Microevolution - Allele frequency changes in a certain population over an amount of generations, it can also be simply described as "an evolutionary change in populations".
Energy and matter characterize both physical and biological systems. These systems are defined both by the types of energy and matter they contain and by how that matter and energy move through and between systems. ... This means that energy and matter can change forms but cannot be created or destroyed.
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
Answer: Behavioral genetics
Explanation: This concept indicates that our genes influence our environment and in return, the environment influences our genes. Behavioural genetics has therefore expressed gene-environment interactions on the behaviour of an individual.
If all the droplets were the same size, the droplet with the smallest charge <span>would fall most slowly through the apparatus. Basically, buoyancy is the same for all droplets but the electrical force would be different for each. The higher the electrical force the greater is the gravitational pull towards that droplet. Therefore, the droplet that has the </span>smallest charge<span> would drop most slowly.</span>
