How did the Industrial Revolution contribute to the changes in environmental quality that occurred

Biology
1 answer:
melomori [17]3 years ago
7 0

Answer:

Negatively

Explanation:

The Industrial Revolution contributed to the first mass scale pollution of the Earth's spheres by the humans. There was pollution prior to it as well, but it was nothing when compared with the period after it occurred. With the development of the industry, lot of waste was released into the waters, or on the soil, often being very toxic and causing severe contamination. The main energy source was the coal, and the coal that was used was releasing enormous amounts of carbon dioxide and sulfur dioxide into the atmosphere. The places that were located near industrial object, or had industrial objects in them faced enormous pollution of the air, which badly affected the health of the humans, animals, and plants. The first acidic rains caused by the human activity started to appear, causing big damage on the forests.

A young female is unconscious after intentionally ingesting a large amount of aspirin. You will MOST likely find her respiration
Inessa05 [86]

Answer:

Deep and rapid.

Explanation:

Respiration may be defined as the process of exchange of gases between the atmosphere, alveoli and body tissue. Two important process of respiration are inspiration and expiration.

Aspirin drug may also effect the rate of respiration in the individual. The breathing rate get increased after taking the excess dose of aspirin. The increase in the breathing rate results in the rapid and deep breathing of the individual.

Thus, the correct answer is option (b).

What is the determining factor for the transcription of structural genes of the trp operon?
padilas [110]

The right answer is 3. the availability of tryptophan in the environment

The TRP operon regulation depends on the availability of the tryptophan molecule (it depends if the cell need tryptophan or already has it).

There are two modes of regulation of the trp operon: Suppression and Mitigation

*Repression

The synthesis of operon mRNA is controlled by a repressor that blocks transcription when bound by tryptophan, which acts as a co-repressor.

The repressor, a 108 aa homodimer (ie 2 apo-repressor), has helix-turn-helix domains that interact with inverted repeats at the major groove of the operator, thus allowing its fixation.

In the absence of trp, the repressor is inactive and does not attach to the operator. The RNA polymerase can bind to the promoter and transcribe the trp E, D, C, B, A structural genes.

In the presence of trp, the repressor changes conformation and becomes active, so it binds to the operator, preventing RNA polymerase from accessing the promoter so transcription will not occur.

* The Attenuation

This is a premature termination of transcription that is a function of Trp concentration. It takes place at a late moment of transcription while regulation by repression is done during the initiation.

1st Case: Low Trp Rate, Continuous Transcription, → Formation of the Anti-attenuator in the absence of trp, and therefore the synthesis of tryptophan is continued.

2nd case: High rate of trp, stop transcription, → Formation of the attenuator in the presence of trp. This one will attenuate the synthesis of tryptophan.
