Why are chemoautotrophs rare among familiar organisms?

Concepts of Biology 1
What is the difference between micro- and macroevolution? a. Microevolution describes the evolution of small organisms, such as insects, while macroevolution describes the evolution of large organisms, like people and elephants. b. Microevolution describes the evolution of microscopic entities, such

Consider a state with a fixed prison capacity of 1,000. When a law is passed establishing a minimum term of 10 years, (twice the current average term), the state cuts the number of prisoners in half, cutting the probability of imprison- ment for crime in half. Use a graph like Figure 133 to illustrat
