Evolution over time has allowed them to adjust to their surroundings. Birds can also survive on eating less/smaller things whereas reptiles usually have to eat more to survive. Also, birds eat a lot of plants while reptiles eat a lot of meat.
The diaphragm,
During inhalation, the diaphragm is contracted which increases the volume of the lung cavity. During exhalation, the diaphragm is relaxed which decreases the volume of the lung cavity
It is necessary to phosphorylate a glucose molecule so as to trap glucose inside the cell, to make ATP, and to facilitate enzyme building. When insulin is released from the pancreas after a meal, it signals the tissues to uptake glucose. When glucose enters the cells via glucose transporters, there is a chance for them to leave the cell. If the body is in need of energy, and the breakdown of glucose will provide that energy, the body does not want the glucose to leave the cell and that is why the glucose is phosphorylated by ATP to become glucose-6-phosphate, which now bears a charge.

Well, scientists depend on science.They use the process of observation. But there are processes for these. The processes are;
Asking a question; Scientists wonder how specific happenings can be explained, they look for an answer.
They perform research; the scientists study the particular thing, and look for reasons for a particular happening.
They form a hypothesis; a hypothesis is a statement which is not universally true, they are observations that haven't been agreed upon.
They test their hypothesis; they perform experiments to find out if their hypothesis is true.
They analyse the data and draw a conclusion; they record their hypothesis and write down their end result.
They pass across their result; they pass their new observation across to other people.
Hope i helped. Have a nice day.
