1. is the process of sensing and adjusting to change by keeping
conditions in the internal environment within a range that favors survival.
2. is a system of naming and classifying species.
3. is a hypothesis that is consistent with all data ever gathered and can be
used to make successful predictions about other phenomena.
4. is the evolutionary history of a species or a group of them.
5. is the study of patterns in the geographic distribution of species and
6. is defined as the degree of adaptation to a specific environment, and it is
measured as the relative genetic contribution to future generations.
7. In cells, DNA molecules and their associated proteins form structures called
8. Converting the information encoded by a gene into its product starts with RNA
synthesis, or , during which enzymes use the gene’s DNA sequence as
template to assemble a strand of RNA.
9. is a process by which a chromosome and its homologous partner
exchange corresponding pieces of DNA during meiosis.
