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.

Would outer space be an ideal spot for a concert? Why or why not? List, write, or draw your response.
zalisa [80]

Answer:

No.

Explanation:

Outer space would not be an ideal spot for a concert for many reasons. One of which, is that there is no sound in space. On Earth, sound travels through air molecules. In outer space there are no air molecules for the sound vibrations to bounce off of.

Equal masses of 3 ideal gases x, y, z are mixed in a sealed rigid container. If the temperature of the system remains constant,
Delvig [45]

Answer:

C)  It depends on the relative molecular masses of X, Y and Z.

Explanation:

Dalton´s law for the partial pressure of an ideal  gas in a mixture is given by the relationship :

Pa =  Xa Ptotal,

where Xa is the mole fraction of gas A times the total pressure  ( Pa + Pb + Pc...)

The mole fraction is, in turn, given by

Xa = mol A / total # moles

Since the moles of a substance  is the mass divided by its molecular weight , it follows that answer C)  is the correct one.

A solution which contains maximum solute at a given temperature is supersaturated.?
Alex Ar [27]
Nah fam, supersaturate is very hard to get.  It actually creates crystals and can only be made through using techniques to improve the solubility of the solution.

This would be false.  It is a saturated solution
