The 10% energy rule means that when energy is passed into the ecosystem from one trophic level into the next, only ten percent energy will be passed on.
Answer:
A molecule with hydrogen bonded to to O, N, or F
Explanation:
Apex approved
B. It converts glucose into energy.
C. It controls the way your body uses calcium.
D. It effectively rehydrates the system
Answer:
C.
Explanation:
Vitamin D is a molecule that is essential in the transport of the Calcium to the bones, it can be obtained from direct contact with the sun or can be obtained directly from the diet. Besides transporting the Calcium to the bones, also participates in regulation of calcium and fosfate in the kidneys and intestine promoting the calcium reabsortion at renal level and calcium absortion at intestinal level. Also modulates the inmune system, promoting the maturation of monocytes to macrophages, improving the inmune response.
Answer:
The heat of vaporization relates the amount of heat required to transform a certain phase of a certain amount of substance from liquid to gas. The heat of vaporization of substances can be expressed in terms of joules per gram or joules per mole.
ExplanaDetermine the total amount of heat, q, that is required to evaporate the given amount of water at its boiling point. For this problem, we simply apply the equation,q

Answer:
1. Considering the massive size of the structures, it is improbable to think that man is actually capable of building them.
2. And the intelligence and calculations needed for this construction is beyond the capacity of man, considering the age and times of the ancient Egyptians.
Explanation:
While Egyptologists and historians have, through years and years of research, have found evidence that it was actually the Egyptians that built them, there are also some people who held the belief that they are actually made and constructed by aliens. The humans of the ancient time that these structures were constructed were incapable of having the intelligent power and manpower and strength to carry out these works, with big blocks of stones and massive heavy structures to be made. However, the article "Who Built The Pyramids" shows the findings of Egyptologists Mark Lehner and Zahi Hawass who has worked to uncover the truth about these massive buildings of ancient years, trying to prove who actually built and how. They argued that, with all the workforce needed to actually bring about the construction of these structures, it is evident that the people of Egypt indeed were the workers and builders of these structures, and that too not as slaves (unlike many claims) but more as a sense of obligation to the king. And to refute the alien builder theory, there are definite proof that shows that it is humans and not aliens who built it. There are settlements that housed the workers, bone remains that have been examined by scientists and doctors, who have proved that humans and not aliens are the workers. Added to it, there seem to be no findings or even a shred of evidence too prove aliens have indeed been there, let alone construct that. Considering the massive structure of the pyramids, it is probable to think that man is incapable of constructing something like these, but like Lehner and Hawass has pointed out, there are lots of evidences to prove man actually built them. But there are still other group of theorists and believers that thinks aliens and not humans built them.
Answer:
Those who support the alien theory believe that the ancient Egyptians were very primitive. They argue that no blueprints of the pyramids have been found and that moving two-ton stones would have required alien technology.
