Answer:
they considered valid but a certain idea of acquired characteristics being inherited was rejected
Explanation:
his theory was that if the environment demanded a need or use of a structure in an organism it developed it in response to demand leading to natural use or disuse of structures which he said that these new structures would be passed to their offspring leading to emergence of a new species. scientists accepted that the environment has a role in directing phenotypic changes in an individual taking a body builder for example since his muscles will become huge due to continuous use of the muscles in exercises
but scientists rejected his theory of these acquired characteristics were inherited since phenotypically acquired characteristics that do not affect the genotype of an individual can't be inherited
<h3>Your answer is D.</h3>
The insects are the same species.
<h3>Explanation:</h3>
A species is a group of similar organisms able to reproduce (to exchange genes and interbreed) only within the group. That means that organisms from different species could not exchange genes. Since mentioned insect groups are able to reproduce and produce offspring that could also breed, these groups belong to the same species. If they could not reproduce and produce offspring that could also breed, these groups would belong to the different species.
