Quorum sensing is triggered to begin when ___________.

Biology
1 answer:
Lilit [14]3 years ago
5 0

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 .

gogolik [260]

Answer:

The correct order is dehydration, embed in wax, cut into sections, staining

Explanation:

There are certain proceedings needed to obtain stained sections of vegetable or animal tissues for their microscope observations.

These steps are:

  • Obtention of the material: The tissue is cut to an adequate size.
  • Fixation: When tissues are extracted from the organism, they suffer autolysis and putrefaction, so they need to be fixated in order to keep their cells in the best state possible. Fixation involves preserving the original morphological and molecular characteristics of the tissue. Fixation avoids autolysis, putrefaction, distortion, and retraction of cells and the tissue that could affect its volume or morphology.  
  • Dehydration. Once fixated, the fixator must be eliminated and the tissue is dehydrated by using a gradual series of solutions with alcohol in ascendant concentrations. Dehydration must be gradual to avoid tissue deformation.
  • Inclusion. To obtain thin cuts that can be observed under the optic microscope, the tissues must be included in a consistent, firm substance, that might be either hydrophilic or hydrophobic. A hydrophobic medium is paraffin wax, that provides hardness and plasticity.  
  • Cut. The tissue included in wax must be cut in slides or sections thin enough to allow the diffusion and penetration of light. A microtome is used to perform these cuts. When using paraffine for tissue inclusion, the cuts are about  5 to 20 micrometers of thickness.
  • Stain. Once the cuts are performed, paraffin wax must be eliminated. This can be done by using an organic solvent. Then the tissue must be stained. Hematoxylin and Eosin are the most common dyes. Animal tissues in general do not have any natural color, so they need to be stained to be observed.

Which statement describes potassium-argon dating?
Fiesta28 [93]

Answer: Potassium-40 decays into argon gas over time.

Explanation: Potassium-argon dating is a dating method used to determine the age of sedimentary rocks by comparing the proportion of K-40 to Ar-40 in a sample of rock, and knowing the decay rate of K-40.

Potassium-40 undergoes decay following first order kinetics as given below:

_{19}^{40}\textrm{K}\rightarrow _{18}^{40}\textrm{Ar}+_{0}^1e

The observation from the first question would tend to disprove the idea that evolution is based on b. inheritance of acquired characteristics because according to the experiment  <span>theory of <span>adaptation was taken as a basis.
The answer for the next question is definitely adaptation as at first every live -being should get used to its environment in order to develop and so on.</span></span>
