Describe how the structures of proteins differ from the structures of carbohydrates
Masteriza [31]

Answer:

Both are considered macromolecules. I'll explain below

Explanation:

Proteins are like a huge Lego construction. Each individual piece gets pieced together to make a larger "thing" - Death Star, House, etc. Each individual piece is a monomer, and the larger construction is the polymer. The monomers are Amino Acids and they get pieced together to form the polymer that is called a protein. The linkage that they use is an amide bond, and in biology it is usually called a peptide bond.

Carbohydrates can be singular monomers or polymer units. They are made of completely different compounds - usually aldehydes or ketones. And they link together through different chemical linkages (acetal or ketal linkages for polymers,hemiacetal or hemiketal linkages for monomers).

Both can be large, 3D strucutres - proteins are only functional as a large, 3D structure, while carbohydrates can be singular.

Why is the position of the eyes of a macaw makes it difficult to judge distance
OLEGan [10]
The position of the eyes of a Macaw are as follows. Each eye is located on either side of the birds head. This is called Monocular vision, opposed to our eyes which are located in front of our head, adjacent to each other. Mono comes from the Greek root word meaning 'alone'. Making it understandable that, that type of vision is more limited.  The operation of their eyes, view things differently in comparison to that of binocular vision (what we humans have). They have a more broad view but cannot judge distance or depth very well.
Hope this helps! If you have any other questions or would like further explanation just let me know! :)
