As Marta wants to explain the water cycle, it is best to do it via video simulation of the cycle. The correct option is C.
<h3>What is water cycle?</h3>
The water cycle depicts the consistent flow of water within the Earth's and atmosphere's ambience.
It is a complicated system with numerous mechanisms. Liquid water evaporates into water vapor, condenses into clouds, and falls back to earth as snow and rain.
Marta's best bet for explaining the water cycle is to use a video simulation of the cycle as video is the best way to understand the process.
Thus, the correct option is C.

Anything that is currently alive is an organism. Please give more details and I can give you the EXACT option!
If it is a cell type, animal, plant, etc, then it is an organism.
I really hope I helped. Thanks!
Answer:
Option (4).
Explanation:
Lac operon is present in E.coli that regulate the metabolism of lactose in the bacteria. Lac Operon consists of three genes : Lac Y, lac Z and lac A, an operator and a promoter.
I+ P+ Oc Z− Y+ / I− P+ O+ Z+ Y− , in this case inducer is present, promoter is present, constitutive region and the gene lac Z and lac Y indicates the Z and Y. The permease enzyme will made in the presence and absence of lactose due to the presence of I+ P+ Oc in the cell but beta galactosidase is only made in presence of lactose as Y− gene is present in the diploid cell.
Thus, the correct answer is option 4.
Only a fraction of the genes in a cell are expressed at any one time. The variety of gene expression profiles characteristic of different cell types arise because these cells have distinct sets of transcription regulators
