Answer:
<em>Monocot stems have scattered vascular tissue, whereas eudicots stems have vascular tissue arranged in a ring.</em>
Explanation:
Both monocots and eudicots belong to the plant's sub-division known as angiosperms. However, there are four distinguishing features between the two:
- Monocots have single cotyledons or seed leaves while eudicots have two.
- Monocots usually produce needle-like leaves with parallel veination while eudicots produce broad leaves with net veination.
- Root system in monocots is usually a tap root while it is fibrous root in eudicots.
- Floral parts in monocots are usually in multiple of threes while they are in multiples of fours of fives in eudicots
- Vascular bundles in the stems of monocots are usually scattered about while they are arranged in ring-form in eudicots.
<em>Hence, the only true one among the statements is that monocots stems have scattered vascular tissue, whereas eudicots stems have vascular tissue arranged in a ring.</em>
ANSWER FOR QUESTION 3: The answer would be B.) because work or energy, is equal to the work done by a force, like the ball.
ANSWER FOR QUESTION 4: The answer would be D.) because when a ball roles down a hill the work to push that ball can transfer energy between the ball or other objects and cause the change in the total amount of energy used.
ANSWER FOR QUESTION 5: The answer is mechanical, because both physical and constant, kenitic and potential.

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.
