Answer:
respiratory system
Explanation:
The bronchi become smaller the closer they get to the lung tissue and are then considered bronchioles. These passageways then evolve into tiny air sacs called alveoli, which is the site of oxygen and carbon dioxide exchange in the respiratory system.
Answer:
pathogens
Explanation:
Microorganisms that cause disease are collectively called pathogens.
Answer:
The effect of amanitin on the maximum elongation rate for the wild-type and modified RNA polymerases is that it binds to the RNA polymerases, and reduces the process of translocation which is essential for RNA synthesis that is required for RNA polymerases elongation.
Explanation:
Amanitin is a peptide that is cyclic in nature. It is repelled by water thereby making it an hydrophobic peptide.
Amanitin is a toxic peptide that is found in Amanita ( a type of mushroom).
Alpha Amanitin in particular is the one that affects the elongation rate of RNA Polymerases in the body.
When Alpha Amanitin gets into the body system, it travels straight to the liver and due to its very strong affinity for RNA polymerases, it immediately attaches itself to them.
After the attachment, Alpha Amanitin, is disturbs the bridge helix found in RNA polymerase, preventing the hindering and slowing down the proces of translocation from happening.
Once translocation is hindered, RNA is no longer synthesized. Hence, the elongation of RNA polymerases is hindered and this results in severe illness in the body such as liver failure, cytolysis of the liver
1.It is not natural.
2.It can came up with side effects and unbalance some species.
