<span>Looking at the two species' DNA would be a good place to start. If there are a number of similarities in their genotypes, then there would be a good chance that the two would also share some type of a common ancestor. This would be evidence that there was some type of selection that took place that necessitated two different species that shared a number of traits and features.</span>
4: a species is a group of interbreeding natural populations that are reproductively isolated from other such groups. Process of Speciation. The process of speciation is a 2 stage process in which reproductive isolating mechanisms arise between groups of populations.
Answer:
Permanent slides ensures preservation of the body parts of the tiny aquatic animals and also also aids good visualization.Most of the exoskeleton of these tiny animals are lost during temporary slides preparation, thus loss of visualization.
Because the animals are transfixed to a point, their body parts can not be moved.
It also saves time, energy and resources spent during observation.
However,because of dehydration during preparation their natural color may be lost which may affect observation of natural features
Explanation:
Answer;
This is because most likely some time a ago there use to be Ammonites living there and as they died there, they got fossilized.
Explanation;
-Fossils of a marine animal called Ammonite are found in large numbers in the Kali Gandaki river in Nepal. Ammonites were sea animals having shells - either straight or coiled. When the Tethys sea disappeared, they were caught in the shale layers of clay and transformed into fossils. This is one of the proofs that the Himalayas were indeed once under water.
The radius of the circle would be 7.42in
