The three structure a flowering plant can use to reproduce asexually are Roots (turbos, rhizomes etc.), stems and leaves. Flowers are used for sexual reproduction, the other parts have the potential to give rise to new plants (or plantlets) adventitiously.

What are bio-fuels considered carbon neutral?
uranmaximum [27]
“The U.S. government considers biodiesel to be carbon-neutral because the plants that are the sources of the feedstocks for making biodiesel, such as soybeans and palm oil trees, absorb carbon dioxide (CO2) as they grow. The absorption of CO2 by these plants offsets the CO2 that forms while making and burning biodiesel.”

What happens during the initiation step of DNA transcription? A ribosome attaches to the initiation codon of a completed mRNA st
Amanda [17]

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:

  • <u>Initiation</u>

It is the process in  which a portion of DNA unwinds and RNA polymerase binds to the promotor region on the DNA.

  • <u>Elongation</u>

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.

  • <u>Termination</u>

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.

what role does fact finding play in the arbitration and mediation process between labor and management
maks197457 [2]

Mediation is the process of two conflicting groups coming together to find a middle term. It is at times the negotiation with the difference and it is normally supervised by a person in authority who oversees and leads the processes.  If the mediation fails them the conflict is placed under arbitration.  The process of arbitration is fully directed by an arbitrator who has same powers as the judge but is limited to the conflict that is being solved. The arbitrator is there to impose a final decision or come up with the resolution to the conflict in the fairest way. He should follow justice after listening to both conflicting side. The arbitrator is not there to find the middle term to be agreed by the two sides.

Destruction of tropical rain forests: helps maintain global temperatures
aliya0001 [1]

Answer:

B. reduces the amount of water vapor

Explanation:

Tropical rainforests is an area of vegetation comprising of predominantly trees. Trees play a major part in sustaining the environment, and hence, the destruction of trees will result in certain negative effects or impacts on the environment.

One of the effects of destroying rainforests according to the options in the question, is the reduction in the amount of water vapor. Trees in rainforests contribute to the addition of water vapor to the atmosphere via transpiration (loss of water through their stomata). Hence, destruction of tropical rain forests will reduce the amount of water vapor.
