Evolutionary theory predicted that bacterial resistance would happen. Given time, heredity and variation, any living organisms including the bacteria will evolve when a selective pressure, in this case an antibiotic is introduced. However it also gives doctors an patient some specific strategies for delaying even more widespread evolution of antibiotic resistance; these strategies include; avoid mild doses of antibiotics over long time periods, don't use antibiotics to treat viral infections, when treating bacterial infection with antibiotics, take all the pills, and also using combination of drugs to treat a bacterial infection.
Answer:
mosquitoes
Explanation:
more population means that they will eat more (decrease in mosquito population)
Ductus Arteriosus is a blood vessel normally present in fetuses during development. The blood vessel is designed to bypass the pulmonary artery and brings blood to the Descending Aorta, as the fetus cannot breath through the lung (being as they are fluid filled). This is normally not a problem because oxygenated blood comes from the mother's blood supply.
Patent Ductus Arteriosus, is what happens when that vessel does not close. While not as dangerous as other congenital defects. However, because there is still a bypass, blood that normally need to be oxygenated by going through the pulmonary arteries to the lungs, can be diverted and placed into the blood stream without vital oxygen. This condition may eventually lead to CHF (congestive Heart Failure) and Pulmonary Hypertension if not treated.
The correct answer is proteins.
Proteins have four structures; (1) primary, (2) secondary, (3) tertiary, and (4) quaternary. Primary structures of proteins are formation of peptides and the peptide bonds between amino acids. Secondary structures of proteins involves the amino acid composition leading to hydrophobic interactions forming either alpha helices or beta sheets. Interactions between secondary structures of proteins will make the tertiary structure which is either soluble (globular) or insoluble (fibrous) proteins. Quaternary structures are the combination of two or more tertiary structures and these are called subunits.
