Agricultural and public health scientists are concerned about the spread of white-nose
syndrome (WNS). WNS is a result of a fungus that can infect cave-dwelling bats. While bats
hibernate during winter months, the fungus covers the bats' face and wings. WNS has a near
100% mortality rate, and 5.7 million bats have died since the discovery of the fungus in 2006.
Many scientists are searching for ways to protect these bats. The relationship between this
fungus and bats can best be defined as-
a. commensal, because the bats provide a surface for the fungus to grow.
b. parasitic, because the fungus obtains nutrients and shelter from the bats.
c. competitive, because both organisms use caves as shelter during the winter.
d. mutualistic, because the relationship involves two distinct species living together.

Consider the motion of the balloon and its air contents in terms of momentum. in step 1 above, the total momentum of the balloon and its contents was zero. recall that momentum = mv. both the balloon and the air inside it had a velocity of zero and therefore the total momentum was zero. now think about what happened when the air escaped from the balloon. a certain mass of air accelerated in one direction. in order to keep the total momentum of the system zero, the balloon itself (which has mass) had to accelerate in the opposite direction. use this scenario to you explain why the soda can rotates when the water squirts out of the escape holes. what was your hypothesis concerning the water-filled can? according to your data, do you think your hypothesis was correct? (be sure to refer to your data when answering this question.) summarize any difficulties or problems you had in performing the experiment that might have affected the results. describe how you might change the procedure to avoid these problems. give at least one more example of newton's third law in everyday life.
