The water will move out of the fish by osmosis due to existence of concentration gradient .
Answer:
Explanation:
Heterochromatin in terms of accessible of the cell's machinery is termed as the region whereby the nucleosomes are tightly packed toghether such that the cell's transcriptional machinery is unable to access this regions. Examples of regions where this is found is at the centromeres, the telomeres and some other few regions in the chromosomes.
Euchromatin in terms of accessibility is the region wherein the nucleosomes are loosely packed such that the cellular processes machines is able to get access to the DNA.
The cell makes DNA in highly compatible state accessible by understood some epigenetic mechanisms such as modification of the histone tails. An example is acetylation; this allows addition of an acetyl group to specific regions on the tail of particular histones that allows for the unwrapping of the history from the DNA making them accessible. This is carried out by some enzymes known as histone acetyltransferases (HATs). Another example is phosphorylation: this does the same as acetylation.
Answer:
This question is asking to fill in the blank spaces with the correct terms. The correct terms to the four blank spaces are:
1) GEL
2) DYE
3) DNA MARKER
4) LID
Explanation:
This question is describing the Gel electrophoresis technique which is used to separate DNA fragments using electric current. The DNA fragments of different sizes migrate through a GEL which serves as the matrix made from Agarose.
In order to physically see the samples that we put in the gel, we first have to add DYE to each sample of DNA. After loading the samples to be separated, a substance made up of DNA fragments of known sizes referred to as DNA MARKER, which acts as the standard curve in a tube is used.
Before running the gel, it's important to make sure that there is LID covering the gel in the gel rig. This will make sure that the electrical current runs through the gel and the gel stays cool.

If the coyote population decreases, there will be no predator to prey on the prairie dogs which will result in the prairie dog population increasing.
