Question:medium

Which of the following statements about the immune response are incorrect ? A. Neutrophils possess lobed nucleus.
B. Hormones are key mediators of an immune response.
C. Macrophages can be found in tissues throughout the body.
D. Eosinophils are the first cells to reach a site of infection.
E. The components of complement cascade are present in blood as inactive zymogens.
Choose the correct answer from the options given below :

Show Hint

Remember:
• Neutrophils \(\rightarrow\) First responders in acute infection
• Eosinophils \(\rightarrow\) Allergy and parasite defense
• Complement proteins \(\rightarrow\) Inactive zymogens in blood Key immune mediators: \[ \text{Cytokines and chemokines} \]

In an oligopolistic market, firm i and firm j have constant marginal cost = c for an identical good. They compete to set prices Pi and Pj. The demand for total market demand Q, where if \(P_i > P_j\), the demand for firm i is 0. If \(P_i < P_j\), the demand for firm i is Q. If \(P_₁ = P_j\), then they share the market equally and hence the demand for firm i is \(\frac{Q}{2}\). In equilibrium, the prices of firms i and j are:

If Y = F(L,K) is a linear homogeneous production function, then multiplying all inputs by a constant factor α = 2 results in output increasing by a factor of:

Production Function

In the table below, firm 1 and firm 2 can cooperate to share market profits or compete with each other. The figures in the cells represent the profits in crores of INR. They can either cooperate with each other where they share INR 10 crores equally. Alternatively, they can compete, which lowers the market output to INR 4 crores, which they share equally. If one of the firms competes while the other cooperates, the former obtains INR 10 crore of profit while the other makes zero profit. In equilibrium, firm A and firm B should respectively:

Firm 2	Cooperate	Compete
Firm 1	5, 5	0, 10
Compete	10,0	2, 2
