The zebra mussel is originally native to the Black and Caspian Seas of Asia. Zebra mussels were first detected in the Hudson Riv
er of New York in 1991. Before the arrival of zebra mussels, the Hudson River supported populations of native unionid mussels. Describe one way an invasive species, such as the zebra mussel, can decrease the carrying capacity for a native species in an ecosystem.
The carrying capacity is the amount of organisms that the habitat is able to support. Invasive species compete with native species for limited resources including food, niche, etc. This phenomenon may have important negative effects on the survival of native species, even it may lead to the extinction if the invasive species is successful
Messenger RNA is transcribed from DNA in the nucleus. DNA contained in chromatin. Messenger RNA then makes its way from pores in the nucleus to the cytoplasm where ribosomes will transcribe it into protein.
Explanation: Some regions of a polypeptide may coil or fold back on themselves. This is called secondary structure, and the coils or folds are held in place by hydrogen bonds.
