Answer:
The correct answer will be option-B
Explanation:
Chlorhexidine is an antiseptic disinfectant which is used in the hospitals before surgery to sterilize the skin and the surgical instruments.
The chemical is used on the patient and the provider to clean the wounds as it is effective on a number of microbes but ineffective on the spores of the microbes.
The structure of the chlorhexidine contains the two phenolic rings and chlorine element.
Thus, Option-B is the correct answer.
Answer:
Air travel is usually the largest component of the carbon footprint of frequent flyers. A single return flight from London to New York – including the complicated effects on the high atmosphere – contributes to almost a quarter of the average person’s annual emissions. The easiest way to make a big difference is to go by train or not take as many flights.
2 The second most important lifestyle change is to eat less meat, with particular emphasis on meals containing beef and lamb. Cows and sheep emit large quantities of methane, a powerful global warming gas. A vegan diet might make as much as a 20% difference to your overall carbon impact but simply cutting out beef will deliver a significant benefit on its own.
Ok since you don't have any answers to choose from I would say Functions is the right answer. Usually we're supposed to explain why but I'm not sure how to for this question, sorry.
Answer:
all organisms share a common genetic code
Explanation:
Bacteria has been genetically modified to produce human insulin protein via genetic recombination. The gene coding for human protein is inserted in bacterial plasmid and then returned back to the bacteria. This arrangement allows faster and inexpensive way of insulin production.
Human insulin gene can be inserted into bacterial DNA because in the end all the organisms share a common genetic code. Genetic code is used by all organisms for gene expression forming the resultant protein. It is dependent on the information carried by the nucleotide triplets which finally get translated. Genetic code is universal which means the triplets will always code for the same amino acid no matter the organism hence bacteria can be used to produce a human protein if the gene can be made available to it.
