Answer:
Well, I looked up, "decontamination stories" and "sterilization errors stories." This seems to show with what you want, but I'm not sure. Here are two example articles anyways.
Explanation:
Decontamination After Radiation Exposure: Simpler Than You May Think (npr.org)
Dirty, missing instruments plague DMC surgeries (The Detroit News)
Those are accurate news sources too.
Answer:
because the sodium channels have a refractory period following activation, during which they cannot open again and it ensures that the action potential is propagated in a specific direction along the axon.
Answer:
Mucus
Explanation:
The protein present in the saliva is known as mucin .
When mucin mixes with water , it turns out to be a slippery substance , known as mucus.
The inner linning of the body produces a slippery and a stringy fluid called the muscus .
The importance of mucus is -
Mucus acts as a protective layer , its acts as a moisturizing layer , to keep the organs from drying out.
Human body produces approximately 1 to 1.5 liters per day.
Answer:
Correct answer is c. It is the final electron acceptor in the aerobic respiration.
Explanation:
Oxygen is a substrate of the aerobic respiration, but it is not the only one. Glucose is also a substrate.
Oxygen is used in the cells to be the final electron acceptor, this means that receives the electrons from NADH and FADH2. That is why, when there is no oxygen available for aerobic respiration, the NADH and FADH2 cannot be oxidized and therefore remain in their reduced form. As a consequence, they cannot be re-utilized during different cellular processes that are NAD+ and FAD dependant, such as glycolysis, pyruvate oxidation and cellular respiration. This means that the ATP synthesis stops.
Oxygen itself does not transport any electrones, this are transported by the cytochrome complex in the mitochondrial membrane. But oxygen is key in receiving those electrones, therefore a very important piece of the electron transport across the mitochondria.
