"The first and second hominids were able to mate and produce offspring, but the first and third hominids could not." <span>Although that might be the case, it might also not. "More similar" needn't be 'similar enough' (disregarding the fact that all homonid specimens involved could happen to share the same sex). </span>
<span>"The first and second hominids shared the same geographic location, while the third was isolated." </span>
<span>That information would be revealed by the geographic location they came from. </span>
<span>"The first and second hominids most likely became extinct before the third hominid species." </span>
<span>Perhaps or perhaps not. As ancestral lineages can survive for longer than descendant lineages, it needn't apply. Still, I suppose the non-existent law of averages provides some sort of justification for the use of "Most likely". </span>
<span>"The first and second hominids have a more recent common ancestor than the first and third hominids." </span>
<span>Assuming these are all in the same neat lineage, then the most recent common ancestor of the first and second is also the most recent common ancestor of the first and the third.</span>
The answer is true light is one of the forms of electromagnetic energy.
Answer:
Cell division results in daughter cells that contain DNA. Each daughter cell has two complete sets of chromosomes. Within a cell, two chromosomes pair up and exchange segments of genetic material.

Answer:
b. Their presence is evidence of a defect in DNA replication, and therefore proof that a given disease is present
Explanation:
Single nucleotide polymorphisms (SNPs) result from point mutations and correspond to the position where there is alternation of nucleotides A, C, G, T at a minimum allele frequency of 1% in a given population. SNPs can be present in both coding and non-coding regions of the genome. As a nucleotide alternation is the result of a defect in DNA replication and these defects cause syndromes and diseases; we can say that single nucleotide polymorphisms are evidence of a defect in DNA replication and therefore proof that a particular disease is present.
