Answer:

Option C = Ozone

Explanation:

The Percentage of given gases in atmosphere:

Oxygen = O₂ = 20.95 %

Nitrogen = N₂ = 78.08%

Argon = Ar = 0.93%

Ozone = O₃ = 0.000004%

Nitrogen is most abundant gas in atmosphere while oxygen is second most abundant gas. The nitrogen and oxygen are present in diatomic form such as O₂ and N₂.

Water vapors are also present but the percentage vary according to location. In hot humid areas the percentage of water is 0- 4% and it is third abundant gas.

The percentage of other gases in atmosphere are given below:

CO₂ = 0.0360%

Ne = 0.0018%

He = 0.0005%

CH₄ = 0.00017 %

N₂O = 0.0003%

H₂ = 0.00005%

Answer: Option C

Explanation:

Ozone gas is the least abundant gas in the earth's atmosphere.  Their concentration is least but it has hue impact on the people and animals living in earth.

Ozone is the the layer which protects the incoming ultraviolet rays from the sun which reaches the earth.

The percentage of ozone gas is 0.000004% in the atmosphere which is very less.

Read the paragraphs and answer the question that follows.
Artemon [7]
We can infer of the two paragraphs that Geological movements are often hazardous when they happen quickly, and that the movement of plate boundaries does not always cause disaster.

The excerpt is telling us that "the <span>earthquakes caused a lot of damage, as well as dramatic changes to the local ecosystem", which is supporting the conclusion: "geological movements are often hazardous when they happen quickly." 
But is also telling us that "</span>The slip caused several rock formations and structures to develop cracks. However there was no large-scale disaster or disruption.", which is supporting the conclusion:  the movement of plate boundaries does not always cause disaster."

Describe the effect of amanitin on the maximum elongation rate for the wild-type and modified RNA polymerases
Scrat [10]

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
