D. Watershed - a watershed is the area in which runoff, rivers, and streams run into a larger body of water
Answer:
Evolution and diversity result from the interactions between organisms and their environments and the consequences of these interactions over long periods of time. Organisms continually adapt to their environments, and the diversity of environments that exists promotes a diversity of organisms adapted to them.
Explanation:
Answer:
c) Alternative splicing
Explanation:
Eukaryotic genes have protein-coding sequences called exons and non-protein coding sequences called introns. Introns are removed from the primary transcript after transcription. Some sequences may serve as both introns and exons. These sequences may be removed as introns or may be retained as exons producing mRNA with different combinations of exons from the single primary transcript. The process of called alternative splicing and allows the formation of more than one mRNAs from a single gene.
Therefore, alternative splicing allows one protein-coding sequence to code for more than one type of related proteins. It does not allow to correlate the number of protein-coding genes with the total number of proteins produced by a species.
Saliva
Rabies virus is an infectious virus which causes rabies in
human and animals. Rabies is transmitted mostly through the saliva of infected animals
such as birds and bats. Transmission of the virus through the human saliva is
rare. Signs and symptoms of rabies virus include fever, headache, partial
paralysis, and vomiting.
