Study the following characters of organisms and identify to arrange in sequence:
A: Glycogen and chitin
B: Pigments in cell, mesokaryon
C: Pellicle, cytostome
Step 1: Understanding the classification of organisms
Fungi store food as glycogen and have chitin in their cell walls.
Dinoflagellates have mesokaryotic nuclei and contain photosynthetic pigments.
Euglenoids possess a pellicle and cytostome for movement and ingestion.
Step 2: Arranging them in sequence
The sequence corresponds to Fungi → Dinoflagellates → Euglenoids.
Final Answer:
Fungi, Dinoflagellates, Euglenoids

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:
