Answer the following question given this paragraph: The atomic number of an element is the number of protons in the nucleus of each atom of that element. An atom can be classified as a particular element based solely on its atomic number. For example, any atom with an atomic number of 8 (its nucleus contains 8 protons) is an oxygen atom, and any atom with a different number of protons would be a different element. The periodic table ( Figure below ) displays all of the known elements and is arranged in order of increasing atomic number. In this table, an element's atomic number is indicated above the elemental symbol. Hydrogen, at the upper left of the table, has an atomic number of 1. Every hydrogen atom has one proton in its nucleus. Next on the table is helium, whose atoms have two protons in the nucleus. Lithium atoms have three protons, beryllium atoms have four, and so on. Since atoms are neutral, the number of electrons in an atom is equal to the number of protons. Therefore, hydrogen atoms all have one electron occupying the space outside of the nucleus. Q: An atom can be classified as a particular element based solely on its what? A:

OPTIONS:
- light number
- spectrum
- ability
- atomic number

Answer: atomic number

Problem: OPTIONS:
- alter directions
- opposite direction
- same direction
- random directions
Q: Answer the following question given this paragraph: We discussed earlier some basic principles about the behavior of gases called the kinetic-molecular theory. Among other things, this theory suggests that gas molecules are in constant motion, and the average speed of the individual gas particles is dependent upon temperature the higher the temperature, the faster the molecules move. It is not just gas particles that are in constant motion. The molecules and ions that make up liquids and solutions are also continually moving in nearly random directions. As a result, molecules and ions in a solution will collide with one another fairly frequently. As with gases, a temperature increase will produce an increase in the average particle speed. Q: As per the kinetic-molecular theory, in what direction do the molecules and ions of liquids move? A:
Answer: random directions

Problem:OPTIONS:
- hemoglobin
- white blood cells
- erythrocytes
- platelets

Answer the following question given this paragraph: Platelets ( Figure below ) are very small, but they are very important in blood clotting. Platelets are not cells. They are sticky little pieces of larger cells. Platelets bud off large cells that stay in the bone marrow. When a blood vessel gets cut, platelets stick to the injured areas. They release chemicals called clotting factors, which cause proteins to form over the wound. This web of proteins catches red blood cells and forms a clot. This clot stops more blood from leaving the body through the cut blood vessel. The clot also stops bacteria from entering the body. Platelets survive in the blood for ten days before they are removed by the liver and spleen. Q: What part of blood releases clotting factors? A:
****
A: platelets

Answer the following question given this paragraph: It could easily be said that a cell is the fundamental unit of life, the smallest unit capable of life or the structural and functional unit necessary for life. But whatever it is, a cell is necessary for life. And as shown above, a cell may be filled with all sorts of structures, each with its own specific function. This concept will discuss some of the fundamental properties of the cell, with lessons that include the cell structure, transport in and out of the cell, energy metabolism, and cell division and reproduction. Q: What is the smallest unit capable of life known as? A:
OPTIONS:
- living thing
- organism
- insect
- a cell
a cell

Answer the following question given this paragraph: Evolution occurs in a population when allele frequencies change over time. What causes allele frequencies to change? That question was answered by Godfrey Hardy and Wilhelm Weinberg in 1908 (see the Hardy-Weinberg Theorem concept). Q: In what year was the hardy-weinberg theorem formulated? A:
OPTIONS:
- 1938
- 1901
- 1928
- 1908

Answer: 1908

input with options: Answer the following question given this paragraph: A transverse wave can be characterized by the high and low points reached by particles of the medium as the wave passes through. This is illustrated in Figure below . The high points are called crests, and the low points are called troughs. Q: What are the high points of a transverse wave called? A:
OPTIONS:
- peaks
- troughs
- ridges
- crests
output:
crests
