BSC 1005 Lecture Notes - Lecture 28: Vacuole, Chemical Energy, Archaea
Document Summary
The ability of the body or cell to seek and maintain a condition within its internal changes despite the external changes. Properties of life: high order, regulation, growth and development, use of energy, respond to environment, evolve, reproduce. Hierarchy of life: atom, molecule, organelle, cell, tissue, organ, organ system, organisms, population, community, ecosystem. Organisms who are better suit for an environment and reproduce causing their population to increase. Antibiotic resistance: huge problem in public health, more selectively, multiply and become the norm. Gain or lose electrons to fill valence shell. Chemical energy storage in the bonds of chemical compounds. Dna and rna carry genetic blueprint of a cell and carry instructions for the functioning of the cell. Chemical signaling molecules secreted by a gland that act to control or regulate a specific process. Enzyme (proteins) that act as catalysts and help complex reactions occur everywhere in life. Organelles tiny structures that perform specific functions within cell nucleus, er, chloroplasts.
