Why are three-dimensional models useful for understanding the lunar phases?

Juli2301 [7.4K]

New moon, quarter moon, full moon are what we call the lunar phases. These are consequences of the motions of the Sun, Earth and moon. Three dimensional models are useful because the face of the moon that catches the light of the Sun depending on their position at any given time could be depicted well. Circular models would be the best visuals for the lunar phases.

Cytotoxic t-cell subpopulations are specialized to combat _______ pathogens, whereas helper t-cell subpopulations are specialize

Katarina [22]

Cytotoxic t-cell subpopulations are specialized to combat intracellular pathogens, whereas helper t-cell subpopulations are specialized to combat extracellular pathogens.

Cytotoxic t-cell are CD8+ cells. Cytotoxic t-cell uses granzymes to kill intracellular bacteria, that lives in the cytosol such as viruses. They identify the pathogen forgein peptids that are bounded to MHC-I on the cell surface.

cd4+ T helper (Th) cells include Th1, Th2, and Th17 cells. They contribute to aliergic reactions and fighting extracellular parasites.

How proteins are made

Ira Lisetskai [31]

Proteins are an important class of molecules that carry out most of the work inside cells. The building blocks of proteins are smaller organic molecules called amino acids. Most organisms, including humans, use only 20 different amino acids to assemble the vast multitude of proteins needed to build and run a cell.

To build proteins, cells use a complex assembly of molecules called a ribosome. The ribosome assembles amino acids into the proper order and links them together via peptide bonds. This process, known as translation, creates a long string of amino acids called a polypeptide chain.

After the polypeptide chain is synthesized, it will sometimes undergo additional processing. For example, some proteins will have certain amino acids removed. Or extra molecules such as sugars or phosphates may be attached to some of the amino acids in a protein.
