Silver , because electrons in silver metal are more free or we can say can easily conduct electricity as compare to other metals
that is why silver is consider as best conductor

Law state that the potential difference in a circuit is directly proportional to the current.Answered by Ankur Sonowal (Sep 20, 2017 11:58 p.m.)Thanks (1)
-
Given by gear gye Simon ohm
At constant temperature and pressure, the electric current flowing through a conductor is directly proportional to the potential difference across its ends.
V~I As V increases, current also increases and vice versa.
V=IR
where R is resistance , it measure in ohms
which is property of conductor by which it opposes the flow of current through it ,,

Stomata of desert plant are closed during daytime.How do they take CO2?
Posted by Sanya Bhatia (Sep 20, 2017 11:24 p.m.) (Question ID: 44443)
-
Answers:
-
During the day the desert plants absorb water from the roots and keep the stomata closed
so that, the water may not be lost through the process of transpiration.
at night they open up the stomata pores and take in CO2 and the process of photosynthesis is completed by the next day.

Is geotropism due to hydrotropism
Posted by Darshan Kapoor (Sep 20, 2017 10:19 p.m.) (Question ID: 44387)
-
Answers:
-
No their is no similarities in geotropism and hydrotropism because geo means gravity and hydro means water and they show their different processes in plant parts or we can say movement in plant body.Answered by Yogita Sharma (Sep 20, 2017 11:24 p.m.)Thanks (0)
-
No, both are different. Geotropism is the movement of plant towards / away from gravity. Hydrotroposm os the movement of plant towards water.Answered by Payal Yadav (Sep 20, 2017 10:24 p.m.)Thanks (0)
