Answer:
late 14c., "fill with disease, render pestilential; pollute, contaminate; to corrupt morally," from Latin infectus, past participle of inficere "to stain, tinge, dye," also "to corrupt, stain, spoil," literally "to put in to, dip into," from in- "in" (from PIE root *en "in") + facere "to make, do, perform" (from PIE root *dhe- "to set, put").
Explanation:
This is because maybe that allele for the trait is recessive and the person is heterozygous.
If the person is heterozygous, it means that they have both the dominant and recessive allele for a trait. And by dominant and recessive, if dominant allele exists, no matter if recessive allele exists or not, the characteristic controlled by the dominant allele must be shown. This is their phenotype, which is the observable characteristics.
For example, there are 2 alleles for controlling the eye color. Brown allele is dominant, while blue is recessive. Just like the question above, if the person has an allele for blue eye color, but they have the brown color allele too, their phenotype would be brown eye color, as the brown color is dominant over blue eye color. This matches the requirements of having the allele for a particular trait but not showing the phenotype of that.
Answer:
Nitrogen thet cannot be used by organisms. C.
Explanation:
Free nitrogen is simply molecular nitrogen (N2). Nitrogen, in its molecular form, consists of two nitrogen atoms bound together with a tripple bond. Because it is very stable, N2 is typically nonreactive, and takes a lot of energy to break them apart. Among these are the amino acids necessary for life to begin and which are the building blocks DNA is made from. Basically, any nitrogen that is in an organic compound is considered “fixed” nitrogen and N2 is considered to be “free” nitrogen
In general cells that need more energy, since mithocondria are responsible for making and processing ATP.
Common examples of cells with many mithocondria are muscle cells that are in current activity all the time, specially heart muscles and muslces in the respiratory system such as the diafragma since the heart beats all the time, non-stop, that is, unless you die of course and so do the muslces needed to breath.
