Answer the following question given this paragraph: During the Permian Period, all the major landmasses moved together to form one supercontinent. The supercontinent has been named Pangaea. You can see how it looked in Figure below . At this time, temperatures were extreme and the climate became very dry. As a result, plants and animals evolved ways to cope with dryness. For example, reptiles evolved leathery skin. This helped prevent water loss. Plants evolved waxy leaves for the same purpose. Q: All the major landmasses moved together to form one supercontinent in which period? A:
****
A: permian

Answer the following question given this paragraph: Q: Where does oxygen enter the blood? A:
OPTIONS:
- in the heart
- in the veins
- in the liver
- in the lungs
in the lungs

Answer the following question given this paragraph: Saturated hydrocarbons contain only single bonds between carbon atoms. They are also called alkanes. They may form straight-chain, branched-chain, or cyclic molecules. Compounds with the same number of atoms but different shapes are called isomers. Q: What is another word for saturated hydrocarbons? A:
OPTIONS:
- catalysts
- enzymes
- aldehydes
- alkanes

Answer: alkanes

Question: Answer the following question given this paragraph: Convection in the mantle drives the movement of the plates of lithosphere over the Earth's surface. New oceanic crust forms at the ridge and pushes the older seafloor away from the ridge horizontally. Q: Convection in which part of the earth drives the movement of the plates of lithosphere over the earth's surface? A:
OPTIONS:
- atmosphere
- ocean
- upper crust
- mantle
Answer: mantle

input with options: Answer the following question given this paragraph: This equation is based on the conservation of energy and conservation of charge. Electrical potential energy can be described by the equation PE = qV , where q is the electric charge and V is the voltage. Thus the energy supplied by the source is qV , while that dissipated by the resistors is. Q: Electrical potential energy can be described by the equation pe = qv, where q is the electric charge and v is what? A:
OPTIONS:
- amplitude
- wavelength density
- frequency
- voltage
output: voltage

Problem: OPTIONS:
- catalysts
- oxides
- isotopes
- cations
Q: Answer the following question given this paragraph: Some elements lose one or more electrons in forming ions. These ions are known as " cations " because they are positively charged and migrate toward the negative electrode ( cathode ) in an electrical field. Looking at the periodic table below, we know that the group 1 elements are all characterized by having one s electron in the outer orbit and group 2 elements have two s electrons in the outer orbit. These electrons are loosely attached to the atom and can easily be removed, leaving more protons in the atom that there are electrons, so the resulting ion has a positive charge. Cations can also be formed from electron loss to many of the transition elements. Q: What are electrons lost during the formation of ions called? A:
Answer:
cations
