Answer:
interespecific hybridization
Explanation:
The earth has a closed atmosphere. This means that no water can be added to it. That's why we have the water cycle
The two organisms displayed what is known as co-evolution.
<h3>Co-evolution</h3>
It is the reciprocal changes that take place in organisms of different species based on how they interact with each other.
Since yucca flowers and yucca moth change in response to changes in either one of them, they are said to co-evolve.
Co-evolution is a process that takes place gradually, over a long period of time. Without co-evolving, one of the two interacting organisms suffers and may end up going extinct or find another way to adapt.

Answer:
d. Genes that play a role in the same metabolic pathway are organized into an operon.
Explanation:
In prokaryotic organisms like bacteria, polycistronic mRNAs exist which means that each gene does not have a separate promoter of its own. In fact many genes are under the control of a single promoter. These genes being a part of same metabolic pathway are organized into an operon. For example, lac operon and tryptophan operon. In lac operon, three genes named as β-galactosidase, permease and transacetylase are expressed under a single promoter which is known as lac promoter.
In contrast to this, in eukaryotes the mRNAs are monocistronic i.e. only a single gene is controlled under a single promoter.
