Endogenous processes - Under surface of the earth.
Exogenous processes - Above the surface of the earth.
Lithosphere - Is broken into tectonic plates.
Plates - made of thick slabs of rock, compose the crust/ocean crust .
7 major plates - Pacific, North America, South America, Eurasian, Antarctic, indo-Australian
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:
The correct option is D. Genes determine the trait of an organism.
Explanation:
Option D is correct because genes can be described as the hereditary molecules that determine the characteristics of a person.
Option A is false because each gene is made up of different nucleotide sequences.
Option B is false because genes do not occur as the same number of chromosomes. Rather, there are many genes present on a single chromosome.
Option C is false because all genes are not located in a specific location. Each gene has its specific location on the chromosome which is known as its locus.
Option E is false because genes are not units of RNA. Genes are made up of DNA.
An increase in alcohol consumption
Alcohol can boost GABA activity in the brain in one of two ways: either by acting on the presynaptic cell, which increases GABA release, or. It can influence the postsynaptic (i.e., signal-receiving) neuron, promoting the GABAA receptor's activation.
The brain circuits that regulate motivational processes, such as arousal, reward, and stress, are altered by chronic alcohol consumption. These modifications impact systems that use dopamine, opioid peptides, -aminobutyric acid, glutamate, and serotonin as signaling molecules as well as systems that control the brain's stress response. Frequent episodes of intoxication, obsession with alcohol, use of alcohol in spite of negative effects, and a need to seek out and use alcohol are all signs of alcoholism developing.
