A. Mutualism. This is because both the larvae and the flower are benefited. The larvae is fed, and the flower is pollinated.
Hope this helps!
B
The answer should be B.....
Density is defined as the ratio of mass to the volume.
Density = (1)
Mass of water = 10 grams
Mass of acetone = 10 grams
Density of water = 1
Density of acetone = 0.7857
Put the value of density of water and its mass in equation (1)
1 =
Volume of water = 10
Put the value of density of acetone and its mass in equation (1)
0.7857 =
Volume of acetone = 12.72
Thus, volume of acetone is more than volume of water because the density of acetone is lower.
