Polypeptids
A polypeptide is a linear chain (without ramifications) of aminoacids linked by peptidic-bonds. We speak of a polypeptide when the chain contains between 10 and 100 amino acids. Above 100 amino acids are generally referred to as protein.
Among them, multicyclic peptides, phosphorylated peptides or those incorporating non-peptide bonds or conjugated peptides.
Starch
Starch is a mixture of two homopolymers, amylose and amylopectin
* Amylose, slightly branched with short branches and a molecular weight of between 10,000 and 1,000,000 Dalton (600 to 1000 glucose molecules).
* amylopectin or isoamylose, a branched molecule with long branches every 24 to 30 glucose units via α (1-6) bonds. Its molecular weight can range from 1,000,000 to 100,000,000 Dalton (between 10,000 and 100,000 glucose units).
To summarize the structure of the polypeptides is still linear, but the structure of the starch has ramifications.
Answer:
The answer is C.
Explanation:
The initial proportion of 90% light-brown (sand-like) colored fish to 10% mottled fish is the result of the light-brown fish mixing with their background and thus being preyed less by the birds than the mottled fish which are of course more visible above a light brown sandy bottom. The higher predation results in the removal of more mottled fish and thus a smaller number of these fish in the population. When the gravel is added to the bottom of the lake, this situation reverses. Suddenly the light brown fish are more visible to the birds and we can expect that their numbers will decrease, while the mottled fish will become more numerous as they will be harder to spot and capture by the birds, and will therefore survive more than their pale counterparts.
