Well, there are two kinds of organisms: osmoregulators, that can regulate the level of salt and the salinity does not affect them (an example is salmon: for salmon this sentence is true. Generally, for most fish this sentence is true)
However, for some species, such shark - osmoconformers - this is false: they are affected by the salinity. in general I would conclude that This is false: the marine salinity DOES affect the fish (and other organisms) living there.
        
                    
             
        
        
        
Oceanography applies chemistry, geology, meteorology, biology, and other branches of science to the study of the ocean. It is especially important today as climate change, pollution, and other factors are threatening the ocean and its marine life.
        
             
        
        
        
Well, many organisms would die. Plants need light so they would  die out rather quickly. The surrounding area would warm up initially due to the green house effect, but would eventually cool down. 
        
             
        
        
        
No, some animals (at the bottom of the food chain) suffer according to natural selection while other animals who are stronger (likely predators) Will succeed more and have a better chance of survival
        
             
        
        
        
Answer:
option A
Explanation:
The protein specific sequence also known as the primary sequence is determined by the sequence of its amino acids linked together by peptide bonds. The sequences of amino acids determine the proteins that will eventually be synthesized. This proteins becomes functional when correct folding pattern/ native conformation of the protein occurs which determines the shape of the proteins. peptide bonds hold the amino acid sequences together, hydrogen bonds involving components of the peptide bonds allow for the existence of the secondary structure either the alpha helix or the beta pleated sheets and then disulphide bonds and other type of bonds helps in the folding of the protein to become a functional protein.
