List - I Organisms | List – II Mode of Nutrition | ||
A. | Euglenoid | i. | Parasitic |
B. | Dinoflagellate | ii. | Saprophytic |
C. | Slime mould | iii. | Photosynthetic |
D. | Plasmodium | iv. | Switching between photosynthetic and heterotrophic mode |
The correct matches are:
Euglenoids can switch between photosynthetic (autotrophic) and heterotrophic modes of nutrition. Thus, A-IV.
Dinoflagellates are mostly photosynthetic. Thus, B-III.
Slime moulds are saprophytic (feed on dead organic matter). Thus, C-II.
Plasmodium is parasitic, obtaining nutrients from a host. Thus, D-I.
Therefore, the correct option is (3): A-IV, B-III, C-II, D-I.

A sphere of radius R is cut from a larger solid sphere of radius 2R as shown in the figure. The ratio of the moment of inertia of the smaller sphere to that of the rest part of the sphere about the Y-axis is :
