3A- Negative feedback occurs when some function of the output of a system, process, or mechanism is fed back in a manner that tends to reduce the fluctuations in the output, whether caused by changes in the input or by other disturbances.
3B- Negative feedback loops are used to maintain homeostasis and achieve the set point within a system. Negative feedback loops are characterized by their ability to either increase or decrease a stimulus, inhibiting the ability of the stimulus to continue as it did prior to sensing of the receptor.

Answer:
The most common type of DNA profiling today for criminal cases and other types of forensic uses is called "STR" (short tandem repeat) analysis.
Explanation:
New technologies are regularly introduced and validated to expand the capabilities of laboratories working to recover DNA results with improved sensitivity and informativeness. Forensic laboratories have embraced automation for sample preparation and data interpretation in order to meet increasing throughput demands. Short tandem repeat (STR) typing continues to be the primary workhorse in forensic DNA analysis although other genetic markers are used for specific applications.
The ultimate effect is that because of the unhealthy eating habits, your artery will have a deposit build-up, which can cause blood flow problems. Those blood flow problems can lead to heart attacks and other serious health issues.
Electrons are the smallest of the three particles that make up atoms. Electrons are found in shells or orbitals that surround the nucleus of an atom. Protons and neutrons are found in the nucleus. They group together in the center of the atom.
Anaerobic respiration<span> in muscles. Glucose is not completely broken down, so much less energy is released than during </span>aerobic respiration<span>. There is a build-up of lactic acid in the muscles during vigorous exercise. The lactic acid needs to be oxidised to carbon dioxide and water later. Hope this helps!</span>
