Pioneer species include bacteria and lichens that can grow on bare rock and help make soil. Secondary succession occurs in a formerly inhabited area that was disturbed. Soil is already in place, so pioneer species include small plants such as grasses.
Answer:
The most radioactive purified biological molecule will be RNA
Explanation:
RNA (ribonucleic acid) like DNA, is a long, unbranched macromolecule consisting of nucleotides joined by 3' - 5' phosphodiester bond.
In the cultured yeast, RNA is the most radioactive purified biological molecule because RNA is normally single stranded and does not undergo mutation, replication nor transcription.
Hence, it conserves the ultraviolet light absorbed from the radioactive phosphate during the culturing of yeast
Answer:
The correct answer is - True.
Explanation:
Degradative pathways are the pathways that provide energy for the anabolic reactions, these are catabolic reaction. An activator protein is a protein that enhance the transcription by binding to DNA.
A transcriptional activator are bind to the enhancers or promoter proximal elements. These are the the DNA binding proteins that regulates the transcription of the DNA molecule.
Thus, the correct answer is - true.
After reading the description attached to the graph represented on the picture, I would say that the resistance gene was present in the aphid population as a result of changes in the aphids’ local habitat by the insecticide. I consider the second option as a correct one because according to the amount of spreading of insecticide<span> per year there was a possibility that it caused a such a change.

The M phase, as in the mitosis phase. During mitosis, cells divide and create two new cells. These cells are referred to as the daughter cells.
