Explanation:
Four relatively recent fossil species were recovered, and when the DNA was extracted, investigators observed that Species W and Z both had long finger bones, and species X and Y had short finger bones. Based upon this information and the hypothetical molecular data below, sequenced from common regions in one gene of their DNA, which two species are the most closely related to each other?
Species W:
AACATTGCTT
TTGTAACGAA
Species X:
AACCGCGCGT
TTGGCGCGCA
Species Y:
AGCAGCGCTT
TCGTCGCGAA
Species Z:
AACCGCGCTT
TTGGCGCGAA
A) Species X and Z
B) Species W and Z
C) Species Y and Z
D) Species X and Y
Answer:
A) Species X and Z
Explanation:
When comparing DNI sequences, you can see that the individuals with the most similar chains are X and Z. They only differ in the penultimate pair of bases. Species X carries guanine-cytosine pair, while species Z carries the Timin-Adenine pair.
Species X: Species Z:
AACCGCGCGT AACCGCGCTT

Answer:
circle the brighter (yellow / red) areas, the are hotter, so we can expect more stars there.
the darker (blue / dark blue) areas are colder, do we expect less dense mattet/stars
since the areas are overall equal in energy density (note that the different color represent very little difference in temperature), we can expect a common origin, because regions of space so vastly apart couldn't possibly smooth out later, they would be to far apart.
