The Miller-Urey experiment showed that simple molecules could have arisen abiotically. This chemical experiment included conditions similar to those present on the early Earth, and tested the origin of life under those conditions.
Water (H2O), methane (CH4), ammonia (NH3) and hydrogen (H2) were the chemicals used to produce the results of the experiment, the factors needed for simple life to arise. Given similar conditions on other planets, it's possible that life could arise there as well.
The first answer is volcanoes
The second answer is They move because of convection currents in the mantle
The amoxicillin and the ampicillin are known to degrade the cell wall. both of these antibiotics have β- lactam in their structure. The structure of the ampicillin and the amoxicillin is similar having a single difference at the 4th position of benzene ring. The structure of the amoxicillin have an addition OH or hydroxyl group at the 4th position in the benzene ring.
As the structure of ampicillin and amoxicillin is similar, the bacteria having ampicillin resistance can also show amoxicillin resistance.
MODE OF ACTION OF AMOXICILLIN:
The amoxicillin binds with the pencillin binding proteins, present in the bacterial cell wall. The binding of the amoxicillin inhibits the enzyme transpepetidase, which is an important enzyme for the synthesis of the cell wall. it also inhibit murine hydrolases and inhibit the assembling of cell wall.
The amoxicillin effects the cell walls of the bacteria, as the animals cells do not have cell wall, they only have a cell membrane, the increase in the dose would not effect the animal cell.
The external covering of diatoms are made up of, while slime molds have cell walls containing. diatoms are because they make food through photosynthesis, while slime molds are because they eat decaying plant matter
