Butterflies belong to the phylum Arthropoda.
The heat of fusion of the ice is the amount of energy that is required in order to melt one gram of ice. In this item, in order to solve for the heat of fusion, we simply have to divide the given energy by the mass.
heat of fusion = 16650 J / 50 g = 333 J/g
Thus, the heat of fusion of the ice is 333 J/g.
Answer:
In a research there are two variables independent and dependent variable. independent variable is defined as the variable which is controlled and changed in a scientific experiment and evaluate the effects on the dependent variable while the variable which are tested and measured in experiment are called dependent variable.
When antibiotic is sprayed at one side of the petri dish, the bacterial growth on that side will eventually decrease in comparison to other side.
So, the independent variable in this experiment will be antibiotic because it is used to understand the growth of bacteria by decreasing their numbers and the dependent variable in this experiment will be bacteria as they vary according to the change in independent variable that is antibiotic.
The whale's flipper and tail flukes and fish fins are analogous structure as they have different structural formation but they perform the same function.
Flipper and tails are locomotory organs in the whale and helps the whale in propelling similarly fins in the fish assist the fish in swimming. Both the strcutures have evolved differently and are made of different materials.
