You would need a direction to determine the velocity because velocity is speed with a direction. 40km/h is just speed.
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

Answer: Erythropoiesis is the process which produces red blood cells (erythrocytes). It is stimulated by decreasing oxygen in circulation detected by the kidney which then secrete erythropoietin that proliferate and differentiate red blood precursors & produce red blood cells.
Explanation: The use of erythropoietin to boost red blood cells is called blood doping. The more red blood cells are present in the body, the more the energy expenditure and the slower you will burn calories during physical activities.
B continue to produce oxygen
Explanation:
carbon will not reduce to synthesise sugars
