The illustration below indicates that photosynthesis and cellular respiration are both complementary and balanced.An excess of sugars produced fossil fuels like coal and petroleum; this suggests that in the past,
Photosynthesis and cellular respiration are both complementary and relatively balanced,but early history of life on Earth showed increasing oxygen concentrations.This indicates that
Each time a person takes a breath,he or she is bringing in the oxygen he or she needs to stay alive.The ultimate source of the oxygen used by all aerobic organisms comes from a reaction that breaks down
What would be the initial outcome of decreasing the number of photosynthetic organisms on Earth with no change in the number of organisms using cellular respiration?
Plants and animals use different energy storage molecules,yet they both use the same mechanism to "burn" their stored energy.How can plants and animals both be successful,even though they "burn" different energy storage molecules?
A worker is paid every two weeks.She uses some of this money to pay for essentials and puts the remainder of her money in a savings account at a bank.The money the worker saves is analogous to the
