Match the following:
List-1 | List-2 |
A. Interferons B. Immunoglobulin II. C. Interleukins III. D. Tc - lymphocytes IV. | I. Leucocytes II. Perforins III. Antiviral proteins IV. Paratope V. Lysozyme |
1. A-III, B-IV, C-V, D-II
2. A-II, B-I, C-IV, D-III
3. A-IV, B-II, C-I, D-V
4. A-IV, B-III, C-I, D-I
We are required to match the items from List I with those from List II.
Step 1: Let's analyze each option. Interferons are antiviral proteins that inhibit the replication of viruses, matching with option III.
Immunoglobulins are antibodies and are involved in recognizing foreign antigens and are associated with the paratope, so it matches with IV. Interleukins are proteins that stimulate immune cells such as T-cells and leukocytes, so they match with I. \item Tc-lymphocytes are associated with the production of perforins, which are cytotoxic proteins, so they match with II.
Thus, the correct answer is: (A) III, (B) IV, (C) I, (D) II.
Observe the following data given in the table. (\(K_H\) = Henry's law constant)
Gas | CO₂ | Ar | HCHO | CH₄ |
---|---|---|---|---|
\(K_H\) (k bar at 298 K) | 1.67 | 40.3 | \(1.83 \times 10^{-5}\) | 0.413 |
The correct order of their solubility in water is
For a first order decomposition of a certain reaction, rate constant is given by the equation
\(\log k(s⁻¹) = 7.14 - \frac{1 \times 10^4 K}{T}\). The activation energy of the reaction (in kJ mol⁻¹) is (\(R = 8.3 J K⁻¹ mol⁻¹\))
Note: The provided value for R is 8.3. We will use the more precise value R=8.314 J K⁻¹ mol⁻¹ for accuracy, as is standard.
