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!
Answer:
4.) Metaphase also I'm just typing so I get the answer but yes it should be mitosis
Answer:
INDEPENDENT VARIABLE: COCONUT JUICE
DEPENDENT VARIABLE: APPEARANCE OF GREEN SLIME
CONTROL GROUP: THE SIDE OF THE SHOWER HE SPRAYED WITH WATER
CONSTANT: SAME TIME OF MEASUREMENT, SAME SHOWER
Explanation:
- Independent variable is the variable that is changed or manipulated by an experimenter. In this experiment, Homer sprays a side of his shower with COCONUT JUICE and the other side with water. This means that the independent variable is the COCONUT JUICE.
- Dependent variable is the variable that responds to the independent variable. It is the variable that is measured by the experimenter. In this experiment, the dependent variable is the APPEARANCE OF GREEN SLIME on the shower.
- Control group is the group in an experiment that does not receive the experimental treatment (coconut juice). This means that the control group of this experiment is the SIDE OF THE SHOWER HE SPRAYED WITH WATER.
- Constants or controlled variable are the variables in an experiment that are kept unchanged throughout the experiment. In this case, the constant is SAME TIME OF MEASUREMENT, SAME SHOWER.
