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.

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.

Use of steam is the integral part of process in most power plants. In geothermal power plants, thermal energy (heat) from Earth is converted to electricity.
What is geothermal power plants?Geothermal power plants are used to generate electricity using Earth's thermal energy.
The process requires following steps.
Hot water is pumped under high pressure from deep underground through a well.Heating of water and its movement through a turbine creates thermal energy.In next step, it gets converted to electricity. The steam rotates the turbine that activates a generator which helps in producing electricity.Thus, it can be concluded as thermal energy is converted to electricity at geothermal power plants.

describe how glucose formed in a leaf becomes starch stored in a potato tuber
↪Glucose is usually converted into starch for storage. Starch is better for storage than glucose because it is insoluble. Plants like potatoes and other tubers, and also fruits like the banana store starch for later use. This starch is stored by special organelles, or cell subunits called amyloplasts.
☆...hope this helps...☆
Answer:
dehydration synthesis
Explanation:
monomers of the sugar glucose combine to form a single molecule of the sugar maltose. One of the glucose molecules loses an H, the other loses an OH group, and a water molecule is released when the water molecule is lost its no longer soluble hence its stored in the tuber as starch
