Answer:

The probability that the victim not getting hepatitis virus is 0.4547  

Explanation:

We have given that 7 of 48 units of blood is contaminated with virus causing hepatitis.

So probability of getting hepatitis virus is =\frac{7}{48}=0.1458

So probability of not getting hepatitis virus = 1 - 0.1458 = 0.8542

It is given that severely injured accident victim given 5 units of plasma

So probability that the victim not getting hepatitis virus = 0.8542^5=0.4547

So the probability that the victim not getting hepatitis virus is 0.4547

Answer:

When the muscle starts to contract and needs energy, creatine phosphate transfers its phosphate back to ADP to form ATP and creatine. This reaction is catalyzed by the enzyme creatine kinase and occurs very quickly; thus, creatine phosphate-derived ATP powers the first few seconds of muscle contraction.

1. Dr. Lairmore makes the point that veterinarians don't just treat "the animal," but approach treatment from a "one health" per
poizon [28]
Other things veterinarians are looking at is the boundary between animals, people, and the environment. Veterinarians need to work with human doctors to work on food safety, problems connected to cancer, etc. Veterinarians and human doctors can get facts from each other. The problems we face in society means that they have to cooperate with both the animal health side, the human health side, and environment side as well. One way they think of “one health” is evolving viruses. They are looking at this to find a solution by the use of comparative medicine and observing the environment.
