Unit 2A - Characteristics and Requirements of Life

State Goal Content

The Eight Characteristics of Life: Pasteur, Spalanzine, Redi, Spontaneous Generation. Requirements for Life: Transport (how organisms get what they need to cells, how they move waste from cells to organs of excretions. Excretion – how organisms get rid of their waste and balance their fluids (pH, salt concentration, water). Regulation – how organisms control body processes – hormones, nervous system). Respiration – how organisms get oxygen from the environment and release carbon dioxide back to the environment and how plants exchange gases. Nutrition – How organisms break down and absorb foods. Synthesis – how organisms build necessary molecules. Reproduction – sexual vs asexual, eggs, seeds, spores, placental, types of fertilization. Growth and Development – metamorphosis, development in egg or in uterous, growth from seed or spore. Feeding adaptations. Adaptations to ensure successful reproduction. Other Adaptations: Mimicry, Camouflage, etc.

Written Explanation

This is Where I would put a written explanation of the objectives, like would be in a text book.

Journal Reading

Nanotechnology The issue-focused, peer-reviewed article demonstrates how nanotechnology, or the rearrangement of atoms to manufacture products, has incredible potential. For example: computers with massive memory but miniscule storage devices, airplanes and other transport made from lightweight material, and medical instruments that can operate on cells or genes. THIS
IS SUPPOSED TO BE IN THE GENERAL CHEMISTRY UNIT!!
