Answer: D. Roots
Explanation:
Sophie said that the part in question does not belong to an animal. This therefore invalidates options B and C as only animals would have lungs or legs.
Sophie then says that the part does not grow in the direction of light so that removes stems as the correct option because stems grow towards light in order to allow leaves to carry out photosynthesis.
Roots on the other hand grow towards gravity so they grow away from light which means that the correct answer is roots.
10.9 because of mass= moles/mv it’s just basic chemistry
Answer:
100.52
Explanation:
from the ideal gas equation PV=nRT
for a given container filled with any ideal gas P and V remains constant.So T is also constant.R is as such a constant.
So n i.e no of moles will also be constant.
no of moles of Ar=3.224/40=0.0806
no of moles of unknown gas=0.0806
molecular wt of unknown gas=8.102/0.0806=100.52
