2. When organisms break the bonds of organic compounds, the organisms can
(1) use the smaller molecules to plug the gaps in the
cell membrane to slow diffusion
(2) use the energy obtained to digest molecules
produced by respiration that uses oxygen
(3) obtain energy or reassemble the resulting
materials to form different compounds
(4) excrete smaller amounts of solid waste materials
during vigorous exercise

meiosis is the correct answer

not necessarily. higher fitness requires the organism to be reproductive successful. for example, an organism at age 10 with 15 offspring is much more fit than an organism at age 15 with only 5 offspring.

one part of the electromagnetic spectrum that arrives on earth as solar radiation from the sun is the visible spectrum. wavelengths of the visible spectrum combine to form what we refer to as

answer - d) ultraviolet radiation.

violet /   380–450 nm / 668–789 thz

violet is number 1 in the chart of visible light.

imagine a line passing through the center of earth that goes through both the north pole and the south pole. this imaginary line is called an axis. earth spins around its axis, just as a top spins around its spindle. this spinning movement is called earth's rotation. at the same time that the earth spins on its axis, it also orbits, or revolves around the sun. this movement is called revolution.
