The correct answer is B -Eukaryotes.
“Eukaryotes are the organisms that possess a true nucleus (containing the DNA, which is the genetic material) and the membrane bound subcellular compartments ( also known as cell organelles) such as golgi complex, endoplasmic reticulum, mitochondria.
As per the given information in the question, cells of mushrooms, plants, and animals all have visible nuclei under a microscope.
Thus, it indicates that these organisms are eukaryotes.”
Answer:
Bacteria
Explanation:
Bacterial are prokarotes, that inhabit virtually all habitats..Although some may be pathogenic, ,most bacteria are beneficial. They live in mutual relationship with their living hosts.where they help most in catabolic reactions especially in digestion of food and in nutrient cycle.
They lack membrane bound organelles,they have cell wall made up of peptidoglycan, their nucleus is not bounded with double membrane like Eukaryotes.They vary in shapes, most are spherical in shape, with the shape determined by the cell wall and the cytoskeleton in the cystosol.
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
