Answer the following question given this paragraph: Static electricity is a buildup of electric charges on objects. It occurs when electrons are transferred from one object to another. Q: What is the term for the buildup of electric charge on an object, which can be transferred to another when touched? Choices: - electromagnetic electricity - electric potential - static cling - static electricity A:
static electricity
Answer the following question given this paragraph: Plants are somewhat limited by temperature in terms of where they can grow. They need temperatures above freezing while they are actively growing. They also need light, carbon dioxide, and water. These substances are required for photosynthesis. Like most other living things, plants need oxygen. Oxygen is required for cellular respiration. In addition, plants need minerals. The minerals are required to make proteins and other organic molecules. Q: Photosynthesis requires light, water and what else? Choices: - seasons - nitrogen - soil - carbon dioxide A:
carbon dioxide
Q: Answer the following question given this paragraph: 28.2 Simultaneity And Time Dilation Two events are defined to be simultaneous if an observer measures them as occurring at the same time. They are not necessarily simultaneous to all observerssimultaneity is not absolute. Time dilation is the phenomenon of time passing slower for an observer who is moving relative to another observer. Observers moving at a relative velocity v do not measure the same elapsed time for an event. Proper time t 0 is the time measured by an observer at rest relative to the event being observed. Proper time is related to the time by an Earth-bound observer by the equation. Q: Two events are defined to be simultaneous if an observer measures them as occurring at what? Choices: - midnight - opposite times - different times - same time A:
A: same time
Question: Answer the following question given this paragraph: At equilibrium, the forward and reverse reactions proceed at equal rates. The driving force in each direction is equal, because the free energy of the reactants and products under equilibrium conditions is equivalent (G = 0). We also know that, at equilibrium, Q = K eq . For a reaction that has reached equilibrium, the equation above becomes the following:. Q: What state is achieved when the forward and reverse reactions proceed at equal rates? Choices: - neutrality - equality - constant - equilibrium A:
Answer: equilibrium

Answer the following question given this paragraph: You are already very familiar with Earth's gravity. It constantly pulls you toward the center of the planet. It prevents you and everything else on Earth from being flung out into space as the planet spins on its axis. It also pulls objects above the surface, from meteors to skydivers, down to the ground. Gravity between Earth and the moon and between Earth and artificial satellites keeps all these objects circling around Earth. Gravity also keeps Earth moving around the sun. Q: What force pulls people and objects toward the center of the earth? Choices: - magnetism - variation - motion - gravity A:
**Answer**
gravity

Answer the following question given this paragraph: Dizygotic twins (fraternal or non-identical) share only about half of their polymorphisms. These twins are helpful to study as they tend to share many aspects of their environment. As they are born in the same place, usually within a few minutes of each other, they share many environmental conditions. They had the same in utero environment, they usually have a similar or the same parenting style during their childhood, and a similar or the same education. Similarities during childhood usually occur with wealth, culture, and their community. Q: What are two other terms for dizygotic twins, which make good study subjects because they share many environmental conditions, but only about half of their polymorphisms? Choices: - fractional - identical twins - interdependant twins - fraternal, non-identical A:
**Answer**
fraternal, non-identical
