Rory is trying to identify a tree from one of its leaves. A question on the dichotomous key that he is using asks whether the le

af has 3-5 lobes or more than 5 lobes. Rory cannot tell whether the leaf in his hand has 5 or 6 lobes. What should Rory do to continue identifying the tree?
Look at other leaves from the same tree, and count how many lobes they have.
Skip this question, since one question does not make a difference.
Start over from the beginning of the dichotomous key.
Find a different dichotomous key to use that does not ask this question.

The answer would be:

Look at other leaves from the same tree, and count how many lobes they have.

If you'd like to know why, read on:

A dichotomous key helps identify an organism based on observable traits. One option leads to another question, which would be more specific based on the choice made before it, so skipping it would not be a good option. Even if you start over from the beginning of the dichotomous key, you will end up with the same question because you are examining the same thing.

Looking at the other leaves is the best choice because the other leaves are part of the organism you are observing, so it would be the same thing.

We used the enzyme, taq polymerase, which is derived from the thermus aquaticus bacterium, in our pcr procedure. Why is this enz
Andre45 [30]

The use of a thermophilic DNA polymerase such as Taq polymerase prevents the denaturation of the enzyme during the heating that is important to separate the newly synthesized strand. So using this enzyme simplifies the PCR technique and increases its efficiency.

Taq DNA polymerase is highly efficient, when it reaches the optimum temperature, it becomes fully functional. It also has a half-life of over two hours (at 92°C), high amplification capacity, and it can add upto 150 nucleotides per second.  It is "special" enzyme because it comes from the bacterium Thermus aquaticus, which lives in hot springs. It is therefore thermostable even at high temperatures, while other polymerases (e.g. E. coli) are not.

Pani-rosa [81]

Option C

Humid subtropical climatic zone would these trees be found

<u>Explanation:</u>

The general trees seen in Humid Subtropical areas are largely evergreen trees, shrubs, and ferns. These are no mighty conifer trees similar to pine and spruce. Largest of these evergreens are more refined. The purpose many plants hereabouts are evergreens is because of the large months of warmness and steady rain.

These shrubs have accommodated to the natural climate circumstances. Numerous broad-leaf evergreens such as palm trees and ferns are seen hither.  Douglas-fir-tanoak forest usually termed "mixed evergreen forest". A rich understory of herbs, shrubs, ferns, and fungi is discovered beneath the towering redwood and other conifers
