Answer:
vancomycin
Explanation:
β-lactam antibiotics are those antibiotic that that contain a beta-lactam ring (the cyclic amide with the nitrogen atom attached to the β-carbon) in their molecular structures. This class of antibiotics is the most commonly used and it includes penicillin derivatives, cephalosporins, monobactams, and carbapenems. The mechanism of action of β-lactam antibiotics is inhibition of cell wall biosynthesis in the bacteria.
It is practical knowledge in the sense that we know why some parts of the world are inherently risky to live in. Even though volcanic eruptionis, earthquakes and tsunamis are difficult to predict, it makes sense to have building codes and emergency plans that take this into account.
It is science’s response to the beliefs that natural catastrophes (volcanism, earthquakes and tsunamis) are divine punishments for the evil ways of some individuals.
Even if you will never use or apply this knowledge, knowing about the theory of plate tectonics gives you a current scientific perspective on what we know about the natural world.
It is a good example of how scientific theories proceed by trying to fit several observations into a coherent explanation.
Learning about the observations that needed to be made and explained for the theory to win over scientists helps caution you against people who adopt belief systems without questioning the myths told to them, or those who try to profit from ignorance of how nature actually works.
When it is well taught, it should convince you that, like any scientific theory, plate tectonics is a “work in progress”. New discoveries continue to be made, and it takes creative and logical thinking, debate and a quest for more observations in order to determine which ones prove or challenge the current theory and which ones may lead to its refinement.
Answer:
During transcription, only one strand of DNA is usually copied. This is called the template strand, and the RNA molecules produced are single-stranded messenger RNAs (mRNAs). The DNA strand that would correspond to the mRNA is called the coding or sense strand
