Answer:
Potato is not a root whereas the rest of the four items are forms of root.
Potato is a stem.
So, option B is the odd one out
Students were asked to place a mint in their mouths and determine how long it took for the mint to dissolve. The condition of the mint varied in each student group. One group of students were asked to leave a whole mint in their mouth, not moving it around, and let it dissolve. Another group swirled a mint, while the other groups used mints broken into smaller pieces. See the chart for all of the manipulated variable. After reviewing that data table, what kind of result would you predict for the swirled, whole mint?
A) The time is likely between 10-30 seconds.
B) The time is likely between 40-80 seconds.
C) The time is likely between 90-160 seconds.
D) The time is likely between 100-200 seconds.
ANSWER: B) The time is likely between 40-80 seconds.
EXPLANATION:The time is likely between 40-80 seconds.
By swirling the mint, this is agitating and creating a higher frequency of collisions between the saliva particles and mint particles, increasing the rate of dissolution. Therefore, the time is likely to be less than the mint cut in half but probably more than the mint when it is in small pieces.

Answer:
6
Explanation:
Following are the possible transition
1 ) 4 to 3
2) 4 to 2
3) 4 to 1
4 ) 3 to 2
5 ) 3 to 1
6 ) 2 to 1 .
There are altogether 6 wavelengths of photons possible .
This result can be achieved with the help of permutation and combination.
No of ways in which 2 things can be selected out of 4 things , combination being all different.
₂C⁴ = (4 X 3) / 2 = 6.
