<span>phospholipid bilayer, which is two layers of phospholipids back-to-back</span>
Answer:
3) 0.75m/s
Explanation:
The wavelength of a wave is calculated using the formula;
λ = v/f
Where!
λ = wavelength of wave (m)
v = velocity or speed (m/s)
f = frequency of wave (Hz)
According to this question, one end of a rope is vibrated to produce a wave with a wavelength (λ) of 0.25 m and frequency (f) of 3.0 Hz.
Using λ = v/f
v = λ × f
v = 0.25 × 3
v = 0.75m/s.
Sensory neurones send data to the brain.. the processes it and send back information with the help of the motor neurons.
Air would go through the trachea, then the bronchi, the bronchioles, and then the alveoli.
