Hello there,

I believe that your correct answer would be "</span><span>Tertiary consumer".
Hope this helps.

<span>Large changes in allele frequencies can occur in a short time - any changes in frequency, occurring as a result of random chance, would have a proportionally larger effect in a small population. </span>
Answer:
What does GGTCAATGCCATAAG into mRNA mean?
Explanation:
After another enzyme (a DNA helicase) has seperated two orginal strands of DNA, the polymerase moves along the template strand and polymerizes free nucleotides into a new antiparallel strand. ... DNA ligase joins pieces of DNA together, mainly joins Okazaki fragments with the main DNA piece.
The geologist time scale was formed when scientists studied rock layers and index fossils worldwide. With this information, they placed Earth's rocks in order by relative age. Later, radioactive dating helped determine the exact age of the divisons in the geologic time scale.
This scale is organized by the 4.6 billion years of earth's history into sections based on important changes seen in the geologic record. The largest intervals are called eons, with each eon containing many millions of years.
In precambarian time the processes that affect Earth's surface have lessened the erosion on the surface. Earth was being hit by meteorites every second. Now there is water erosion and there wasn't back then. The surface changes have lessened over time.
