Answer:
Quorum sensing is triggered to begin when<u> a sufficient number of bacteria are present .</u>
Explanation:
Quorum sensing -
Quorum sensing is the ability to detect and to respond to the cell population density by the process of gene regulation . Quorum sensing bacteria releases some chemical signal molecules called the autoinducers , that increases the concentration as the function of the cell density .
The detection of the minimum threshold concentration of an autoinducer leads to the alteration in the gene expression .
<span>The answer is cysteine. This is a half essential proteinogenic amino acid with the formulation of HO₂CCHCH₂SH. It is prearranged by the codons UGU and UGC. The thiol side chain in cysteine frequently partakes in enzymatic responses, as a nucleophile.</span>
If a cell did not replicate its DNA (during the S-phase) before beginning mitosis, then the two identical daughter cells would only get one chromosome from each pair. This, instead of the normal (diploid) 2 pairs of each chromosome (2×23=46), would lead to two haploid cells with 23 total chromosomes each. They would be unable to function and sustain life, thus would likely die soon after division.

Answer and explanation:
The garden pea had many advantages to be used as a model in inheritance studies. These plants grow very fast, so you can rise several generations in little time. This fundamental if you want to do this kind of studies. The study object needs to have a brief generational time, so they can be selected and their descendants can be raised again. Another advantage was that garden peas can be raised easily. They don't need any special care. Besides, they were common in the market. Mendel could find them and bought them any time that he wants. Also, they presented visible characteristics that could vary from one plant to another. Some pea gardens had violet flowers, while others had white flowers. Some were tall, while others were small. These made possible to select plants with specifics features and to study if they could transmit these features to the next generations.
It could be really difficult to do the same experiment in humans. several years would have to pass to observe new generations, so during the lapse time of the researcher, only a few human’s generations could be studied.
