Name and describe two important attributes of life.
1. Reproduction (giggity ^.~): is when traits are passed from one generation to the next, which can be sexual or asexual.
2. Metabolism: is using molecules from the environment for maintenance and growth
Explain the difference between a theory and a hypothesis.
hypothesis is a tentative answer/testable solution to a well framed question. theory is a well supported hypothesis that links together a large body of observations
Explain the difference between hypothesis and its predictions
Hypotheses are proposed explanations for specific phenomena or observations and are testable with controlled observations and/or experiments and thus generate predictions. Predictions are measurable, must be correct for hypothesis to be true, and are often phrased as "if..., then...." statements
What evidence supported the cell theory?
Pasteur tested the competing hypothesis of "cells rise from pre-existing cells" by doing Pasteur's experiment.
Explain why replication and control are important to experiments.
Elements of successful tests are replication and controls. Replication accounts for variation in observations and results while control checks for factors other than the one of experimental interest that might affect outcome.
How did Darwin formulate his theory of evolution via natural selection? How were the following relevant to him: variation, inheritance patterns, and population growth?
Darwin proposed the theory of natural selection as a process to explain evolution through observation and fact. His Key components are that organisms in a population vary in traits, at least some of the traits are heritable, more offspring will be born than can survive, survival is not random, and certain heritable traits promote survival. These traits will be favored by natural selection. "differential success"
