Answer:
As SpaceX started winning more and more NASA contracts, NASA saved more and more of its limited budget. The second key innovation to the aerospace industry that SpaceX made was the programming of self-landing boosters. The Falcon 9 booster has the ability to land itself autonomously which allows for rapid reusability
1. Balances fluids.
2. Structure. Support for tissues.
The correct answer is the lungs. Usually, in the systemic organs such as the liver, kidneys, and the heart; hypoxia or low oxygen levels cause the blood vessels supplying them to vasodilate to increase flow of blood and prevent ischemia. Adequate oxygenation of systemic organs cause the blood supply to vasoconstrict to prevent pooling of oxygenated blood and shunt it to other organs that need the oxygen more.
However, in the lungs, the opposite is true because in the setting of hypoxia, the blood vessels of the lungs vasoconstrict as to shunt the blood to other parts of the lungs with adequate oxygenation for the blood to be adequately oxygenated. If there is adequate oxygen in the lungs, then blood vessels vasodilate to efficiently get the oxygen from the lungs.
Answer:
The correct answer would be the experimental group.
There are mainly two groups present in any experiment; the experimental group and the control group.
The experimental group refers to the group which receives experimental procedures or is exposed to the independent variables to be tested.
In contrast, the control group refers to the group which is kept in controlled conditions, that is, it is not exposed to the variables which are being tested.
