Natural selection is basically when organisms with the best traits survive and pass on their good traits to their offspring so that they will adapt easily and survive. Organisms who do not have ‘good traits’ that help them adapt and escape predators will be killed or eaten before they reproduce.
So in the end, natural selection is a form of evolution that allows the ‘fittest’ animals to survive and reproduce, while weeding out the unfit.
Mitochondria and chloroplast have similar DNA, which is not evidence for the endosymbiotic origins of mitochondria and chloroplasts.
According to the endosymbiotic theory, a chloroplast and a mitochondria were the independent prokaryotes. Both can be ingested by a large prokaryote and resist digestion. As a result, they continued as endosymbionts and eventually lost some of their autonomic properties. They divide by binary fission, have their own genetic material, possess 70s ribosomes, and Both include their own transcriptional and translational machinery.
Therefore, considering endosymbiotic origin theory, Both Mitochondria and chloroplast have similar DNA is not a piece of evidence.

<span>Which one of the following statements does not accurately describe vibrations?
</span>A: Forced vibrations, such as those between a tuning fork and a large cabinet surface, result in a much lower sound than was produced by the original vibrating body.
For a introduced species to be invasive species, there needs to be certain characteristics of the species.
<h3><u>Explanation</u>:</h3>
Invasive species are the species that belong to some other place and are introduced to a new place by means of any human interference. But many species are often transferred from one place to another. But not all of them remain there as an invasive species. This is because for being an invasive species, they need to have certain characteristics:
A. They need to have high rate of reproduction.
B. They need to have short dormancy periods.
C. They need to have high generic variability.
D. They need to be polyphagous and gregarious.
E. They need to have high dispersal rate and great adaptability.
F. They need to have phenotypic plasticity.
