Current sensitivities of two galvanometers \( G_1 \) and \( G_2 \) of resistances 100 Ω and 50 Ω are \( 10^8 \) div/A and \( 0.5 \times 10^5 \) div/A respectively. The galvanometer in which the voltage sensitivity is more is:

Choose the correct statement: 
I. Continuous decline in pollinator activity could mean rising of fruits and seeds production. 
II. Conversion of wild lands for domestic use is the cause of disruption of pollinators. 
III. Submerged macrophytes enrich the dissolved oxygen in water.

The relation between \(\mu\) and \(H\) for a specimen of iron is \(\mu = \left[ \frac{0.4}{H} + 12 \times 10^{-4} \right] \text{Hm}^{-1}\). The value of \(H\) which produces flux density of 1 T will be (\(\mu\) = magnetic permeability, \(H\) = magnetic intensity)

Choose the incorrect statements related to internal organization of plants: 
I. Stomata regulate the process of photosynthesis and gaseous exchange. 
II. In bicollateral vascular bundles, xylem and phloem are situated at the same radius of vascular bundles. 
III. Monocot root has more xylem bundles compared to Dicot root.

Find the correct statements regarding the structure of xylem and phloem: 
I. Xylem parenchyma store starch or fat or Tannins 
II. Xylem parenchyma have highly thickened walls and obliterated central lumens 
III. Companion cells are controlled by nucleus of sieve tubes 
IV. Phloem parenchyma is absent in most of the monocots
