(WORTH 30 POINTS!!!) Choose the answer that best describes the geologic process that contributes to the formation of fault-block

mountains. A. The Earth's crust is pushed together which tilts layers of rock on their side producing steep scarps. B. The Earth's crust is pulled apart creating deep folds and then pushed together generating steep scarps. C. The Earth's crust stretched from swelling underneath and vertical movement by blocks generates steep scarps. D. The Earth's crust is pushed together which forces up blocks vertically creating steep scarps.

hoa [83]

Answer:

a.) Hydrogen peroxide are highly reactive oxygen compounds used as an antiseptic

b.) Used in treating punctured wounds due to the nature of the wound which helps microorganisms to thrive.

c.) Fizzing associated with hydrogen peroxide use is due to presence of the enzyme catalase.

Explanation:

Hydrogen peroxide is a chemical compound which is made up of two hydrogen atoms and two oxygen atoms. It is powerful oxidizing agent which takes part in biological reactions. This is possible as it can remove electrons from other biological molecules which can damage other cellular components. It is used an an antiseptic to reduce infection because, being a powerful oxidizing agent, it has the ability to react with cell wall of these microorganisms through removal of electrons thereby causing damage to it.

Punctured wounds are narrow in structure which allows obligate anaerobic organisms to thrive because of reduced oxygen flow in the wound. Hydrogen peroxide can effectively eliminate these organisms which are most likely to cause infection in that site because they lack the enzyme called catalase.

Catalase is an enzyme which is present in living cells except obligate anaerobic organisms. It converts hydrogen peroxide into water and oxygen. The fizzing noticed by Jill while cleaning the wound with hydrogen peroxide is due to the catalase in Jill's own cells which converts the hydrogen peroxide to water and oxygen. When oxygen is given off, fizzing reactions are seen at the surface of the wound.

The protein thorain is encoded by the gene thrL, and thorain is a negative regulator of the thrMN operon. Assume there is no oth
KIM [24]

Answer:

The correct answer is option a, that is, the thrM and thrN would be transcribed at high levels in comparison to non-mutant.

Explanation:

Based on the given information, in the existence of thorain the expression of thrM and thrN will be prevented as thorain functions as a negative regulator. In case, if the gene, which codes for thorain, that is, thrL gets mutated, the coding for the functional thorain would get prevented.  

With the encoding of the non-functional thrL protein, there would be an enhancement in the expression of thrN and thrM genes and it will get transcribed at higher levels in comparison to the non-mutant or the wild-type.
