Answer:
The model that does the best job of showing osmosis is "Thomas. Student-drawn membrane model within a rectangular box. From left to right there is an upper and lower line spaced moderately apart."
Explanation:
Osmosis: this is a process of which molecules of a solvent pass through a semipermeable membrane from a lower concentrated solution into a more concentrated solution.
<span>All of the answer choices relate a source of pollution with its effect; however, all of them except one is correct. <u>The answer is B.</u>
Option A states that the use of aerosol sprays increases ozone; however, the effect is the opposite. Moreover, the depletion does not result in acid rain. In option C, although fossil fuels do cause air pollution, they do not do so by reducing the water vapor content. Instead, they actually increase water vapor content. Their effect is of increasing the content of carbon dioxide, sulfur dioxide and nitrogen dioxide. Finally, CFCs cause ozone depletion, they do not seep into the ground.</span>
The answer would be B.Monomers contains double bonds.
<u>Answer</u>: Option D. RNA polymerase.
<u>Explanation</u>:
- Transcription is the process which is used to produce RNA from a DNA template.
- The enzyme involved in the process of transcription is <em>RNA</em> <em>polymerase</em> which is responsible for separating the DNA strands and making an RNA which is complementary to the DNA.
- RNA polymerase joins the nucleotides in the newly formed RNA strands by utilizing the energy released from the cleavage of the additional phosphate bonds that are removed by it.
- The RNA polymerase dissociates from the DNA only after the process of transcription is complete.
