Genes come in different varieties, called alleles<span>. </span>Somatic cells<span> contain two alleles for every gene, with one allele provided by each parent of an organism. It is impossible to tell exactly what gene the organism could have. </span>
<span>Although a star might look brighter than the Sun, a comparison of its absolute<span> magnitude might help prove that they have the same real brightness.
Absolute magnitude is a concept that compares the absolute brightness of celestial objects. The absolute magnitude of an object is defined as the apparent magnitude it would have if it were viewed at a standard distance of 10 parsecs (32.6 light-years) with no dimming of its light. The more luminous an object, the smaller the numerical value of its absolute magnitude.</span></span>

We know that arteries from the aorta and arteries from coronary arteries supply oxygenated blood to various parts of the body. What separates these two is the coronary arteries’ ability to deliver oxygenated blood to the heart.
We know that the inferior vena cava delivers deoxygenated blood to the lower (hence inferior) part of the body and that the superior vena cava delivers deoxygenated blood to the upper (superior) part of the body; they follow the same deoxygenated rule and strictly deliver nutrients to certain parts of the body.
I hope I helped! :)
