Evolution.
Explanation:
It might have acquired the ability to cause disease due to evolution. Due to evolution, the harmless bacteria can turn into infectious pathogens that cause diseases. Evolution is the change in the characteristics of a species over several generations due to the process of natural selection. This evolution in the bacteria occurs due to changing of environmental conditions which changes the genetic makeup of that harmless bacteria and turn into infectious pathogen.
Answer:
Category D
Explanation:
In the USA, the Federal Animal Welfare Regulations require that research laboratories report animal use according to the species as well as the number of individuals subject to experimentation procedures. Moreover, animal use for research/teaching purposes is also reported according to the classification by pain and distress categories. Basically, this classification has four categories (B,C, D and E) in increasing order according to the pain level suffered by research animals. Animals within Category D include those subjected to potentially painful or stressful procedures. In consequence, in this category, it is imperative the utilization of proper anesthetics and/or analgesics in order to diminish the pain and suffering of these animals at the lower level possible.
Answer:
The hypothesis that whether the poly (A) tail degrade after certain limit or not certain limit can be detected by critically analyzing the sample containing bulk amount mRNA (messenger ribonucleic acid). If certain parts were found having certain minimum length, then the hypothesis would be correct. This would show that all the mRNAs with short tails have got degraded.
