Answer:
True
Explanation:
The transmission electron microscope, is a potential microscope that can make bigger the objects 1 million times. The main use is to analyze metals and other materials, to observe the arrangements of the particles in it. Also some other structures as the viruses can be observed with this microscope.
When the optic microscope can not see some structures like the organelles, then it is used this kind of microscope.
It is used also to observe some organelles, membranes, and other structures.
I think this picture is very helpful

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.
