The molecule of water is different from the molecules of oxygen and hydrogen in the following ways:
1. Combustion: Oxygen supports combustion, hydrogen burns in the air to form water. Water is not combustible. It rather inhibits combustion when poured over burning substances.
2. State of matter: Water is a liquid in room temperature whereas oxygen and hydrogen are gases. The polar nature of water contributes to hydrogen bonding between the hydrogen and oxygen atoms of water.
3. Density: Water is denser than both oxygen and hydrogen. Hydrogen bonding helps pack more molecules of water in less space.
4. Freezing point: Water freezes to ice at 0°C whereas oxygen freezes at -218°C and hydrogen freezes at -259°C.
Answer:
If an individual has a dominant phenotype it is not known what the exact genotype is. For example with the phenotype of brown eye color , the genotype could be heterozygous.
Explanation:
Dominant is a trait that shows dominance over a recessive trait. The dominant trait might have a heterozygous or homozygous genotype.
For example, if the brown eye is a dominant phenotype, it might be that a person might have a heterozygous genotype for this trait. One of the alleles might be the dominant one while the other allele might be recessive. In such a case, the effect of the recessive trait is masked by the dominant trait. Hence, the organism shows the dominant phenotype but has a heterozygous genotype.
