How would the cycle be different if there were no water on earth?
Luda [366]

Answer:

What I expect would happen: First, there would be no clouds. Lack of clouds would mean there would be no rain and the average temperature of the Earth would increase, resulting in large areas of land becoming desert.

Explanation:

The water cycle is the process where water falls as rain, is transported via rivers and streams to lakes and oceans, evaporates into the sky, condenses into clouds, and falls as rain again. Here's a diagram:

water.usgs.gov

water.usgs.gov

So what would happen if there were no condensation stage?

The condensation stage is the one where water vapour gathers together into clouds (and when the clouds become heavy enough with vapour, release water as rain). So the first answer is that there would be no clouds.

Without clouds, I foresee a few things happening:

From clouds come rain. With no clouds, there would be no rain.

Clouds move moisture from lakes and oceans (where it evaporates up) to mountains and other places inland that spark rainfall. And so vast stretches of land would become desert.

Clouds reflect sunlight and help cool the Earth. With no clouds, the average temperature of the Earth would increase significantly.

And so to summarize what I expect would happen. First, there would be no clouds. Lack of clouds would mean there would be no rain and the average temperature of the Earth would increase, resulting in large areas of land becoming desert.

To determine whether regulation of gene expression by short RNAs was a naturally occurring phenomenon, researchers isolated RNA
frutty [35]

Answer:

C. Because an RNA-seq reaction could tell if the fragments were encoded by the genome.

Explanation:

The combination of single-cell RNA sequencing (RNA-Seq) and bioinformatic tools to assemble and annotate sequence reads is currently the most common methodology used to obtain complete transcriptomes from individual cells. RNA-seq is a Next-Generation Sequencing (NGS) technology that enables the analysis of the entire transcriptome, thereby this method can be used to examine gene, allelic and ncRNA expression. In the last years, RNA-seq has become the gold standard technique for direct analysis of ncRNA expression profiles in biological samples and clinical research.
