Answer:

The correct answer is that the activation energy must be reached.

Explanation:

In order to start a chemical reaction, energy is needed. A certain amount of energy is needed in order to get started. This energy is termed as activation energy. A reaction would not take place unless the molecules or atoms of reactants come together. This takes place only when the particles are in motion, and for motion, energy is required.

The reactants have to overcome forces, which push them away from each other, and the bonds present in the reactants are needed to get dissociated, for both these purpose energy is required. Thus, before the beginning of a chemical reaction, the activation energy must be reached.

Answer:

I do that sometimes I take notes in a separate location so is this like for your math homework cuz I am good enough but I don't like it that much but I'm good at it and sources identify things that will the source is like a key a key like you can open and close the door with and you're opening the key with the source so it really really really really and wouldn't be a good thing to take notes wherever you go like if you were writing a book you would want the source and the emotion and everything you wanted to buy

The type of mutation that occurred here is an inversion of three nucleotide bases (Option A).

<h3>What is an inversion?</h3>

An inversion is a type of mutation where linear order of nucleotide in the mutated sequence is inverted.

In this case, we have an inversion that involves the following bases (bold highlighted) AATCGC TAC GCACGTCAG and AATCGC CAT GCACGTCAG.

In conclusion, this mutation is an inversion of the genomic sequence (Option A).

Aliun [14]

The question is incomplete as the background of the case and symptoms of Jarod is not provided, however, the missing data required for the question is as follows:

Jared was investigating a drug cartel and ate a meal with one of the suspects. After the meal, he had trouble breathing and felt weak and dizzy. Jared may have been poisoned. He is being taken to the CIA hospital for treatment. You are a medical toxologist working for the CIA. It is your job to find out what poison was given to Jared and try to save his life. Patient: Jared Sondheim Age: 32 Occupation: CIA Agent Symptoms: Muscle Weakness Shortness of Breath Dizziness. Jared has arrived at the hospital! It is your job to find out what toxin was used to poison Jared. You can then give him the correct antidote to save Jared's life.

Answer:

Poisning by 2-deoxyglucose syops the glycolysis process which leads to cardiovascular and respiratory symptoms. Due to property of inhibiting the enzyme reqquired for glycolysis, glucokinase. So, there is no ATP production takes place.

Arsenic poisoning inhibits the second stae of cellular respiration, the Krebs cycle which leads to pyruvate accumalation. The symptoms associated with arsenic are diarrhea, sking tone, abdomunal pain, and muscle cramps.

Oligomycin is used as an antibiotic to inhibit proton ATPase present in mitochondria membrane which blocks ATP formation. Watery eyes, cough, congestion in chest and nose are sysmptopms of oligomycin poisining.

The symptoms cyanide poisoning are dizziness, short breath, nd muscle weakness which matches with the symptoms of jarod.
