The intestinal villi crypts will make a wave area on the intestine wall so it will broaden the surface area of intestine. When the surface area of intestine become broader, intestine will absorb more food.
Answer:
B
Explanation:
The spine of a human is S shaped as opposed to that of a chimpanzee, that is C shaped. In humans, this shape allows for the weight of the chest to rest upon the pelvis. Conversely, the C shaped spine of apes allows for the weight to be forward which is better for four-legged locomotion.
Explanation:
Global warming is causing global mean sea level to rise in two ways. First, glaciers and ice sheets worldwide are melting and adding water to the ocean. Second, the volume of the ocean is expanding as the water warms.
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.
