Explanation:
An ORE is the naturally occurring form of a particular element, from which the element can be EXTRACTED and further purified for commercial or other uses.
So, Bauxite is the principal ORE of aluminium in NATURE. It is a clay-like mineral, being a mixture of hydrated oxides and hydroxides. An example is (Al(OH)3)
Thus, Alcoa controlled the supply of bauxite in the United States before the World War II IN ORDER TO ensure the continuous availability of aluminum

Y-linked genes are linked to the Y chromosome. They are not as usual as the X-linked genes and can only be expressed by men or males. Sons' phenotype: 100% hairy ears. Daughters' phenotype: 100% not hairy ears.
<h3>
What are sex-liked genes?</h3>
When talking about sex-linked genes, we refer to genes located in one of the sex chromosomes.
Being linked to one of the sex chromosomes means that these genes, and their corresponding alleles, will only be inherited together with the chromosome.
In general, genes are linked to the X chromosome. These are X-linked genes. In these cases, a male that inherits the X chromosome from a heterozygous female can express either the dominant or the recessive trait, depending on which allele it got from the mother.
However, some genes are linked to the Y chromosome and hence, inherited only by males or men. Traits coded by Y-linked genes will only be inherited by males.
In the exposed example, we are referring to an Y-linked gene, so it will only be inherited by sons and not daughters.
- Expected phenotypes of the man's sons ⇒ 100% haired ears
- Expected phenotypes of the man's daughter ⇒ 100% not haired ears
