Q: What is the term for the process in which an area that has never before been colonized changes through time? Read this paragraph and choose the correct option from the provided answers: Ecological succession is the process in which a community changes through time. Primary succession occurs in an area that has never before been colonized. Secondary succession occurs in a formerly inhabited area that was disturbed. Choices: - continuous succession - environmental succession - colony succession - ecological succession A:
ecological succession

Q: Deep within the earth what force is so great that a rock behaves like a stretched rubber band? Read this paragraph and choose the correct option from the provided answers: The amount of stress on a rock may be greater than the rock's strength. In that case, the rock will undergo strain or deformation ( Figure below ). Deep within the Earth, the pressure is very great. A rock behaves like a stretched rubber band. When the stress stops, the rock goes back to its original shape. If more stress is applied to the rock, it bends and flows. It does not return to its original shape. Near the surface, if the stress continues, the rock will fracture (rupture) and break. Choices: - momentum - magnetism - volcanoes - pressure A:
(Answer)
pressure

Ques: Q: What kind of energy is specifically defined as the energy that is available to do work? Read this paragraph and choose the correct option from the provided answers: 6.2 Potential, Kinetic, Free, and Activation Energy Energy comes in many different forms. Objects in motion do physical work, and kinetic energy is the energy of objects in motion. Objects that are not in motion may have the potential to do work, and thus, have potential energy. Molecules also have potential energy because the breaking of molecular bonds has the potential to release energy. Living cells depend on the harvesting of potential energy from molecular bonds to perform work. Free energy is a measure of energy that is available to do work. The free energy of a system changes during energy transfers such as chemical reactions, and this change is referred to as G. The G of a reaction can be negative or positive, meaning that the reaction releases energy or consumes energy, respectively. A reaction with a negative G that gives off energy is called an exergonic reaction. One with a positive G that requires energy input is called an endergonic reaction. Exergonic reactions are said to be spontaneous, because their products have less energy than their reactants. The products of endergonic reactions have a higher energy state than the reactants, and so these are nonspontaneous reactions. However, all reactions (including spontaneous -G reactions) require an initial input of energy in order to reach the transition state, at which they'll proceed. This initial input of energy is called the activation energy. Choices: - used - new - old - free A:
Ans: free

Q: What are plastids that contain other pigments? Read this paragraph and choose the correct option from the provided answers: Chromoplasts are plastids that contain other pigments. These other pigments give flowers and fruits their colors. Choices: - chloroplasts - lucoplasts - cytoplasm - chromoplasts A:
(A).
chromoplasts

Ques:Q: The force of attraction or repulsion between charged particles is called what? Read this paragraph and choose the correct option from the provided answers: When it comes to electric charges, opposites attract. In other words, positive and negative particles are attracted to each other. Like charges, on the other hand, repel each other, so two positive or two negative charges push apart from each other. The force of attraction or repulsion between charged particles is called electric force . It is illustrated in Figure below . The strength of electric force depends on the amount of electric charge and the distance between the charged particles. The larger the charge or the closer together the charges are, the greater is the electric force. Choices: - magnetic force - cooling force - power force - electric force A:

Ans:electric force

Question: Q: Earth's magnetic north and south poles are not the same as what? Read this paragraph and choose the correct option from the provided answers: Earth has north and south magnetic poles like a bar magnet. Earth's magnetic poles are not the same as the geographic poles. Choices: - equatorial planes - geographic currents - geographic hemispheres - geographic poles A:
Answer:
geographic poles
