Answer:
4. Circular Chromosomes
Explanation:
We know that eukaryotic chromosomes consist of double-stranded DNA.
But prokaryotic chromosomes are actually circular, which is very different from eukaryotic.
The variation in color and markings is beneficial to the orchid plants because it helps the flowers pollinate efficiently (Option C). It is an adaptation.
<h3>What is an adaptation?</h3>
An adaptation is an evolutionary trait that allows an organism to take advantage of survival and/or reproduction.
Orchid color can attract pollinators by mimicking flowers of plant species that live in the same area.
It is an adaptation known as mimetism, which allows them to take an evolutionary advantage.

Basement membranes are thin, dense sheets of specialized, self- assembled extracellular matrix that surround most animal tissues. The basement membrane is a fibrous matrix composed primarily of glycoproteins, type IV collagen, and laminin that are secreted by the epithelial cells.
Gregor Mendel crossbred two different pea plants. One of the plants had yellow peas (a dominant trait) and one of the plants had green peas (a recessive trait). The yellow pea plant was heterozygous for its trait meaning its alleles will be Yy. The green plant, because it is recessive, was homozygous for its trait, yy. When these plants were crossbred, two of the offspring resulted in heterozygous for the yellow trait and the other two offspring were homozygous for the green trait.
