Answer: option A - an increase in the height of the sound wave
Explanation:
Loud sounds are carried by waves that have a higher amplitude (height between peak and trough) than quiet sounds. The bigger the amplitude of a sound wave, the louder it sounds to our ears.
So, the perceived increase in the volume of sound is best explained by an increase in the height of the sound wave
Answer:
a line because i cant tell if there's not a line
Answer: The correct answer is -
b. Threshold.
Explanation:
Threshold can be described as minimum voltage of a memrane (of neuron or muscle cell) that is required to reach an excited state of cell during a depolarization) so as to produce an action potential.
Voltage-gated channels are activated at the threshold voltage, .
For example - Threshold level of neuron is - 55mV, which means it fires action potential at this level so that information is transferred to another neuron.
D) DNA,messenger RNA,and Transfer RN
If so the answer is that the cell is eukaryotic because it contains mitochondria
