The answer is Prokaryotes.
Eukaryotic cells are cells that have a nuclear envelope, cytoplasmic organelles, and a cytoskeleton.
Prokaryotic cells are cells lacking a nuclear envelope, cytoplasmic organelles, and a cytoskeleton (primarily bacteria).
Also Eukaryotic cells have a nucleus in which the genetic material is separated from the cytoplasm.
Also Prokaryotic cells are generally smaller and simpler than eukaryotic cells; in addition to the absence of a nucleus, their genomes are less complex and they do not contain cytoplasmic organelles or a cytoskeleton
So the correct answer would be B.
Hope I helped.
Leaves are the only natural item listed.
Pesticides, smog, and disposable products are not natural.
Answer:
A all of the genes found within the ecosystem
Explanation:
Genetic diversity is the amount of variation in the genetic make up of individuals in a population. Genetic diversity is important for the fitness of a population, increased genetic variability allows populations to adapt to changes in the environment or resources. It is also important for continually producing healthy offspring, reducing the chance that recessive, deleterious alleles will be expressed.
