The cosmological principle makes assumptions that provide scientific guidelines to enable its study.
Pollen contains the male gamete.
The pollen from one plant is transferred to the stigma of another plant of the same species. Stigma is the female part.
Answer: 200metres per second
Explanation:
The wavespeed of a wave is the distance covered by the wave in one second. It is measured in metre per second, and represented by the symbol V.
Recall that Velocity (V) = Frequency F x wavelength λ
V = F λ
In this case, wavelength (λ)= 20 m frequency = 10 Hz.
Hence, V = F λ
= 20 metres x 10 hertz
= 200 metres per second
Thus, the wave travels at a speed of 200 metres per second

Its like active transport because the person is using energy to push the ball up a ramp. Active transport involves using energy
