The best answer is the third option namely an enclosed nucleus.
One major difference between these two types of cells is that a prokaryote cell has no distinct nucleus enclosed with a membrane whereas in a eukaryote cell the genetic material, which is DNA, is packaged into chromosomes and found within a distinct nucleus that is enclosed with a membrane
Examples of prokaryotes are bacteria such as staphylococcus species found as commensals on the skin of man and Streptomyces soil bacteria from which the antibiotic streptomycin is derived.
Examples of eukaryotes are an amoeba, which is a unicellular protozoan that lives in water and a hepatocyte which is a liver cell in man.

Answer:
d. introduce native flowering plants the adult butterflies need for nectar, their main food.
Explanation:
Organisms choose the habitat based on the availability of basic requirements such as food, nutrients, space, etc. in the region. The absence of one or more of these factors makes them choose another habitat. Butterflies feed on nectar made by plants in their flowers. To make the butterflies stay in the landscape, flowering plants adapted to local conditions should be planted. The butterflies would feed on the nectar of these plants and would stay in the landscape.
