Which one of the following is not correctly matched
Culex pipiens – Filariasis
Aedes aegypti – Yellow fever
Anopheles culifaciens – Leishmaniasis
Glossina palpalis -Sleeping sickness
The Correct Option is C
Solution and Explanation
<div>The pair that is not correctly matched is (C): Anopheles culifaciens - Leishmaniasis
Anopheles mosquitoes are primarily known for transmitting malaria, not leishmaniasis. Leishmaniasis is typically transmitted by sandfly vectors. So, the correct match for Anopheles mosquitoes is malaria transmission, not leishmaniasis.</div>

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)

Concepts Used:
Soil as Reservoir of Essential Elements
- Soil is firstly formed due to the slow breakdown and weathering of rocks.
- The clay and the humus part structure colloidal particles in the soil. These colloids hold a lot of charges on their surface and also have a large surface area that assists in the interaction with mineral elements.
- It is also the area of decomposition, a huge number of microbes in the soil decompose the organic remains (leftover) of plant parts or dead animals and release the minerals bound in organic matter.
- Soil can sustain a regular supply of minerals due to the activity of decomposers.
- Nitrogen-fixing bacteria are also found in the soil changing or transforming the atmospheric nitrogen into usable forms to be utilized by the plants.
- Mineral nutrients are withdrawn from the soil at a much faster rate than it gets replenished naturally. Hence, often there is a deficiency of core minerals in the soil.
- The deficiency of crucial minerals affects crop production, which is replenished through artificial fertilisers.
- Macro-nutrients like N, P, K, S, etc. and micro-nutrients like Cu, Zn, Fe, Mn, etc. are ingredients of fertilizers and are used in crop fields based on their requirement.
