The right answer is Ribosomes
The ribosome is a complex composed of RNA and ribosomal proteins, associated with a membrane (in the granular endoplasmic reticulum) or free in the cytoplasm. Common to all cells (prokaryotes and eukaryotes), the ribosome (and especially its composition) varies according to the organisms, even if it is always composed of two distinct subunits.
The ribosome is a huge ribonucleoprotein complex that allows the translation of mRNAs into proteins.
The organelle responsible for protein assembly is the ribosome. It exists either freely in the cytoplasm or attached to the rough endoplasmic reticulum, which also plays a role in protein modification. The Golgi apparatus further modifies and packages proteins, while the nuclear envelope regulates flow of substances.
Out of the organelles you listed: ribosomes, the Golgi apparatus, the nuclear envelope and the endoplasmic reticulum, it is the ribosomes that are responsible for protein synthesis. Ribosomes can either be found freely in the cell cytoplasm or attached to the endoplasmic reticulum (ER), forming what is known as the rough endoplasmic reticulum (RER). The ER, specifically the RER, plays a role in further modification of proteins. Meanwhile, the Golgi apparatus is involved in further protein modification and packaging, and the nuclear envelope acts as a barrier between the nucleus and the cytoplasm, controlling the flow of substances in and out of the nucleus.

Answer:
All carbohydrates, including sugar, contain the same three elements: carbon, hydrogen and oxygen. Different arrangements of these elements form single units to make different types of carbohydrates.
Carbon and hydrogen
(B) When antibodies bind to a bacterial cell, it may keep that cell from adhering to host cells.
(C) The specific receptors on T cells that would interact with a specific antigen are the same shape as antibodies that will interact with that antigen.
(D) By binding to antigens, antibodies mark those antigens for destruction by macrophages.
(E) By binding to an invader, antibodies attract proteins that lyse the target membrane.
