Unformatted text preview: available in the zygote cells. Later in life the energy must be acquired, but at first a sort of inheritance/trust fund of energy is used. Cells range in size from small bacteria to large, unfertilized eggs laid by birds and dinosaurs. The realtive size ranges of biological things is shown in Figure 1. In science we use the metric system for measuring. Here are some measurements and convesrions that will aid your understanding of biology. 1 meter = 100 cm = 1,000 mm = 1,000,000 µm = 1,000,000,000 nm 1 centimenter (cm) = 1/100 meter = 10 mm 1 millimeter (mm) = 1/1000 meter = 1/10 cm 1 micrometer ( µ m) = 1/1,000,000 meter = 1/10,000 cm 1 nanometer (nm) = 1/1,000,000,000 meter = 1/10,000,000 cm...
