This type of data transmission is characterized by continuous information that may be actively changing and is generally characterized by a sin wave

The answer is an analog transmission. It is a continuous sine wave that varies in phase, amplitude or frequency. Measured in Heartz (Hz). The other is digital transmission that has discrete pulses, rather than continuous, and the pulses represent bits (1s and 0s) which can only be modulated by the voltage or intensity (in optical transmission). Measured in Bits per Second.

idk i’m struggling too

because u need two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei to form isotopes.

so since they all have the same shape? i mean maybe because m& m and reeses are both chocolates
