Lamarck proposed ~ a mechanisms for evolution through the idea of acquired characteristics, which is incorrect Malthus suggested that ~ war, famine, and disease were necessary to keep populations from growing too large Lyell described ~ the Earth as having forces that cause change that occurred in the past and still occurring today Darwin proposed that ~ natural selection as mechanism for how evolution occurs suggesting that the environment selects those alleles best suite...

(from the Greek, meaning cell-eating) involves the formation of an enormous membrane vesicle called a phagosome, or phagocytic vacuole, which engulfs a large particle such as a bacterium. *Only certain kinds of cells can carry out phagocytosis. - Phagocytosis 1. What is the difference between potential and kinetic energy? - -Kinetic energy is energy associated with movement, such as the movement of a baseball bat from one location to another. By comparison, potential energy is the energy th...

What is the endomembranous system? ~ Helps compartmentalize the cell for efficient work. Made of membranes connected directly OR by vesicle transfer. (Also restricts enzyme reactions to certain areas.) Which organelles are involved in the endomembranous system? ~ Endoplasmic reticulum Golgi apparatus Lysosomes Vesicles What is a peroxisome? ~ Specialized (cell specific) vesicle enzymes. Detoxify (alcohol, etc.), process and destroy free radicals. What is a vacuole? ~ memb...
