The number of years of divergence from a common ancestor =300,000 years.
<h3>What are mutations?</h3>
Mutations are changes that occur in the DNA of living organisms.
Mutations can be used as molecular clocks if they occur at a constant rate.
Considering the nucleotide substitutions occur by mistake in a segment of ribosomal RNA at a constant rate of one substitution every 100,000 years.
The ribosomal RNA of the two modern-day species have six differences in their sequences.
Number of years of divergence = 6/2 * 100000 = 300,000 years.
In conclusion, changes that occur in nucleotide sequences are known as mutations.

"At the end of anaphase, there is one cell with 20 chromosomes - 10 chromosomes at one end of the cell, and 10 chromosomes at the other end. Upon completion of telophase and cytokinesis, the single cell will be split into two cells. Each cell will contain 10 chromosomes, the same amount as the original progenitor cell."

The sentence that best explains why the native Australian dung beetles were not doing the job is "Cow dung is not part of any native Australian species niche." The beetles in Australia had formed alongside the kangaroos and wombats. When the cattle were brought to Australia in the 1880's by European settlers, the beetles were not used to the texture of the dung. It was much different and the dung was not decomposing. Native beetles were not using this dung as a feeding source. This left the cattle not feeding in the pasture because they won't eat near the dung. This reduced the cattle grazing land.
The density would be 14.567 lb/cu ft
Answer:
The student explains that this path is the result of the orbit around which the Earth rotates. Every planet has an orbit which allows it to rotate around the Sun. The Earth also has a slanting axis around which the Earth rotates so that day and night can be caused. Those areas which are in front of the Sun experience day time and those which are backwards experience night time.
