D. The permain. Had the largest mass extinction
Let's call the colour alleles C for dominant purple, and c for recessive white.
We have crossed Cc with Cc. So if we put that in a Punnett square, we'd have a CC, two Cc and a cc. That would give us a 3:1 ratio of purple to white, so you'd expect 15 purple and 5 white flowers. :)
The answer to the question is no, you can’t expect to find
black sand beaches on Kauai, it is because black sand beaches are only found on
islands that are recently have been formed from the black larva that has been
breakdown from the volcanoes that had been erupted and Kauai is not included.
You can only expect to find at this island is white and yellow sand beaches.
Weathering breaks down and loosens the surface minerals of rock. Hence, the broken rocks are transported to another place where it decomposes and forms soil. Therefore weathering is important for soil formation
<span>The correct answer is A, B and D. Biogeochemical cycles are central to the ecology of earth system. They make the essentail elements accessible and available for the organisms, and maintain their levels, so that the ecology is ot disrupted. The elements move through abiotic and biotic factors, in these cycles, and a state of equilibrium is maintained n the ecosystem. The carbon dioxide levels are responsible fr the temperature of the earth. If Carbon cycles would not have existed, then there would have been a disruption in maintaining the global temperature. Biogeochemical cycles basically continuously recycles the essential materials, for sustaining the life-forms.</span>
