That way they can get the average result and they're usually more accurate.
The least reactive element in the third period is argon.
Trenches are geological feature is most common at oceanic-continental convergent boundaries.
Explanation:
Usually, the oceanic plate, because it is denser, becomes subducted underneath the continental plate. The enormous stress of the two colliding plates causes the plates to warp abit downwards along the boundary causing a trench to form that stretches the boundary.
As the oceanic plate gets subducted and ‘dives’ into the mantle, it begins to melt into magma. Usually, due to the enormous stress along the boundary, fissures develop on teh continental plate along teh boundary. The magma rises through these fissures and erupts at the surface. Several mountains form long the boundary forming another signature geological feature of convergent boundary which is volcanic arc mountains.

For #1, the answer is A) Ribosomes.
Ethanol is produced by yeast under anareobic respiration.
When Glucose is converted into 2 Pyruvic acid yeast converts this into 2 Ethanol and 2 Carbon Dioxide.
Or simply.
C6H1206 + yeast -> 2C2H50H + 2CO2
Enzyme is zymase.
Hope this helps :).
