Explanation:
Quantitative refers to numbers and measurements, so height would be a quantitative observation.
Hope this helps! :)
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.
If the arteries become less stretchy, the heart will have to work harder to eject blood.
Answer:
The Circulatory or Cardiovascular System
Explanation:
This system allows the circulation of blood to every cells of the body with the transport of oxygen and nutrients essential for its survival. These nutrients include glucose, amino acids, vitamins, minerals and so on produced by the body through metabolism.
The circulatory system comprises also of the lymphatic system, which allows for the flow of lymphs.
The circulatory system is made up of systemic and pulmonary circulation. The heart and blood vessels being the major structures in this circulation. The blood moves to the lungs and get oxygenated (pulmonary circulation) and it then returned back to the heart for transport to other parts of the body known as the systemic circulation. Hemoglobin, which carries oxygen in the blood and also carbon iv oxide for excretion out of the plasma. From the digestive system, the nutrients are absorbed into the blood plasma and then transported for the cell use or for storage.
