The molecule that is least likely to be a subunit of a macromolecule is the steroids.
<h3>What are macromolecules?</h3>
The term macromolecules refers to those molecules that are large and are composed of smaller subunits that are joined together to form the macromolecule. These subunits are called the monomers of the macromolecule that is under study.
We know that the steroids are already large molecules in themselves thus they can not be joined together to form a bigger molecule.
Hence, the molecule that is least likely to be a subunit of a macromolecule is the steroids.

The risk of introducing a natural enemy to control an invasive species is that: The natural enemy may introduce genetic diversity into the invasive species. Thus, option "D" is correct.
<h3>What is non-native?</h3>
Non-native species are considered to be invasive only when they cause harm.
Some of the features that increase the possibility of a non-native species becoming an invasive species are they reproduce easily, they are habitat generalists, they out-compete other plant species, possess the tendency to produce abundant seeds, and are not influenced by the native diseases and pests.
Thus, option "D" is correct.

Answer:
Crossing over
Explanation:
During prophase I of meiosis, homologous chromosomes pair to form bivalents. The chromatids of bivalents may form intimate contact points called chiasmata. At the chiasmata breakage may occur and exchange of chromatids segments between non sister chromatids may take place. This is crossing over ad results in new gene combinations causing variations.
When we see chiasmata under a microscope, that lets us know that prophase I has occurred. During this phase of meiosis, the nuclear envelope breaks up and disappears, and so does nucleolus. The chromosomes become visible at this point.
