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.

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.

The portion of the circulatory system governed by the right side of the heart is _pulmonary_ circulation.
There are two types of circulation,
systemic circulationpulmonary circulationWhat is pulmonary circulation?Pulmonary circulation is developes between the heart and the lungs.
The pulmonary arthery leaves the heart from the right ventricle, divides into two ramifications, and carries deoxygenated blood from the heart to the lungs.
Once in the lungs, the blood release carbon dioxide and takes oxygen.
Carbon dioxide is released from the body by exhalation. Blood takes oxygen from small air sacs named alveoli.Finally, oxigenated blood returns to the heart through pulmonary veins.

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.

How can two organisms with a dominant trait for a specific feature produce an organism with a recessive trait for the same feature?
Answer:
because one of the organisms is heterozygous.
Explanation:
When an organism is heterozygous it carries both a dominant and a recessive allele therefore two organisms that are dominant for a specific trait can produce an organism with a recessive trait because one of those two organisms is heterozygous.

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.
