Answer the following question given this paragraph: Figure 8.11 The sun emits energy in the form of electromagnetic radiation. This radiation exists at different wavelengths, each of which has its own characteristic energy. All electromagnetic radiation, including visible light, is characterized by its wavelength. Q: What form of radiation is the energy emitted by the sun? Choices: - seismic - magnetic - thermal - electromagnetic A:
electromagnetic
Answer the following question given this paragraph: Water is involved in many biochemical reactions. As a result, just about all life processes depend on water. Q: Just about all life processes depend on what? Choices: - air - carbon - meat - water A:
water
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? Choices: - catalysts - oxides - isotopes - cations A:
A: cations

Answer the following question given this paragraph: Predation is a relationship in which members of one species consume members of another species. The consuming species is called the predator. The species that is consumed is called the prey. In Figure below , the wolves are predators, and the moose is their prey. Q: What do you call the relationship in which members of one species consume members of another species? Choices: - parasitism - competition - exploitation - predation A:
predation
