Chemical changes are when a new atomically bond is created or one is broken.
Physical changes are when nothing really changes, but they item changes form.
Melting ice is a physical change. The ice is still water, just not frozen.
Breaking glass is a physical change. The glass isn’t changing, its just in smaller pieces.
Filtering a mixture is a physical change. If you filter sand from water it’s still water and sand, just not together anymore.
 
Burning paper is a chemical change. When you burn the paper it is no longer paper, now it’s ash and carbon dioxide.

What happens when there is a high concentration of positive transcription factors but a low affinity for the positive transcript
Troyanec [42]

When there is a high concentration of positive transcription factors but a low affinity for the positive transcription factor

Transcription factors are proteins that regulate the transcription of genes—that is, their copying into RNA, on the way to making a protein.

Proteins called transcription factors, however, play a particularly central role in regulating transcription. These important proteins help determine which genes are active in each cell of your body.

<h3>How does transcription factors affect gene expression?</h3>

Under the influence of transcription factors, the various cells of the body can function differently though they have the same genome. Transcription factors attach to one or more series sites, which are called transcription element binding sites (TFBSs), binding to specific DNA sequences of the genes they control

List four methods that can be used to separate mixturea and give an example of each method​
Evgesh-ka [11]

Distillation, Filtration, evaporation, and Chromatography

The filtration process is generally used to separate a suspension mixture where small solid particles are suspended in liquid or air.

Distillation uses boiling to separate mixtures of liquid solutions. It takes into account that different substances in the mixture will have different boiling points..

Chromatography is the separation of a mixture by passing it in solution or suspension or as a vapor (as in gas chromatography) through a medium in which the components move at different rates

Evaporation is a technique used to separate out homogenous mixtures where there is one or more dissolved solids. This method drives off the liquid components from the solid components
