The structure of a nerve cell (neuron) consists of the following parts:
1. Cell body (Soma): Contains the nucleus and other organelles.
2. Dendrites: Branch-like structures that receive signals from other neurons.
3. Axon: A long fiber that transmits electrical impulses away from the cell body.
4. Axon terminals: Branches at the end of the axon that transmit the signal to the next neuron.
Functions: The nerve cell transmits electrical signals to communicate with other neurons, muscles, or glands in the body.
Find the unknown frequency if 24 is the median of the following frequency distribution:
\[\begin{array}{|c|c|c|c|c|c|} \hline \text{Class-interval} & 0-10 & 10-20 & 20-30 & 30-40 & 40-50 \\ \hline \text{Frequency} & 5 & 25 & 25 & \text{$p$} & 7 \\ \hline \end{array}\]
