Answer:
It is a true example of natural selection.
Explanation:
The dark colour mice lives in the dark soil of southeastern United States in large number as compared to other colour mice because this colour helps them to hide themselves from their predators in that dark soil while on the other hand, on light beaches of Florida light colour mice lives because this light colour also helps these mice in hiding from their enemy animals which is a true example of natural selection because dark colour mice can't survive in light colour beaches dude easily seen by their enemies and reduces its population by eating them.
Answer:
6, 3, 4, 5, 7, 2, 1
Explanation:
Here, speciation occurs because the original butterfly population gets separated into two populations, each facing a different set of environmental conditions. Initially, there was just a single population of butterflies in the valley and all butterflies were able to mate with each other. A fire destroyed their habitat so they had to migrate to other areas. Some butterflies migrated to eastern side of mountain and some to western side of mountain.
Now there were two butterfly populations and they faced different environment from each other. Over the time, the populations adapted to their local surroundings and started to accumulate changes in their genome. Their gene pools started to separate from each other. Eventually they evolved into two different species. When their old habitat was restored in the valley, they returned once again. However, this time they were not able to interbreed because they were now two different species.
Edmond Locard founded the first police crime laboratory in 1910 in Lyon, France. It is impossible for criminals to flee a crime scene without leaving behind traces of evidence that can be used to identify them, according to Locard's "exchange principle."
- This concept served as the foundation for the forensic sciences, a body of methods for collecting and analyzing physical evidence from crime scenes. The "Sherlock Holmes of France," French criminologist Edmond Locard, who founded forensic science, lived from 13 December 1877 to 4 May 1966. Every encounter leaves a trace, according to his formulation of the fundamental tenet of forensic science.
- In the field of research that examines fingerprints, and dactylography, Locard made significant contributions that are well known.
- Although Edmond Locard passed away in 1966, his exchange principle has had a significant impact on forensic science and is still widely cited today.

In addition to revealing chromosomal abnormalities karyotype gives information about the gender of an individual.
<u>Explanation:</u>
A karyotype is the complete information about the chromosomes of an individual, the size, number and type of chromosomes. Analysis of karyotype of an individual gives information about chromosomal abnormalities and genetic disorders if any, in that individual. It is not the only information karyptype gives.
It also gives an idea about the sex of the individual. The sex chromosome of females is homozygous and that of males is heterozygous. Sex chromosome of a female can not be homozygous or heterozygous. Rather, a female can be heterozygous or homozygous for a given allele.
