Answer:
c. macula densa
Explanation:
The cells of the macula densa are sensitive to the concentration of sodium chloride in the distal convoluted tubule. They are a part of the nephron.
The answer to this item is FALSE as binary fission or division of cell by two would only occur to prokaryotes or some single - celled eukaryotes. This is a process to which after replicating the genetic materials, there exist two daughter cells which are almost the same in size.
<h3><u>Answer;</u></h3>
d. before the Neogene era.
<h3><u>Explanation;</u></h3>
- <em><u>The Silurian Period was a third period of the Paleozoic Era that occurred from 443 million to 416 million years ago. This period occurred after the Ordovician Period and was then followed by the Devonian Period.</u></em>
- Silurian period is the period that many biologically significant events took place. There was a widespread radiations of crinoids, continued priliferation and expansion of the brachiopods and also the oldest known fossils of coral reefs.
Generally speaking, there are 2 major forces that cause genetic divergence in the majority of populations and systems.
And those are;
Natural Selection
and
Mutation
Natural selection causes a divergence due to the fact that organisms with " "better", more advantageous traits dependent on their environment, survive and reproduce, while the others have the lesser chance. (This causes traits in the population to change over time.)
Mutilation/Mutations, on the other hand, is a change in the genetic material of an organism-specifically when DNA is copied incorrectly.
This changes a portion of the genetic makeup of an organism, therefore changing the organism, and changing its future generations of offspring (when made...etc)
