Te correct answer is that they do not have true roots.

The soil in the tundra is frozen to the surface most of the year and only the surface layer thaws in summer. The depth of the thaw will determine how far the roots of the plants will be able to deepen. That is why there are no trees in the tundra, since their roots cannot develop. Therefore, the mosses find their niche in these areas, since they do not have true roots, but rhizoids whose main function is the fixation to the substrate, and do not need more than a few millimeters deep for it. It is important to clarify that the vegetation in the tundra is of low height, squatted, since not only must they withstand low temperatures, but they must withstand strong blizzards. Mosses and lichens predominate in these areas.

I believe the question is according to the attached image.
The order of the diagram that would show primary succession in an area that had never before been occupied by living organisms is;
C,A, B, D.
Primary succession occurs in lifeless areas; these are regions in which soil is incapable of sustaining life as a result of factors such as lava flow, newly formed sand dunes, or rocks left from a retreating glacier.

What kind of pattern do you notice with the structure of DNA? For example, what pattern do you see with the rails and rungs of t

Licemer1 [7]

<span>The most obvious patter is that A binds with T and C with G, as is the case with DNA.

The beginning of DNA transcription starts with the binding of the enzyme RNA polymerase to the promoter region. Next, RNA moves begins transcribing in the 5' to 3' direction using one strand of DNA as the template strand. This strand of RNA produced is complimentary with the other strand known as the coding strand except that Thymine is replaced by Uracil. To cleave the strand Bacteria can use what is known as Rho-independent termination where the strand makes a hairpin loop that causes stress and breakage. Or Rho-dependent termination where a protein causes an interaction between the template and mRNA and they disassociate. Termination is not really understood in eukaryotic organisms.</span><span>
