Based on this diagram label the positive and negative sides of the DNA fingerprint with a + and – sign.
Answers
We can say that the top of the gel, where the DNA samples were applied, is the negative side, while the bottom of the gel is the positive side.
We can arrive at this answer because:
DNA is a negatively charged molecule.For this reason, when DNA is applied in an electrophoresis vat, it must be placed in the negatively charged portion.This is because the electrophoresis vat will allow an electrical discharge to pass through the vat and drag the DNA from the negative side to the positive side.This movement allows the DNA to present a series of fragments of different sizes that will be observed in a fingerprint, such as the one presented in the question above.
In the figure below you can more accurately see the positive and negative sides.

How is real life fingerprinting different from the techniques used on CSI?
Answers
CSI used various techniques for fingerprinting like powder dusting, iodine fuming, silver nitrate soaking, etc to determine the fingerprint of criminals.

https://brainly.com/question/25961570
Real-life fingerprinting differs from CSI techniques. While CSI portrays fingerprint analysis as rapid and foolproof, reality involves a slower and more nuanced process.
Real-life fingerprinting is a more involved process than the quick and ostensibly error-proof fingerprint analysis seen on CSI. CSI frequently depicts fingerprint matching as a straightforward database search that produces instant identification. However, in the actual world, fingerprint analysis is carried out by skilled experts who painstakingly check ridge patterns, minute spots, and other traits to assure precise matches. To avoid mistakes, this procedure can be time-consuming and requires knowledge.
In addition, the way that huge, networked databases are shown in CSI oversimplifies reality. Although modern technology makes fingerprint comparison easier, the vast network of records that are easily available is more fantasy than reality. Real-world law enforcement databases are subject to stringent guidelines and restrictions.

By 12 weeks, the uterus is just ____________ to the level of the ____________ and is about the size and shape of a large grapefruit. As the uterus expands, it impinges on the space occupied by the ____________ .
Answers
Answer: 1. superior 2. pubic symphysis 3. urinary bladder
Explanation:
Given our understanding of the human anatomy, we can confirm that by 12 weeks, the uterus is just superior to the level of the pubic symphysis and is about the size and shape of a large grapefruit. As the uterus expands, it impinges on the space occupied by the bladder.
As the question tells us once the spaces are filled in, the uterus, which holds the fetus during development, expands as the fetus grows in size. This expansion causes it to extend to the spaces superior to the pubic symphysis and the space occupied by the bladder.
The expansion of the uterus into the space occupied by the bladder causes this organ to have very limited space to expand, thus greatly limiting the amount of urine it can hold which causes more frequent trips to the bathroom.
