Gases are a unique state of matter because the volume of a gas can be compressed or expanded based on its temperature. Jacque Ch
just olya [345]

Explanation:

Since Charles found that the volume is directly proportional to temperature when the mass and pressure remain constant this means that with increase in temperature, there will be increase in volume.

Mathematically,       V \propto T at constant Pressure

This equation represents the relationship in Charles' law.

Olenka [21]

Answer:

it is located 1000 nucleotides upstream of the gene’s core promoter - true

it is located 1000 nucleotides downstream of the gene’s core promoter- true

it is in the gene’s coding region - False

Explanation:

These enhancers are located 50 or more kilobases from the promoter they controlled upstream from a promoter, downstream from a promoter within an intron, or even downstream from the <u>final exon</u> of a gene which can be thousands of bp away from the gene's core promoter and can also occur thousands of nucleotides away from the gene's core promoter needing the activity of a DNA -bending protein that binds to the enhancer changing the shape of the DNA and allow interactions between the activators and transcription factors.

What is the single most important factor in determining the temperature of a region?
Vladimir79 [104]
<h2>Answer:</h2>

Geographical location is the single most important factor in determining the temperature of a region.

<h3>Explanation:</h3>

The location of an area and its surrounding environment is most important in its temperature determination. As the area located near to the ocean has a low temperature. And areas which are far away from the waters and there is low precipitation which means low rain. It indicates the higher temperature areas.

Elevation of region, height from the sea level also affects the temperature of region.

What type of molecule contains the most energy?
Effectus [21]

Answer:

Lipids

If i were to guess, without any answer choices, I would say that we get out energy from carbohydrates, and we store energy in lipids, so Lipids (being long chains) might have the most energy.

Explanation:

Please tell me if this is wrong, I did not have much to work with without any answer choices, and this was very broad. :)
