Definitely D. Because we just learned about this in science
Trees produce oxygen in order for us to breathe. if we cut them down there is less oxygen for us.
in an area of wildlife many different animals survive off of trees. cutting down the trees could lead to the extinction of specific animals.
Answer:
Differences between aerobic and anaerobic respiration is whether or not oxygen is present. . During aerobic respiration, carbon dioxide, water, and ATP are produced. During anaerobic respiration, lactic acid, ethanol, and ATP are create, aerobic os used when heart rate and breathing rate rise, anaerobic is used during the first 1-2 mins of exercise, occurs in the cytoplasm of cells, while aerobic occurs in the mitochondria of the cells, glycolysis occurs in both, both are respiration, and both create ATP
Explanation:
13-13= 0, 19-13= 6, so then 0-6= -6
