Answer: Transcription
Explanation:
RNA polymerase is an enzyme that plays a key role in the process of transcription, which is the synthesis of mRNA (messenger RNA) from a DNA template. Therefore, option (A) is correct.
What is transcription?Transcription is the process by which the information contained in DNA is used to synthesize RNA molecules. It is the first step in the process of gene expression, in which the genetic information stored in DNA is used to produce the proteins and other molecules that carry out the functions of the cell.
During transcription, an enzyme called RNA polymerase reads the DNA sequence and synthesizes a complementary RNA molecule, called mRNA, which carries the information from the DNA out of the nucleus and into the cytoplasm, where it can be used to guide the synthesis of a protein.

Answer:
carbon monoxide
Explanation:
sulfuric acid is litterally acid
sodium hydroxide..... common now
Carbon monoxide (c.) is the gas that makes up the majority of air pollutants.
What is carbon mono oxide?
Carbon monoxide (CO) is a colorless, odorless, and tasteless gas that is produced by the incomplete combustion of carbon-containing fuels, such as gasoline, natural gas, coal, and wood. It is a highly toxic gas and can be harmful to both humans and animals.
When inhaled, carbon monoxide enters the bloodstream and binds to hemoglobin, the molecule responsible for carrying oxygen to body tissues. This binding affinity is much stronger than that of oxygen, resulting in reduced oxygen delivery to organs and tissues. As a result, exposure to high levels of carbon monoxide can lead to symptoms such as headache, dizziness, nausea, confusion, and in severe cases, loss of consciousness and death.
Carbon monoxide is a significant air pollutant, often found in areas with heavy traffic, industrial emissions, and improper ventilation. It is important to have proper ventilation systems and to use carbon monoxide detectors to minimize the risk of exposure to this dangerous gas.

Why are saprotrophs so important to a marine food web?
Answer:
They break down dead organisms and recycle nutrients. They directly help to maintain the population sizes of different predators. They primarily eliminate toxins from the water that can harm phytoplankton.
Explanation:
Hope it helps I found it on brainly
Answer:
They break down dead organisms and recycle nutrients.
Explanation:
Saprophytes are the living organisms that feed upon dead organisms such as plants, animals, and their decaying products. They contribute to the food web because they help in clearing up the biological waste from the environment and make the resources after degradation available to the plants as soil nutrients. Therefore, helps in nutrient recycling in an ecosystem.
In order for a dead organisms remains to become fossilized certain conditions must be met. summarize three of these conditions.
The vast majority of deceased organisms vanish without a trace, so fossilization is a rare process.
What are the conditions that favor fossilization:Hardbody parts (bones, teeth, shells) will fossilize; soft body parts will not but may leave traces (e.g. imprints)Remains preserved (protection against scavenging, erosion, and environmental damage)There is a lot of pressure to get the remains mineralized (i.e. turn hard body parts into fossilized rocks)Anoxic (low oxygen) conditions are used to protect against oxygen damage and to prevent saprotroph decomposition.Thus, we can conclude that hardbody parts remain preserved, and high pressure and anoxic conditions are required during fossilized.

Which directional terms best describe the location of the sternum in relation to the vertebral column? in the axial region of the body, inferior to the vertebral column in the appendicular region of the body, anterior to the vertebral column in the appendicular region of the body, superior to the vertebral column in the axial region of the body, anterior to the vertebral column
Answer:
Anterior
Explanation:
In anatomical terminology there are several words to indicate the position or part of the body that is being mentioned in a more specific and precise way, a group of these terms are called directional terms, they focus on the position of a specific part, one of the words in this group is "anterior" it basically means "in front of". The sternum is in front of the vertebral column.
The sternum, also known as the breastbone, is located in the middle of the thoracic (chest) region of the axial body. The correct answer is: In the axial region of the body, anterior to the vertebral column.
The axial region refers to the central part of the body, which includes the head, neck, and trunk. In this case, we are specifically referring to the trunk region where the sternum is located. Anterior means towards the front or the ventral side of the body. In anatomical terms, the front side of the body is considered the anterior side.
Sternum is positioned anteriorly, meaning it is in front of or facing the front of the body. In relation to the vertebral column, which is part of the axial skeleton and runs along the posterior (back) side of the body, the sternum is anterior.
Therefore, the correct answer is: In the axial region of the body, anterior to the vertebral column.

Describe wavelength, amplitude, and frequency in relationship to vision and hearing
Explanation:
Visual and auditory stimuli both occur in the form of waves. Although the two stimuli are very different in terms of composition, wave forms share similar characteristics that are especially important to our visual and auditory perceptions. Waveforms of different types surround us at all times, however we only have receptors which are sensitive to specific types of wavelengths. In this section, we describe the physical properties of the waves as well as the perceptual experiences associated with them.AMPLITUDE AND WAVELENGTH
Two physical characteristics of a wave are amplitude and wavelength (figure below). The amplitude of a wave is the height of a wave as measured from the highest point on the wave (peak or crest) to the lowest point on the wave (trough). Wavelength refers to the length of a wave from one peak to the next.
The amplitude or height of a wave is measured from the peak to the trough. The wavelength is measured from peak to peak.
Wavelength is directly related to the frequency of a given wave form. Frequency refers to the number of waves that pass a given point in a given time period and is often expressed in terms of hertz (Hz), or cycles per second. Longer wavelengths will have lower frequencies, and shorter wavelengths will have higher frequencies
