For a closed system, you need two things:
1) a conservation of mass within the boundaries of the system
2) the ability to freely exchange energy to & from the "closed" system with a surrounding external system


So, the answer is <u><em>never</em></u>, since your defining the "system" as the water within the bathtub, and an open bathtub is exposed to evaporation, which is not conserving mass within the defined "system".

Write a scientific explanation using the CER format to answer the question:
matrenka [14]

Answer:

Well i know why

Explanation:

Claim: I believe that the corpse flower uses a chemical reaction to emit an odor for reproducing purposes.

Evidence: (credit: national geographic) says, "... a male emits an odor that attract bugs. And after 12 hours the male spray the trapped bugs with pollen  and lets them go. after that the female corpse flower hopefully attracts some of the same bugs that the male attracted and takes the pollen to reproduce." To sum it down the flowers odor is for attracting bugs that  were attracted by the male flower.

Reason: the reason that the evidence supported my claim is  because i answered why the plant gives of an oder and i said for reproducing purposes  and the evidence states the the female flower takes pollen for the bugs given to them by the male flower.

i REALLY hope this helps unlike the other person

Funny thing is i was looking for an answer and all i had to do is copy and paste this one and i ended up answering it my self.
