how a silencer works
Silencer (firearms)
The word silencer in reference to gun suppressor remains in widespread use, although it has since fallen out of favor with some, especially among the firearms industry, being replaced with the more literally accurate term sound suppressor or just suppressor, because a "sound suppressor" does not "silence" any weapon, rather it eliminates muzzle flash and reduces the sonic pressure of a firearm discharging.

Ribosomes link amino acids together in the order specified by messenger RNA (mRNA) molecules.
00
Q99
how are ribosomes made
Ribosome
Ribosomes consist of two major subunits—the small ribosomal subunit reads the mRNA, while the large subunit joins amino acids to form a polypeptide chain.
00
Q99
how are ribosomes made

how are ribosomes made
Ribosome
The sequence of DNA encoding for a protein may be copied many times into messenger RNA (mRNA) chains of a similar sequence.
00
Q99
how are ribosomes made
Ribosome
Ribosomes can bind to an mRNA chain and use it as a template for determining the correct sequence of amino acids in a particular protein.
00
Q99
how are ribosomes made
Ribosome
Amino acids are selected, collected and carried to the ribosome by transfer RNA (tRNA molecules), which enter one part of the ribosome and bind to the messenger RNA chain.
00
Q99
how are ribosomes made
Ribosome
The attached amino acids are then linked together by another part of the ribosome.
00
Q99
how are ribosomes made
Ribosome

00
Q99
how are ribosomes made
Ribosome
Each ribosome is divided into two subunits: the smaller subunit binds to the mRNA pattern, while the larger subunit binds to the tRNA and the amino acids.
00
Q99
how are ribosomes made
Ribosome
When a ribosome finishes reading an mRNA molecule, these two subunits split apart.
00
Q99
how are ribosomes made

Ribosome
Ribosomes from bacteria , archaea and eukaryotes (the three domains of life on Earth ) differ in their size, sequence, structure, and the ratio of protein to RNA.
00
Q99
how are ribosomes made
Ribosome
The differences in structure allow some antibiotics to kill bacteria by inhibiting their ribosomes, while leaving human ribosomes unaffected.
00
Q99
how are ribosomes made
Ribosome
In bacteria and archaea, more than one ribosome may move along a single mRNA chain at one time, each "reading" its sequence and producing a corresponding protein molecule.
00
Q99

11
Q100
what happens to the light independent reactions of photosynthesis?

00
Q100
what happens to the light independent reactions of photosynthesis?

They, instead, release sucrose into the phloem from their starch reserves.
00
Q100
what happens to the light independent reactions of photosynthesis?
Calvin cycle
This process happens when light is available independent of the kind of photosynthesis ( C3 carbon fixation , C4 carbon fixation , and Crassulacean Acid Metabolism ); CAM plants store malic acid in their vacuoles every night and release it by day in order to make this process work.
