1. One reason is extinctions happen because of some kind of change in the environment where a life form lives. While some species can adapt to the changes, others die, and if enough die, the species becomes extinct. These are some of the biggest factors in the extinctions of particular species. 2. Contaminants in the environment, such as pesticides.
The best answer would be:
Osteoarthritis
<span>It is when the person experiences too much weight bearing activities, which may cause the wear and tear breakdown of the joints. This worn bone may be a foreign material when identifying the joint erosion.</span>
The right answer is It does not show that photosynthesis consists of many separate reactions.
It takes six molecules of carbon dioxide and six molecules of water to synthesize a molecule of glucose, releasing six molecules of oxygen, thanks to the light energy.
6 CO2 + 6 H2O + light energy ==> C6H12O6 (glucose) + 6 O2
<u>But this balance is in fact broken down into two successive stages:</u>
Light phase or photochemical phase:
12 H2O + light ==> 6 O2 + chemical energy (24 H).
The Calvin cycle (dark phase):
6 CO2 + chemical energy (24 H) ==> C6H12O6 + 6 H2O.
