Approximately 5% of the cytosine residues are methylated in the genome of any given eukaryote. In what way is dna methylation related to genetic regulation?.
DNA methylation is related to genetic regulation because this epigenetic mark can turn on/off certain genes.
What is epigenetics?Epigenetics can be defined as any heritable pattern in gene expression that does not involve different nucleotide sequences.
Epigenetic modifications include DNA methylation and histone modifications (e.g., histone acetylation).
These epigenetic marks are able to turn on or turn off specific genes during differential gene expression.

Answer:
The cell cycle is a repeating sequence of cellular growth and division during the life of an organism.
Explanation:
A cell spends most of its time during the first three phases of the cycle. This is called interphase. A cell will ONLY enter the last two phases when it is about to divide. Once again, the cell cycle is a repeating sequence of cellular growth and division during the life of an organism.

Why are none of the outer planets likely to support life similar to that of Earth ?
Answer:
Because of outer planets' extreme environments, it is improbable that they would contain any life. Outer planets are the farthest from the Sun; as a result, some lack necessary heat to support life, while others are hotter than expected for undetermined reasons.

What is the measurement of gravity
Answer:
Gravity is measured by the acceleration that it gives to freely falling objects. At Earth's surface the acceleration of gravity is about 9.8 metres (32 feet) per second per second. Thus, for every second an object is in free fall, its speed increases by about 9.8 metres per second.

At a crime scene you find a piece of glass with a red, dried liquid, and a yellow fiber on the edge lying on the ground. Upon closer inspection, you notice
that there is also a smudged fingerprint crossing the center of the glass. Your job is to plan and carry out an investigation to analyze this evidence. Explain
how you would collect,
preserve and analyze this evidence. What would you hope to find out from this piece of evidence? Indicate whether the glass, red liquid, fingerprint and yellow fiber are each individual or class evidence. Why?
Answer:
For smaller glass fragments should be placed in a paper packet and then in an envelope. Larger pieces should be wrapped securely in paper or cardboard and then placed in a padded cardboard box to prevent further breakage. For analyzing the glass I would start by comparing the refractive index of the sample to that of the possible source. Examination of samples under a regular microscope or a scanning electron microscope can give detailed information about the sample's physical and chemical characteristics. Since the liquid is already dried all you'd have to do is make sure to package it in paper which works since the glass can go in that. For the fiber I would remove it from the glass and collect it with some trace tape. Then the easiest method to get the fingerprint is called dusting, in which I would use a very fine powder that can stick to the oil in the fingerprint. Once the fingerprint becomes visible, lift it from the surface with clear tape and transfer it to another surface to then take into the laboratory to analyze further.
Glass, the liquid and the fiber would be class evidence while the fingerprint is individual.

How does a successful immigration rate impact the biodiversity of an island?
Answer:
as the number of species present increases, the immigration rate decreases
Explanation:
According to ETIB, the number of species present on an island is determined by a balance between immigration and extinction. Generally, as the number of species present increases, the immigration rate decreases and the extinction rate increases.
A successful immigration rate impact the biodiversity of an island in several ways.
How does a successful immigration rate impact the biodiversity of an island ?By the studies of several scientists, the number of species present on an island is determined by a balance between immigration rate and extinction rate. Generally, as the number of species present increases, the immigration rate increases and the extinction rate decreases. Therefore a successful immigration rate provides the animals and birds to migrate from different parts of the world and settle down in a particular island. Therefore for a greater amount of immigration rate, the biodiversity of the island is maintained in a good order. Therefore for a good immigration rate, the biodiversity of a land is largely increased.
