The given question is incorrect. The correct question is:
Question: When the diaphragm contracts, _______.
A) it lifts the rib cage
B) it rises in the thoracic cavity
C) it flattens out
D) it flattens out and it rises in the thoracic cavity
Answer:
C) it flattens out
Explanation:
The diaphragm is a muscular dome-shaped structure. It contracts and relaxes during inhalation and exhalation respectively. During normal and quiet inhalation, the diaphragm and external intercostal muscles contract. The contraction of the diaphragm makes it flat to increase the volume of the thoracic cavity. This allows the lungs to expand and the pulmonary air pressure is reduced. The atmospheric air moves into the lungs.
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%
They are better adapted to the environment. Their darker color helps them blend in with the tree bark so common in their habitat. Because of that, more are likely to not get eaten by predators than white ones that are so easy to spot without camouflage abilities. The black moths are simply more fit to survive, and more of them will survive in this place.
