Why is DNA fingerprinting more conclusive when proving a person’s innocence rather than their guilt?

Answer:

Because if your DNA fingerprinting is not at the crime scene it means that you have no involvement in the crime, but if your DNA fingerprinting is at the crime scene, it does not necessarily mean that you are responsible for the crime.

Explanation:

Genetic fingerprint is the characteristic of DNA that allows differentiating each individual, related or not, from any sample that contains genetic material.

In addition to the use for paternity identification, the use of genetic fingerprint recognition is also widely used in forensic science. Currently what is a standard procedure, the collection of genetic material from crime scenes has, for over 20 years, been helping investigators to decide whether DNA samples from suspects and those found at the crime scene come from the same individual. However, a genetic fingerprint is more effective at proving someone's innocence than guilt. That's because if your genetic fingerprint is not found at the crime scene it means that you have no involvement in the crime, but if your genetic fingerprint is found at the crime scene, it doesn't mean you were responsible for the crime, but it does mean that you are a suspect.

DNA fingerprinting is far more conclusive because it is solid proof. It has evidence that a certain person was at a certain place at a particular time frame. Although most criminals do get asked to use the polygraph test, testing guilt I guess, measures only their heart rate. Which in a normal view many regular people would be nervous. There has been countless reports where murders can pass a polygraph test, but then be convicted of a crime due to proof of evidence from fingerprints. Humans are emotional beings, some can crack easily while some won't (through interrogation). So that's why it's key investigations use science to back up their crimes rather that try to measure someone's guilt.

A researcher discovers a new prokaryote that lives on the seafloor near hydrothermal vents. This organism reduces CO2 to form C6
expeople1 [14]

Answer:

D. Chemoautotrophs

Explanation:

Autotrophs in plain are organisms that synthesize their own food while hetrotrophs are organisms that do not synthesize their own food.

Chemotrophs (Chemoautotrophs and Chemohetrotrophs) are a group of organisms that obtain their energy through the oxidation of inorganic molecules, These organisms require carbon to survive and reproduce.

Chemoautotrophs are able to produce inorganic molecules by the fixation of CO2 from their immediate environment. The energy required for this process is got from Nitrogen, Magnesium, Sulphur etc.

Chemohetrotrophs are a class of chemotrophs that are unable to synthesize their own food but rather ingest complex molecules like carbohydrates from the environment.

Phototrophs are a group of organisms unlike chemotrophs that depend on the source of light or sunlight for synthesizing its food or organic molecules.

Photoautotrophs are basically photosynthetic plants which are able to carry out photosynthesis ie the conversion of CO2 and H2O to give Glucose and Oxygen in the presence of sunlight.

Photohetrotrophs are a class of organisms that do not synthesize their own food but rely on other organisms or already made organic molecules.

How does chlorine bond with sodium?
timurjin [86]

Both the sodium and the chlorine atoms need to obtain a stable electron configuration, thus, a complete outer shell of eight electrons.


Sodiums electron design is 2,8,1 and chlorines electron setup is 2,8,7. So all together for the two molecules of the two components to get a total external shell of eight electrons, sodium will give one electron to chlorine, and the chlorine particle will acknowledge the gave electron when responded with each other.

This outcomes in the sodium particle having an electron arrangement of 2,8 so is currently total. The chloride particle currently has an electron configuration of 2,8,8.

Since the molecules have moved toward becoming particles to end up stable, the Na+ and the Cl-particles draw in one another because of their contrary charges, which results in an ionic bond.


This is the reason sodium and chlorine cling to each other when responded.

How are fats absorbed into the lymph? how are fats absorbed into the lymph? in the form of glycerol in the form of chylomicrons
katovenus [111]
The correct answer is in the form of chylomicrons.  
<span>
Digested fats are resynthesized into triglycerides inside the epithelial cells, and there they're coated by proteins. Such structures are called chylomicrons (small globules composed of protein and lipid). The chylomicron is water-soluble and that allows it to travel outside of the cell and enter the lymphatic capillaries-lacteals.</span>
