He can assume about the number of adenines and their position on the sequence will be equal between the sample found at the crime scene and one sample from the suspicious individual.
<h3>What is forensics DNA?</h3>
Forensics DNA refers to the techniques to identify suspicious by comparing DNA profiles with those obtained from the crime scene.
Forensics DNA may result very useful to solve criminal cases by comparing nucleotide sequence between samples.
In conclusion, he can assume about the number of adenines and their will be equal between the sample found at the crime scene and the suspicious individual.

The PWS or the Prader-Willi syndrome refers to a rare genetic disorder in which the chromosome 15 gene are either unexpressed or deleted on the paternal chromosome. The paternal origin of the genetic material, which is influenced in the syndrome is essential as the specific region of chromosome 15 taking part is subject to parent of origin imprinting, signifying that for a number of genes in this region, only one copy of the gene is articulated, while the other is silenced due to imprinting.
This signifies that the majority of the individuals exhibit one functioning and one silenced set of these genes. While the individuals with the syndrome exhibits a non-functioning set and a silenced set. The disease is completely autosomal, therefore, it will not predict the sex of the offspring. Also, imprinting is on maternal copy, therefore, if the affected individual is male, it will pass on the mutated copy only in 50 percent of its gametes, and a non-functioning copy to the remaining 50 percent of the gametes. Thus, all of his offspring will exhibit PWS or will get affected.
In other case, if the affected person is female, it will pass on the mutated copy only in 50 percent of its gametes and a non-functioning copy to the remaining 50 percent of the gametes and offspring will take on the functioning copy from its male parent, therefore, all of her offspring will be normal.
Thus, the given statements will be:
1. Sons of affected males have a 50% chance of showing the syndrome - True
2. Daughters of affected males have a 50% chance of showing the syndrome. - True
3. Sons of affected females have a 50% chance of showing the syndrome. - False
4. Daughters of affected females have a 50% chance of showing the syndrome. - False
Answer:
The higher solute concentration is the hypertonic while the low solute concentration is the hypotonic thus on matching it shall be:
1.hypotonic-low solute concentration
2.hypertonic-higher solute concentration
1) Ecology is the scientific study of the distribution and abundance of organisms, the interaction among organisms, and the interactions between organisms and their abiotic environment. Ecologists try to understand the inner workings of natural ecosystems and the species they contain.
2) Ecosystems have no particular size. An ecosystem can be as large as a desert or a lake or as small as a tree or a puddle. If you have a terrarium, that is an artificial ecosystem. The water, water temperature, plants, animals, air, light and soil all work together.
3) The biotic factors of an ecosystem include all the populations in a habitat, such as all the species of plants, animals, and fungi, as well as all the micro-organisms. Also recall that the nonliving factors are called abiotic factors. Abiotic factors include temperature, water, soil, and air.
4) For aquatic ecosystems, these factors include light levels, water flow rate, temperature, dissolved oxygen, acidity (pH), salinity and depth.

Answer:
Climate change has the effect of determining migration of people.
Explanation:
A hazardous environment eg. changes in rainfall patterns, increase in temperature, sea level rise, cyclone frequency has the effect of people migrating to cooler places whereas a conducive environment has the effect of attracting more people to settle there.
