This was Lamarck's idea. Here's an example: Suppose giraffes originally had short necks that they stretched to reach high-up leaves in the trees. This continuous stretching of the neck was passed onto offspring, who as a result had slightly longer necks. This continued for multiple generations until we get today's long-necked giraffe. Lamarck was on to something (that something being evolution by natural selection, which Darwin discovered), but his theory wasn't completely correct since organisms can only pass on genes (segments of DNA that code for a characteristic or function) to their offspring. Since "stretching" would not code into DNA, it wouldn't be passed onto offspring, proving Lamarck's theory incorrect.
Answer:
It is difficult to obtain a final conclusion with this information, but it is possible that the sample doesn't contain living organisms whose genetic material is composed of DNA. Another possible reason for this result is that the DNA extraction protocol used in the experiment is not suitable for this sample.
The correct answer is class.
Taxonomic category (rank) is the level of a group of organisms in a taxonomic hierarchy. The major ranks are domain, kingdom, phylum, class, order, family, genus, and species. Higher rank has more general characteristics of organisms. The lowest rank-species contains most specific descriptions of life forms in it.
The precursor of a mitochondrial matrix protein is found in a mutation in the tom22 signal receptor.
Tom22 and Tom20 function as N-terminal matrix targeting sequences' outer mitochondrial membrane receptor proteins. The buildup of mitochondrial matrix-targeted proteins in the cytosol due to a malfunctioning Tom22 receptor protein may be followed by cytosolic turnover of these proteins.
The N-terminal sequence, which directs the protein to mitochondria and is proteolytically processed upon import3, is produced in approximately 70% of mitochondrial precursor proteins3. To get to the matrix, they must pass via the TIM23 and TOM complexes on the inner and outer membranes, respectively.

Answer:
The correct answer is - increase in frequency.
Explanation:
According to the theory of Darwin, organisms most likely survive and reproduce in an ecosystem that is able to change or adapt to the changes in the ecosystem.
According to the modern evolutionary theory that the genes that are responsible for new changes or traits that help a species to reproduce and survive in a particular environment increase in frequency and the genes do not helps decrease in frequency.
