Answer:
While Americans constitute the 5% of the world population, they use around the 24% of the world's energy.
Then, if the 100% of the population were like the Americans, we have:
5%*x = 100%
x = 100%/5% = 20
the whole population is 20 times the population of the US, then the total energy used is 20 times the energy used in the US.
Then the energy that the 100% of the population would use is equal to:
20*24% = 480%
Sowe actually would need like 5 Earths.
So none of the options is matches this, but this may be because this question is about some specific resources and not for the specific energy used. The closest option is 200%
The Object Masses, will affect the force of gravity between the two objects, and the distance between the objects will affect the force of gravity between the two objects.
Answer: The basic theme of whale evolution is the development of large animals from much smaller ancestors, and nowhere is this more evident than in the case of multi-ton sperm and gray whales, whose ultimate forebears were small, dog-sized prehistoric mammals that prowled the riverbeds of central Asia 50 million years ago. Perhaps more intriguingly, whales are also a case study in the gradual evolution of mammals from fully terrestrial to fully marine lifestyles, with corresponding adaptations (elongated bodies, webbed feet, blowholes, etc.) at various key intervals along the way.
Explanation:Pick B is the best choice
Answer and explanation;
-The most important life processes in the oceans or sea water are photosynthesis and respiration. Photosynthesis by plants and other lower organisms uses sunlight to convert CO2 and H2O to a carbohydrate compound; O2 is a by-product of that reaction. Respiration is the process that all organisms use to recover the chemical energy stored in organic compounds. O2 is used to oxidize organic matter and release chemical energy; CO2 and H2O are by-products.
-The rates of photosynthesis and respiration are nearly balanced.all of the organic matter produced by photosynthetic algae is respired by consumer and decomposing organisms.
An hypothesis is an educated guess whereas a theory has supporting evidence to help prove the point to be correct. (I THINK this is right)
