Answer:
I'm sorry but what exactly is your question?
Crossing over, or recombination, is the exchange of chromosome segments between nonsister chromatids in meiosis. Crossing over creates new combinations of genes in the gametes that are not found in either parent, contributing to genetic diversity.

The plant belongs to the group Angiosperm. Vascular plants with seeds could be cycads, Gingko, conifers, or angiosperms. Among those groups, only angiosperms have flowers.
The plant they found have colored, scented flowers which suggests that it could be pollinated by insects or birds. Colored flowers attract birds and insects. Color serves as a guiding mark. Talking of scent, it does not attract bird, but attracts insects. It also serves as the guiding mark.
We use cell membranes to treat disease because the cell membrane is one of the main barriers that pathogens need to overcome, hindering their replication.
<h3>What is the cell membrane?</h3>
The cell membrane is a thin lipoprotein film formed by phospholipids and proteins delimiting the cytoplasm of all types of cells. They prevent invading microorganisms from attaching to the cell and replicating.
Then, using the concepts of cell membrane, we can use them to prevent viral diseases from occurring since the virus cannot fix itself to replicate. So in this case, the cell membrane is one of the main barriers that pathogens need to overcome, hindering their replication.
