Biology Exam 2013 - Review UNIT: PATERNS OF INHERITENCE Describe Mendel’s experiments: * Chose a female parent; chooses a male parent; pollen is collected from the stamens and dusted onto the female parent stigma; pollen fertilizes the eggs. The ovary develops into the pod and eggs develop into the peas; when peas are planted they develop into pea plants. Why Pea Plants? * Easily obtained * Grown quickly; several generation of peas can be observed * Traits are easily visible

Biodiversity is the degree of variation of life forms within a given ecosystem‚ biome‚ or an entire planet. Biodiversity is one measure of the health of ecosystems. Life on Earth today consists of many millions of distinct biological species. The United Nations declared the year 2010 as the International Year of Biodiversity. Biodiversity is not consistent across the Earth. In the terrestrial context for example‚ tropical regions are typically rich whereas polar regions support fewer species. Rapid

BSC2011C Final Review Unit 1 Review Ch. 25‚ 22‚ 23‚ 24‚ 26‚ 19‚ 27 Ch. 25 1. Life is metabolism and heredity. Metabolism is the mechanism that creates order and complexity from chaos‚ by acquiring and expending energy. Heredity is the ability of an organism to copy itself and it is broken down into: i. Multiplication‚ ii. Inheritance‚ iii. Variation. 2. DNA codes via RNA for 20 of naturally occurring amino acids. Amino Acids are the building blocks of proteins and bodies. DNA stores and transmits

Characteristics and Properties of Amino Acids Introduction: Each amino acid has at least one amine and one acid functional group as the name implies. The different properties result from variations in the structures of different R groups. The R group is often referred to as the amino acid side chain. Amino acids have special common names‚ however‚ a three letter abbreviation for the name is used most of the time. A second abbreviation ‚ single letter‚ is used in long protein structures.Consult
