Explain your understanding of the rise in use of antibiotics. How are antibiotics used in raising livestock? How does this pose a threat to humans? What can we learn about the process of natural selection and evolution from the antibiotic-resistant bacteria? How should this change the use of antibiotics? Your post/article should be a minimum of 500 words in length.Staphylococcus aureus (staph) is a type of bacteria found on people's skin. These bacteria, along with most other types of bacteria, are usually harmless. They can occasionally cause serious infections that can lead to sepsis or death. Methicillin-resistant Staphylococcus aureus (MRSA) is difficult to treat because of resistance to some antibiotics. Use your knowledge of natural selection to explain how selection for methicillin-resistance in Staphylococcus aureus (MRSA) occurs. Focus on explaining the specifics of how this happens by talking about the variation that has to be present, the characteristics of that variation, impacts on fitness and success of the next generation. Your answer will not require any additional research and will only be a short paragraph based on what you think must be going on here based on other examples of natural selection
- While creation and presence of variation is directionless, natural selection is directional as it is in the context of adaptation. CommentHuman adult males generally have deeper voices than do adult females, which is the direct result of higher levels of testosterone causing the enlargement of the larynx. If one excludes the involvement of gender in the situation, then the pattern that is apparent in the fossil record is most similar to one that should be expected from what type of selection? directional selection stabilizing selection asexual selection disruptive/diversifying selectionWord Bank 2: gradual nonrandom natural selection adapted frequent frequency generations natural selection survive reproduce reproduce natural selection Natural Natural selection is the gradual, Selection process by which biological traits become either more or less in a population based on how much the organisms carrying them are able to It is a key part of how OCcurs.

- In the US, many farmers regularly use the herbicide glyphosate to keep their fields free from weeds. Now, however, they are reporting the presence and spread of “superweeds” which are resistant to the said herbicide. Give a brief explanation of this situation using what you learned about natural selection. (Modified from Hoefnagels, 2016)Assume you are studying a population of ocean shrimp that reproduce asexually. You sequence the ocean shrimp and the species that is their closest living relative that reproduces sexually. You find that the asexually reproducing species has a higher number of mutations in the genome. This finding would provide support for which of the following ideas? Linkage disequilibrium Stabilizing selection Disruptive selection Muller's ratchetHow do mutations and selection work together to create antibiotic resistance? Describe how antibiotics act as a selective pressure on a bacterial population and how mutations can lead to bacteria becoming resistant to antibiotics.
