Answer:
In biology, a gene is a basic unit of heredity and a sequence of nucleotides in DNA or RNA that encodes the synthesis of a gene product, either RNA or protein. During gene expression, the DNA is first copied into RNA.
Euchromatin is a lightly packed form of chromatin that is enriched in genes, and is often under active transcription. Euchromatin comprises the most active portion of the genome within the cell nucleus. 92% of the human genome is euchromatic.
The genes present in heterochromatin are usually inactive. The genes present in euchromatin are either already active or will be active during growth. Heterochromatin is transcriptionally-inactive. Euchromatin is transcriptionally. (This one here is the difference)
Answer:
What will happen to the population of mice that it will keep growing at a tremendous rate without a fear of being caught by a predatory. This will increase the population curve of mice but will decrease the population curve of the cat at similar speed.
What else can happen is that cats will no longer be depending on Mice for their food and they will be finding some alternate food host.
What else can happen is the trait of tailless cannot be favored by environment as proposed by Lamarack in his theory of evolution that if organism acquires some favorable trait during his life then it is possible that he will pass this trait to offspring. Though this trait is not naturally induced therefore, there are no chances that tailless mice can born and nature choose it as a favorable trait.
In 1880 August weismenn did experiment of similar nature, he cut off the tails of 20 successive generations of mice abut not a single tailless mouse was born. Therefore, he proved that until nature selects some traits, they are not that easily passed from one generation to another if induced by human.
Conclusion: <em>Therefore, after 50 generation mice will be just like parent mice with tails however they will have good population and less predators.</em>

It's called a tectonic shift.
These plates are always shifting, and they can either grind in opposite directions, pull away from one another, or collide to create a fault-line.
Negative ways humans can spoil the environment is 1.using too much carbon like in cars,power plants, and green house. 2. littering and dumping trash or oil in the waters or land. 3. over fishing or some times over hunting and even poching. positive effect is 1. they have try to clean the waters and land.2. there are patrols to watch people from over fishing or hunting 3. they are trying to reduce the amount of carbon used in the air.
