Q: Answer the following question given this paragraph: Inside the atom, two types of subatomic particles have electric charge: electrons, which have an electric charge of -1, and protons, which have an opposite but equal electric charge of +1. The model of an atom in the Figure below shows both types of charged particles. Protons are found inside the nucleus at the center of the atom, and they give the nucleus a positive charge. (There are also neutrons in the nucleus, but they have no electric charge. ) Negative electrons stay in the area surrounding the positive nucleus because of the electromagnetic force of attraction between them. Q: What kind of charges do protons give the nucleus? A:

OPTIONS:
- negative
- dynamic
- neutral
- positive

A: positive

input: OPTIONS:
- multiply protons and neutrons
- subtract protons from electrons
- divide protons and neutrons
- add up protons and neutrons Now, answer this question: Answer the following question given this paragraph: The atomic weight of an element is a weighted average of its isotopes. Q: How do you determine the atomic weight of an element? A:
A:
output: add up protons and neutrons

Answer the following question given this paragraph: The basic unit of matter is an atom . At the center of an atom is its nucleus . Protons are positively charged particles in the nucleus. Also in the nucleus are neutrons with no electrical charge. Orbiting the nucleus are tiny electrons. Electrons are negatively charged. An atom with the same number of protons and electrons is electrically neutral. If the atom has more or less electrons to protons it is called an ion . An ion will have positive charge if it has more protons than electrons. It will have negative charge if it has more electrons than protons. Q: What is the basic unit of matter? A:

OPTIONS:
- neutrons
- calories
- ions
- atoms

Answer: atoms

Problem: OPTIONS:
- mono zones
- extinction zones
- gap zones
- hybrid zones
Q: Answer the following question given this paragraph: 18.3 Reconnection and Rates of Speciation Speciation is not a precise division: overlap between closely related species can occur in areas called hybrid zones. Organisms reproduce with other similar organisms. The fitness of these hybrid offspring can affect the evolutionary path of the two species. Scientists propose two models for the rate of speciation: one model illustrates how a species can change slowly over time; the other model demonstrates how change can occur quickly from a parent generation to a new species. Both models continue to follow the patterns of natural selection. Q: What is the name for areas where there is overlap between closely related species? A:
Answer: hybrid zones

Answer the following question given this paragraph: Chemical reactions in the real world don't always go exactly as planned on paper. In the course of an experiment, many things will contribute to the formation of less product than would be predicted. Besides spills and other experimental errors, there are usually losses due to an incomplete reaction, undesirable side reactions, etc. Chemists need a measurement that indicates how successful a reaction has been. This measurement is called the percent yield. Q: What is the term for proportion of amount of product actually produced in a chemical reaction versus predicted amount ? A:

OPTIONS:
- calculus yield
- decrease yield
- percent impact
- percent yield

Answer:
percent yield
