You never can know the exact value of a physical or chemical dimension because several reasons: all the instruments have a certain sensibility (sensibility is the smallest variation of the dimension that the instrument can measure) that cannot be overcame.
Answer:
Explanation:
Sounds are wave. They are made through vibrations that travels or moves in the air.
Example-Bell rings- sounds gotten when a bell is ringed.
Spectogram is a way in which the strength of loudness can be represented with time visually. Example of spectogram
spectrogram(x) - It returns the Fourier transform of the input signal, x.
Spectogram x, window- This uses windows to separate signals into segments.
Spectogram, window, Nover lap - This make us of nover lap between adjoining segments.
Answer:
The correct answer is option C. gibberellin.
Explanation:
Gibberellin is a type of fungal and plant growth hormone. Gibberellin is one of five main groups of plant hormones.
Gibberellin has different functions and roles in plant growth and regulation such as stem elongation, stem germination, fruit ripening, and flowering.
The gibberellin acid class of hormones has been commonly used in the control of flowering in several species by the florist,
Thus, the correct answer is option C.
Answer:
1.Ions
2. Neurotransmitter
Explanation:
The neurons transmit the signals in the form of the electrical form and the chemical form.
The electrical signals are generated in the neurons as a result of the flow of ions or electrically charged species to maintain the equilibrium.
The signal from one neuron to another neuron takes place in the form of the chemical signal that is the chemical stored in the terminal of the axon called neurotransmitters.
Thus, ions and neurotransmitters are correct.
