<u>Answer:</u>
<em>In highly diverged lineages, the substitutions process will occur at sites that have been substituted previously</em>.
<u>Explanation:</u>
Molecular clock uses the mutation rate to reduce the time in prehistory when the life forms are diverged. <em>The molecular clock uses the sequence of amino acids and nucleotide sequence for the DNA.</em>
This clock does not measure any time but the number of mutations, and other changes over certain time. <em>Sometimes its useful property might be limited due to the highly diverged lineages.</em>
Explanation:
d. Viruses is your answer
Answer:
All of the above are true.
Explanation:
The prokaryotic organisms are the unicellular primitive organism which was formed in the primitive time when the conditions on the Earth were harsh.
The prokaryotes developed the metabolism to survive in the extreme conditions and were recognised as the archaebacteria. These bacteria can tolerate extreme condition like hot temperature called thermophilic conditions. These thermophiles can grow at higher temperature conditions than the eukaryotes.
The thermophiles are non-phototrophic organism as they do not utilize the light energy to produce energy as phototrophic organisms does.
Thus, all of the true is correct.
The following are included in the freshwater biome : Rivers, Lakes , and Streams.
Oceans have salt/saline water so they are excluded.
In this experiment, they want to test the effect of each wax, with the question being "which wax protects the floor the most from scratches?" or "with which wax does the floor has the least scratches?"
The independent variable depends only on itself and is not affected by others, in this case, it would be the type of wax (expensive, cheap, none).
The dependent variable is the one that would change with the independent variable, in this case, the number of scratches.
The constants would be things that don't change, in this case, the size of the sections, and the kind of tiles.
