Hi
Mutations are responsible for increasing the antibiotic resistance of some bacterial strains.
As we know that antibiotics are the drugs that target specific strain or type of bacteria, and kill them. These are designed against specific disease causing gene of that bacteria strain. However, as the genome of bacteria is very small in size, and bacteria undergo hundreds of multiplication events in very small span of time. Therefore, upon replicating, there occur chances of mutations in genetic sequence of bacteria.
When the genetic sequence of bacteria is changed even by one base, the drug wont be able to target and kill that strain of bacteria. And researchers need to design new antibiotic against new strains of bacteria.
Antibiotics resistance has become huge issue across the world as it takes alot of time (years) to design and approve an antibiotic.
Hope it help!
Escherichia coli (E. coli) bacteria normally live in the intestines of people and animals. Most E. coli are harmless and actually are an important part of a healthy human intestinal tract.
Question:
Solution (explanation):
Within an ecosystem, we can find photosynthetic organisms such as plants. The general chemical reaction for photosynthesis is 6 carbon dioxide molecules and 6 water molecules, with the addition of solar energy. This produces 1 glucose molecule and 6 oxygen molecules. Therefore, if one of the reactants of the photosynthetic reaction, namely carbon dioxide, decreases, the amount of glucose (energy storage molecules) will decrease. Remember that energy storage molecules include glucose, starch, and fat.
Answer: we can conclude that the correct answer is:
Decrease in energy storage molecules.
Answer:
Photosynthesis releases oxygen
Explanation:
and oxygen is used for breathing if you didn't know :D
Answer:
A. Global warming is the cause
Explanation:
Our climate is getting warmer due to production of heat wave because the heat wave has high temperature which increases the temperature of the surrounding environment. Researchers found that as global temperatures increase, heat waves will become more frequent and the time between them will become shorter and we know that global temperature increase due to global warming so we can say that global warming is the cause of more heat wave.
