Answer the following question given this paragraph: Grazers, such as sea urchins, are organisms that feed on available plants. Sea urchins are omnivorous, eating both plant and animals. The sea urchin mainly feeds on algae on the coral and rocks, along with decomposing matter such as dead fish, mussels, sponges, and barnacles. Q: What are organisms that feed on available plants called? Choices: - florophores - plantfeeders - antigens - grazers A:
grazers

Answer the following question given this paragraph: The cavities normally contain hydrated cations that are loosely bound to the oxygen atoms of the negatively charged framework by electrostatic interactions. The sizes and arrangements of the channels and cavities differ in different types of zeolites. For example, in zeolite A the aluminosilicate cages are arranged in a cubic fashion, and the channels connecting the cavities intersect at right angles. In contrast, the cavities in faujasite are much larger, and the channels intersect at 120 angles. In these idealized models, the oxygen atoms that connect each pair of silicon atoms have been omitted. Silicon and germanium react with nitrogen at high temperature to form nitrides(M3N4): Equation 22.26. Q: Silicon and germanium react with nitrogen at high temperature to form what? Choices: - oxides - carbonates - isotopes - nitrides A:
(Answer)
nitrides
Ques: Answer the following question given this paragraph: The electrochemical potential across a membrane determines the tendency of an ion to cross the membrane. The membrane may be that of a cell or organelle or other sub cellular compartment. The electrochemical potential arises from three factors:. Q: The electrochemical potential across a membrane determines the tendency of an ion to do what? Choices: - attach to the membrane - move away from the membrane - destroy the membrane - cross the membrane A:
Ans: cross the membrane
(Q).
Answer the following question given this paragraph: Identify evidence for electroweak unification. The quarks in a particle are confined, meaning individual quarks cannot be directly observed. Are gluons confined as well? Explain. Q: The quarks in a particle are confined, meaning individual quarks cannot be what? Choices: - separated - changed - hypothesized - directly observed A:
(A).
directly observed
Ques:Answer the following question given this paragraph: Q: What are the poles labeled? Choices: - west and south - southwest and south - east and west - north and south A:

Ans:north and south
Answer the following question given this paragraph: An ecosystem consists of all the living things ( biotic factors ) in a given area, together with the nonliving environment ( abiotic factors ). The nonliving environment includes water, sunlight, soil, and other physical factors. Q: An ecosystem consists of all the living things and what? Choices: - living environment - phosphorescent environment - local environment - nonliving environment A:
nonliving environment
