If you place a strong acid in water it will likely ionize. If you put the same acid in oil it will not. Why the difference?
denpristay [2]

Answer

An acid that breaks down completely and gives off many ions, or protons, is considered to be a strong acid. ex H₂SO₄

If you place strong acid into water it dissociate acid into H⁺ ions

Water is polar solvent(H⁺ and OH⁻), which has partial positive charge on one side and partial negative charge on the other side.

Strong acids readily dissociate in polar solvents to give H+ ions.

Where as Oil is a non polar solvent it has same charge all over so no dissociation of strong acid will take place.

A fictional bacterial operon is responsible for the production of the biosynthetic enzymes needed to make the theoretical amino
Lostsunrise [7]

Answer:

a. The operon is under positive control

a.) Loss of enzyme synthesis results from loss of regulatory R gene product which is regulated in the presence of Tis ophane for transcription. Absence of (Tis), transcription is positively controlled by regulatory Rprotein

b.) The proposed model reveals Tis / B complex prevents Tis enzymes from undergoing transcription through the RB operator by binding to the B region

the role of the R protein is

-decrease affinity of Tis / B complex to B region of RB

-bind to the R region on RB

- change the conformation of B region

- yield decreased affinity of Tis / B complex when R gene is lacking preventing transcription in the process

Effects of the RB mutations is that R protein will not bind to Tis / B complex to reduce transcription

Where is the best place to live to avoid the problems caused by<br> climate change and why?
Helen [10]
In the us- Anchorage, Alaska because the natural environment is far more resilient to a major weather event than a large city setting and can better adapt to changing sea levels or temperatures. With less people and man-made infrastructure, there are fewer things to be maintained in the area, allowing the wilderness to react naturally to changing weather patterns and climate.
outside the us- Denmark because the country has continued to make strides forward, in air quality in particular. On the previous report, 78.8% of the population was exposed to unsafe levels of fine particle air pollution; now, the figure has dropped to 56.9%. Denmark tops the list of countries doing the most to protect the environment, among them having at least half its energy consumption come from renewables by 2030 and to be independent of fossil fuels by 2050.
