Antibiotics are of different spectrums of activity depending on the number of pathogens they can kill. They are different reasons for this differences in antibiotic specificity:
I. Antibiotics interrupt processes found in some but not all pathogen cells. For instance, some antibiotics are directed to cell walls that not all bacteria posses.
II. Some pathogens have no metabolic processes to interrupt. The antibiotics that are directed to metabolic reactions of bacteria are not effective in treating viruses because they do not perform this metabolic reactions.
III. Some pathogens have developed genetic resistance to specific antibiotics. Bacteria have a remarkable genetic plasticity having plasmids that can be easily transmitted among them, which give them antibiotic resistance.
Answer:
A. They have different genetic sequences but are found in the same location on a chromosome.
Explanation:
In genetics, alleles are the variant form of a gene. According to Mendel, there are usually two alleles for most genes except for few cases where there are multiple alleles. Each allele of a pair is contributed by each parent during sexual reproduction. For example, in a gene Tt, the alleles are T for tallness and t for shortness.
Alleles of the same gene are related in such a way that they have different genetic sequences but are found in the same location on a chromosome. The different genetic sequences makes them alternative form of each other.
Vomiting is a common symptom of the stomach flu - it starts a few hours after you're exposed to the virus so there isn't a certain amount of times you will vomit but drinking plenty of fresh, clean water will help you keep hydrated! :)
