Answer:

Copy number variations (CNVs)

Explanation:

Copy number variations (CNV) are variations in the number of copies of specific nucleotide sequences present in the genome of organisms of the same species (or closely related species). The Human Genome Project showed that the human genome contains many CNVs, which are caused by duplications and deletions (indels) of large regions of repetitive (non-coding) DNA regions. Since CNV are usually localized in non-coding DNA regions, they generally are evolutionary neutral (i.e., prone to diverge among organisms) and therefore don't affect the phenotype of the individual. Single Nucleotide Polymorphisms (SNPs) represent another type of sequence variation that is abundant across the human genome.

What are the cause and effect relationships driven by variations in the flow of energy into and out of Earth's systems?
ValentinkaMS [17]

A balance of this two process must be maintained in order to attain a constant earth temperature.

<h3>Energy flow in the earth</h3>

The earth in itself is a massive ecosystem. Energy flows into the earth and out of it. The only source of energy input to the earth is the sun. Also, energy is lost from the earth via re-radiation of energy in the form of infrared rays.

However, this inflow and out flow of energy affects the temperature of the earth. A balance of this two process must be maintained in order to attain a constant earth temperature.

What is the use of minutiae<br> (this has to do with forensic science &amp; finger prints)
Harlamova29_29 [7]

The use of minutiae in forensic science is to identify the major points in a finger prints.

<h3>What is forensic science?</h3>

Forensic science is the field of science that deals with the extraction of information especially from scene of criminal cases while making use of their physical evidence, such as fingerprints and DNA.

Minutiae points are the major features of a fingerprint image and are used in the matching of fingerprints.

Therefore, the use of minutiae in forensic science is to identify the major points in a finger prints.
