List - I | List – II | ||
A. | Predator | i. | Ophrys |
B. | Mutualism | ii. | Pisaster |
C. | Parasitism | iii. | Female wasp and fig |
D. | Sexual deceit | iv. | Plasmodium |
The correct matches are:
Predator - II. Pisaster: Pisaster is a sea star that is a predator of mussels and other organisms.
Mutualism - III. Female wasp and fig trees: The relationship between female wasps and fig trees is an example of mutualism, where both organisms benefit.
Parasite - IV. Plasmodium: Plasmodium is a parasite that causes malaria in humans.
Sexual deception - I. Ophrys: The orchid Ophrys employs sexual deception to attract pollinators.
Therefore, the correct option is (4): A-II, B-III, C-IV, D-I.

Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason R.
Assertion A : The potential (V) at any axial point, at 2 m distance(r) from the centre of the dipole of dipole moment vector
\(\vec{P}\) of magnitude, 4 × 10-6 C m, is ± 9 × 103 V.
(Take \(\frac{1}{4\pi\epsilon_0}=9\times10^9\) SI units)
Reason R : \(V=±\frac{2P}{4\pi \epsilon_0r^2}\), where r is the distance of any axial point, situated at 2 m from the centre of the dipole.
In the light of the above statements, choose the correct answer from the options given below :
The output (Y) of the given logic gate is similar to the output of an/a :
