How would you explain the outcome of mendel's experiments with pea plants s?

-Mendel discovered that true breeding of Tall plants (T for dominant) are crossed with true bred short plants (t for recessive).The next generation of plants are known as F1 and are tall plants (T)

-he showed that self-pollinated first generation (F1) plants produce an F2 generation with 75% of tall plants (T) and 25% short (t)

i believe the answer is a or 1

when the displaced particles are perpendicular to the direction the wave travels, is called a transverse wave, whereas in longitudinal wave the displace practices are parallel to the direction of the wave.

in the given image:

first image shows - longitudinal wave

second image shows - transverse wave

third image shows - longitudinal wave

fourth image shows - longitudinal wave
