Due to the need to have completely controlled experiments to test a hypothesis, science can not prove everything. For example, the scientific method cannot alone say that global warming is bad or harmful to the world, as it can only study the objective causes and consequences.
Doctors have not identified a specific cause or result but they think that there are risk factors like:
- advancing age
- family history
-umheathly life style choices
- taking certain medicine
and just in case you did not know what osteoporosis is it is a common disease that weaken the bone and as they weaken you have a higher risk of unexpected fractures
Answer:
Explanation:
Two reactions take place that produce raw materials for the dark stage:
- Light energy splits the water molecules into <em>hydrogen</em> and <em>oxygen</em>
- This process is called <u>photolysis </u>
The hydrogen is taken up by a hydrogen acceptor called Nicotinamide adenine dinucleotide phosphate (NADP) while oxygen is released as a by-product .
2 H₂O(l) --------->light energy -------> 4 H + O₂ (photolysis
)
Light energy strikes the chlorophyll molecules and sets in motion a series of reactions resulting in the production of a high energy molecule called <em>Adenosine Triphosphate</em> (ATP)
Hope this helps.
