Answer:
a gradual increase in the overall temperature of the earth's atmosphere because of the greenhouse effect caused by increased levels of pollutants.
Explanation:
Answer/Explanation: Carbohydrates contain carbon, hydrogen and oxygen atoms with the ratio of hydrogen atoms to oxygen atoms in the ration of 2 hydrogen atoms to 1 oxygen atoms (2H : 10) such as in sucrose or table sugar C12H22011. It is Carbohydrates are a ready source of energy.
The answer is A, Truth
Hope this helped somehow ^-^
Answer:
What would be the expected result of the experiment?
For the drawing of the map part, the scientific will find that effectively, a very large number of volcanoes are located near the meeting points of tectonic plates. The volcanoes that aren't now at the edge of the plate were most probably at the moment of their formation, and were moved away by the movement of the plate.
But I doubt the scientist would be able to identify many new volcanoes, because the creation of a volcano isn't something happening overnight.
How would you interpret the results if the scientist observes no new volcanic activity?
I would say that does NOT invalidate the theory because the observation period is extremely short. 10 years is an insignificant amount of time geologically speaking... the study would have to be conducted over at least 1,000 years to maybe have some results at all. Just imagine how many volcanoes there would be if a new one was created every 10 years along the side of a tectonic plate.
Answer:
The correct answer will be option-D.
Explanation:
Photosynthesis proceeds in two stages: light-dependent and light-independent reaction.
The light-dependent begins when the chlorophyll pigment of the photosystem absorbs light energy. This absorption causes the excitation of the electrons provided by the chlorophyll molecule.
The excited electrons accepted by electron acceptor molecule from reaction center and a chain of electron flow begin called electron transport chain.
This transport of electrons creates a scarcity of electron in photosystem which causes splitting of the water molecule as a result of which oxygen gas is released.
Thus, option-D is the correct answer.
