The challenges that scientists who want to study particular genes face are as follows:
1. There are many genes on a typical chromosome - A chromosome<span> typically contains hundreds to thousands of </span><span>genes.
2. </span>A small fraction of each chromosome encodes genes - <span> Genes only make up a small percentage of the genome; the rest is composed of non-coding sequences.
3. </span>It is difficult to distinguish between genes and non-coding genetic information - discriminating between<span> coding and </span>noncoding<span> regions in a given nonannotated genomic sequence is quite difficult.</span>
A. increased demand for natural resources; need to create environmental laws to protect natural resources for human consumption; need to develop air quality control systems for big business; need to ensure proper disposal of human waste
Answer:
Dolphins use their strong snouts as a powerful weapon to ram sharks, targeting their soft underbellies and gills to cause injuries. Sharks pose less of a threat to larger members of the dolphin family. Indeed, orcas are the top predator in the ocean and small sharks are a target for some populations.
