Answer:
The term that best describes enzymes is catalysts.
Explanation:
Lipids and proteins are substrate molecules which enzymes break down. Enzymes are otherwise known as biological catalysts as they help speed up chemical reactions.
Nucleus. it’s the main part that sorts and tells cells what to do and where to go.
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.
The risks of indoor cooking with biofuels and poor ventilation can be reduced through: better ventilation.
<h3>What is chemical pollution?</h3>
Chemical pollution can be defined as the contamination of an environment or waterway, especially through an emission of poisonous, hazardous, and toxic chemical compounds (substances) by humans and various industries.
According to the Environmental Protection Agency (EPA), chemical pollution is a change to waterways and the atmosphere which are mainly caused as a result of human activity.
In this scenario, we can reasonably infer and logically deduce that the risks of indoor cooking with biofuels and poor ventilation can be reduced through better ventilation in the cooking area, so as to efficiently and effectively diffuse the gases.
