I just got the question lol
Hope it helped!
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.
Grassland terrestrial biomes are both dependent upon periodic severe drought and/or fire.
Terrestrial biomes are ecosystems that can be found anywhere on earth that has a similar climate pattern and are not necessarily close to one another. Tropical forests are an illustration of a terrestrial ecosystem. Forests, grasslands, deserts, and tundra are some of the different biome types found in the terrestrial environment. There are eight main terrestrial biomes: temperate grasslands, temperate forests, boreal forests, Arctic tundra, and tropical rainforests, savannas, subtropical deserts, and chaparral.
The grassland biome consists of terrestrial areas where grasses predominate and there aren't many big trees or bushes. Temperate grasslands, tropical grasslands (sometimes called savannas), and steppe grasslands are the three main types of grasslands.

the koala lives in the forest Australia has no forests they all burnt down
Answer:
I.
4) The deoxygenated blood then travels through the veins and enters the right side of the heart.
1) The blood leaves the heart through the aorta.
2) The blood travels throughout the body via the arteries to the capillaries.
3) In the capillaries, the exchange of nutrients and gases occurs. Oxygen is absorbed by the cells while carbon dioxide is released into the blood.
II.
2) Exchange of gases happens as oxygen is received by the blood and carbon dioxide is released.
1) The deoxygenated blood flows from the right side of the heart to go to the lungs.
3) The oxygenated blood then returns to the left side of the heart.
