Answer:
Explanation:
Solids-atoms vibrate in place, there is a definite shape/volume; Liquids-atoms slide around, there is a definite volume only; Gases-atoms are spread far apart, with no definite shape/volume. Hope this helps.
The answer is: sustained (or extended) release preparation.
<span>A sustained-release medication is a drug whose release of the active ingredient is controlled over time, that is to say, that it diffuses more slowly and longer in the body.
</span>These medications can be any type of preparation, it could be tablets, capsules, ophthalmic or dermal insert, suppository...
Answer is: wind will blow from the west to the east.
Wind<span>s blow across the </span>Earth<span> from </span>high pressure system<span>s to </span>low pressure system<span>s.
</span>Wind is <span>natural movement of the air. </span>Winds are classified according to their strengt and the direction from which the wind is blowing.
Answer:
<u>A portion of the DNA unwinds and RNA polymerase attaches to the DNA within the transcription bubble.</u>
Explanation:
Transcription is the process in which DNA template is used to synthesize mRNA.
There are three steps of transcription:
It is the process in which a portion of DNA unwinds and RNA polymerase binds to the promotor region on the DNA.
It is the process in which RNA polymerase moves along the DNA template and synthesizes mRNA. During this process, unwinding of double stranded DNA takes place.
As the RNA polymerase moves along the DNA template, it finally reaches a termination signal and then stops synthesizing. It is followed by the detachment of the newly formed mRNA and RNA polymerase from the DNA.
<u>QUESTION:</u>
- <u> A ribosome attaches to the initiation codon of a completed mRNA strand.</u>
This is the incorrect answer choice as this process does not happen in the process of transcription. This event happens<u> in the process of translation in which mRNA is used to synthesize proteins or amino acids. mRNA attaches to ribosome during this process.</u>
- <u>RNA polymerase moves along the template strand of the DNA creating an mRNA strand.</u>
This is the incorrect answer choice as this event takes place in the process of elongation.
- <u>A portion of the DNA unwinds and RNA polymerase attaches to the DNA within the transcription bubble.</u>
This is the<u> correct answer choice as this event takes place in the process of initiation of transcription</u>
- <u>The mRNA detaches from the RNA polymerase as the RNA polymerase leaves the DNA strand.</u>
This is the incorrect answer choice. This event takes place in the event of termination of transcription.
Neurological - by nerves
Endocrinological - by blood and secrets
