere close to the surface. Q: What is the major source of warmth for earth? A:
OPTIONS:
- the Moon
- seasons
- equator
- the sun
Answer: the sun

input with options: Answer the following question given this paragraph: A single-replacement reaction is one in which an element replaces another element in a compound. An element is in either the solid, liquid, or gas state and is not an ion. The example below shows the reaction of solid magnesium metal with aqueous silver nitrate to form aqueous magnesium nitrate and silver metal. Q: In this type of reaction, an element replaces another element in a compound, and the element is in any state of matter but is not an ion? A:
OPTIONS:
- double-replacement reaction
- replication reaction
- polar reaction
- single-replacement reaction
output: single-replacement reaction

Problem: OPTIONS:
- constructs pressure gradient
- limited pressure gradient
- magnesium pressure gradient
- hydrostatic pressure gradient
Q: Answer the following question given this paragraph: Another mechanism besides diffusion to passively transport materials between compartments is filtration. Unlike diffusion of a substance from where it is more concentrated to less concentrated, filtration uses a hydrostatic pressure gradient that pushes the fluidand the solutes within itfrom a higher pressure area to a lower pressure area. Filtration is an extremely important process in the body. For example, the circulatory system uses filtration to move plasma and substances across the. Q: What is used during filtration to push fluids and solutes, from higher pressure areas to lower pressure areas? A:
Answer:
hydrostatic pressure gradient
