The hotter an object is, the faster the motion of the molecules inside it. Thus, the heat of an object is the total energy of all the molecular motion inside that object. Temperature, on the other hand, is a measure of the average heat or thermal energy of the molecules in a substance. please verify answer!
He should get his mitochondrial haplotype sequenced, given the genetic variation in mitochondrial sequences compared to Y chromosomes.
Explanation:
Mitochondrial DNA haplotypes are specific regions of mitochondrial DNA that cluster with other mitochondrial sequences to show the phylogenetic origins of maternal lineages.
Mitochondrial DNA haplotypes are associated with a range of phenotypes and disease.
Mitochondrial DNA contains 37 genes, all of which are essential for normal mitochondrial function.
Thirteen of these genes provide instructions for making enzymes involved in oxidative phosphorylation.
<em>"In abrasion, one rock bumps against another rock. Gravity causes abrasion as a rock tumbles down a mountainside or cliff. Moving water causes abrasion as particles in the water collide and bump against one another."</em>
