Answer:
C. Using controlled conditions
Explanation:
I did the quiz and B turned out to be wrong. D just doesn't make sense. Although A can be true in some experiments, it's not always the case.
Well the variation i'd different beak types was due to forced evolution. This was caused because the different finches of the different islands had different food sources. Like one species had a very broad beak for crushing shells of nuts, where as on another island a bird might have a longer beak due digging up grubs and other insects. But if one bird traveled to a different island then it might starve. Because it is not equipped to survive on that island.
Hope that this helps. Its been a few years but I am pretty sure that this is still accurate. Good luck!
Answer:
It revolves around the title character, Milo Murphy, who is a descendant of Edward A. Murphy Jr., the namesake of Murphy's Law, which states that anything that can go wrong will go wrong.
Answer:
The width of the central bright fringe will increase
Explanation:
In a single-slit diffraction pattern, the distance of the nth-minimum from the central maximum on the screen is given by
where
is the wavelength of the wave
D is the distance of the screen from the slit
d is the width of the slit
The width of the central bright fringe is equal to twice the value of y=1 (first minimum), so:
And we see that it is inversely proportional to the width of the slit: therefore, if the width of the slit is reduced, the width of the central brigh fringe will increase.
