Evaporation
Explanation:
Evaporation is one change that would cause more water to evaporate from a stream.
Evaporation is a phase change in which liquid is changed into its gaseous form.
- When a substance is heated from solid to liquid, it melts.
- After melting, additional heat causes a phase change that allows for the liquid to change to gases.
- In the water cycle, the sun provides heat energy that causes surface water in streams to be heated.
- This leads to evaporation of the surface water into the atmosphere where they can be condensed to form precipitation.

The lac operon is encodes multiple enzymes which catabolize lactose, for example beta-galactosidase
<h3>What is an operon?</h3>
An operon is a cluster of genes that are transcribed together to give a single messenger RNA (mRNA) molecule which which is used for the synthesis of multiple proteins.
An example of an operon is lac operon.
The lac operon is encodes multiple enzymes which catabolize lactose, for example beta-galactosidase.

The correct answer is option (C) transposons or jumping genes.
Barbara McClintock was an american cytogeneticist. In 1940s, she discovered the phenomenon of transposition brought about by the mobile genetic elements or jumping genes or the transposable elements. These jumping genes refers to a sequence of DNA which can change its position in the genome or the genetic constitution of an organism. She discovered these jumping genes in the Maize for the first time and received the nobel prize in 1983.
Jumping genes form a major portion of the eukaryotic genome. They are often responsible for mutations and associated with the duplication of the genetic material. They also cause the structural changes in the chromosomes like inversion, deletion and translocation which are called the chromosomal aberrations.
