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.
Fish and marine mammals sift out the salt from the water, then they drink it.
Answer:
The three hormones are insulin, glucagon, and GIP and GLP-1.
Explanation:
After the ingestion of carbohydrates, insulin increases in the blood generating peaks in blood glucose, therefore the hormone that will increase is insulin to lower blood glucose, promoting the entry of this monosaccharide into the cells.
Different from the moments when the person enters into physical activity, and blood glucose is low, therefore glucagon is activated and seeks to remove the energy reserves from the interior of the cell.
