Answer:
In biology, students study a variety of life processes and learn how different organisms meet the challenges of living in their environment. Major biological concepts for student focus include homeostasis, energy transfer and use, the relationship between structure and function, and change over time.
Explanation:
nitrogen that cannot be used by organisms
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>
