ribosome
Small non-polar molecules may pass through a a semipermeable membrane but others require a protein channel.

it depends on the protein: some would be damaged, others denaturated while others will work better and some may not care at all.
A substance that carries electricity under certain circumstances but not under others is called a semiconductor.
Some ribosomes can be found floating free in the cytoplasm, while others are bound to the rough endoplasmic reticulum. (The name "rough" actually indicates the presence of ribosomes, against the "smooth" appearance of the smooth endoplasmic reticulum, which lacks ribosomes). There are several types of ribosomes,(rRNA = ribosomal RNA, mRNA = messenger RNA, tRNA = transfer RNA), all of which has its distinct job in the synthesizing process of protein. Information of regarding this process can be found on http://en.wikipedia.org/wiki/Protein_synthesis Ribosomes are considered "non-membranous organelles", as they differ from other organelles which are membrane-bound.
is an small organelle that makes, or synthesizes, protein. Some Ribsosomes are attached to endoplasmic reticulum, while others float in a cell's cytoplasm.

A semipermeable membrane
Small non-polar molecules may pass through a a semipermeable membrane but others require a protein channel.
These proteins are attached to the membrane and their is a great variety of them. There one called the integral protein that crosses all the way through while others are triggered by biochemical reactions.These are also called carrior proteins and protein channels
Because it is an organelle. Others are organelles too
Through endocytosis. They exit through exocytosis.

Phloem
Some children with protein-energy malnutrition recover completely. Others have many health problems throughout life, including mental retardation and the inability to absorb nutrients through the intestinal tract.
Yes, all fruit and vegetables contain differing amounts of protein
Yes, body mass gain supplements are carried by many online stores such as Amazon.com, Walgreens.com and many others. These are generally protein supplements that help build muscle mass.
