DNA is the same in every cell in the body. They all read from the same genetic blueprint, whether they are muscle cells, skin cells, or heart cells.
it is Because they use the same set of genes in different ways, and these cells are different. So despite the fact that every one of our cells has the equivalent of 20,000 or so genes, every cell can choose which ones it needs to "turn on" and which ones it needs to keep "turned off. heart cells have unexpected attributes in comparison to skin cells since heart cells express unexpected genes in comparison to skin cells.

Answer and Explanation:
Observation is when you take a look at something really closely like examining the object.
For example:
You watch an interesting bird that you've never seen in you're life and decided to study it's feasters. That's called "Observing'.
When a single celled paramedic is placed in a hypotonic solution, the cell swells and then bursts.
<h3><u>
Explanation:</u></h3>
Hypotonic solutions are the solutions that contain more water than present in a cell. Hence, when an animal cell is placed in a hypotonic solution, the cell will undergo osmosis. Osmosis is the movement of any form of solvent through a plasma membrane to a higher concentration from a lower concentration until the the external concentration matches the inner one.
To put it in simple words, when a single animal cell is places in a solution which has more water than other solutes, the water will invade the cell until it can accumulate the amount that equalizes the inner and external concentration. The cell will begin to swell up until there is no more space and finally, it will burst. For example, when you put water on a cloth that has blood stain on it, the cells will burst and make the stain worse than before.
DNA unwinding begins at the Origin of replication.
Answer: Telomerase is the enzyme responsible for maintenance of the length of telomeres by addition of guanine-rich repetitive sequences. Telomerase activity is exhibited in gametes and stem and tumor cells.
