<span>I think one cannot really separate the lack of oxygen from air pressure. Because the inside pressure balance the outside pressure, if the pressure is low outside, one cannot inhale lots of air without lung injury. Similarly, a scuba diver always inhale air at the pressure associated with its depth. (In consequence divers absorb much more oxygen (and consume more air) in deep water than in shallow water). You may eventually separate air pressure from oxygen if you consider someone who put a single arm or leg in a artificially very low pressure environment</span>
Explanation:
Plants that are denied sufficient light will eventually lose their color and die. Plants deprived of light will grow upward, stretching their stems more rapidly that usual, searching for light. This process is known as etiolation and is a survival mechanism that maximizes the plant's chances of getting to light.
Answer:
Tasters” report that the strip tastes very bitter, while “nontasters” may only detect a small amount of bitterness, if at all. The ability to taste PTC is due changes in the TAS2R38 gene that affects the function of bitter taste receptors on the tongue.
The version of the gene that allows tasting of PTC is masked if it is paired with the version of the gene that does not allow tasting. Traits could come from either parents. A person will only get a bitter taste from PTC if they inherit a copy of the gene for tasting PTC from both of their parents. Some people will have different genotype. so some people may have it Therefore in a family tree , only the grandfather and the youngest daughter can taste PTC.
