its reconstructing pieces of information
The independent variable is that in which the result is dependent on. For experiments, this is usually the item being varied. For this case, what is being varied is that one group is given caffeine while the other is not. That makes the amount of caffeine given to be our independent variable.
I believe it’s A but I’m not too sure
Reason; Warm air rises, and when it rises it becomes cooler. ... If the pressure of the surrounding air is reduced, then the rising air parcel will expand. The molecules of air are doing work as they expand. This will affect the parcel's temperature (which is the average kinetic energy of the molecules in the air parcel).
Answer:
Option C
Explanation:
DNA fragments have negative charge and they move towards the positively charged electrode in gel electrophoresis.
There is no difference in the charge carried by the DNA fragments as they all have the equal amount of charge on them.
The difference in speed of large and small molecules of DNA is due to their sizes.
Large DNA molecules do not pass easily through the pores of the gel while the smaller molecules do not face any such hindrance and are easily passed through the gel . Therefore small DNA molecules move faster.
F plasmid has the largest size and hence it will move slowly.
