Excess nutrients stimulate Decomposition uses up Low oxygen levels, called "hypoxia", cause shellfish to die, and algae blooms. dissolved oxygen in Bay. fish and crabs to leave habitat or die treating "dead zones". The figure above shows what happens when human-created pollution ends up in the Chesapeake Bay. Explain how low oxygen levels (hypoxia) affect the ability of fish to get the energy needed for life processes. Use cellular (aerobic) respiration, oxygen and ATP in your response

The skeletal system performs a variety of functions that are crucial to maintaining life processes. what function is performed in the bone marrow, but not in the ossified bones of the skeleton? a oxygen transportation c mineral storage b. muscle attachment d red blood cell production

Animal bodies (and even plant bodies for that matter) are complex enough that life couldn't exist without enzymes. enzymes are usually large, complex biological catalysts that are expensive to make. enzymes speed up the rate of chemical reactions without being used up during the reaction (they can be reused many times). they are highly specific in the reactions they regulate. knowing what enzymes are and how they function, why does this explain why complex life forms could not exist if there were no enzymes.
