Yes it is absolutely true that each lung is fed oxygen by a separate bronchus. There are actually two lungs and two bronchi. Each of the two lungs are safeguarded by the two ribcages as
they are placed within the rib cages. The lungs actually consists of elastic
sacs that contract and expand for taking in and releasing air. This way oxygen
is passed into the blood and carbon dioxide is taken out from the blood and
passed out. This is also the main function of the lungs.
Answer:
Some of the hydrogen bonds with other elements, but most of it remains free hydrogen. Both hydrogen and helium are light elements, so they will tend to evaporate into space over time. ... But the gravity of Earth isn't strong enough, so Earth's early atmosphere of helium and free hydrogen evaporated into space.

Answer:
The answer is letter D
Explanation:
<em>The set point is the weight range in which your body is programmed to function optimally. Set point theory affirms that an indivual's body will fight to mantain that weight range. Evebody is biologically and genetically determined to weigh within a certain weight range. Set points will vary for each individual person. </em>
<em>Scientists estimate that the average person has a set point range about ten to twenty pound rage at which your body will be comfortable and not resist attempts to change.</em>
Answer:
The correct answer is A protein production can occur much faster in prokaryotic cell since the cell does not have to get the message stored in the DNA out of the nucleus.
Explanation:
protein biosynthesis or translation occur in both Prokaryotes and Eukaryotes.
In prokaryotic cell both transcription and translation occur inside the nucleus but in case of Eukaryotic cell transcription occur in the nucleus whereas translation occur in the cytoplasm.
In case of eukaryotic cell mRNA processing occurs which involves 5 prime capping, 3 prime tailing and splicing but in case prokaryotic cell no such processing occurs.
As a result protein production occur much faster in prokaryotic cell than that of eukaryotic cell.
Evolutionary biologist hope this helps
