Matching cell shapes
Tracheid cells are elongated (I - D).
Nerve cells are branched and long (II - C).
White blood cells have an amoeboid shape (III - B).
Red blood cells are round and biconcave (IV - A).
Final Answer: \[ I - D, II - C, III - B, IV - A \]
If the roots of $\sqrt{\frac{1 - y}{y}} + \sqrt{\frac{y}{1 - y}} = \frac{5}{2}$ are $\alpha$ and $\beta$ ($\beta > \alpha$) and the equation $(\alpha + \beta)x^4 - 25\alpha \beta x^2 + (\gamma + \beta - \alpha) = 0$ has real roots, then a possible value of $y$ is:
