What is the goal of bioremediation? - To clean up areas polluted with toxic compounds using bacteria Broad-spectrum antibiotics inhibit the growth of most intestinal bacteria. Consequently, assuming that nothing is done to counter the reduction of intestinal bacteria, a hospital patient who is receiving broadspectrum antibiotics is most likely to become - deficient in certain vitamins and nutrients If prokaryotes did not exist, what would change in the nitrogen cycle? - The rate of movement ...

charophytes - (aquatic) green algae land plants evolved from 3 key traits land plants share with charophytes - 1. rings of cellulose-synthesizing proteins embedded in plasma membrane 2. formation of a phragmoplast (helps form cell wall) 3. structure of flagellated sperm (not all will have this) adaptations enabling plants' move to land: why? - 1. CO2 2. sunlight 3. soil- nutrients 4. fewer predators/pathogens (never been seen before) adaptations enabling plants' move to land: problems...
