1.If the roots hairs take up water from the soil by osmosis, what would you expect to
happen if so much nitrate fertilizer was put in the soil that water becomes stronger

2. Checking pulse is a preliminary test for whether a person is alive. Explain

the oxygenated blood then leaves the lungs through pulmonary veins, which return it to the left heart, completing the pulmonary cycle. this blood then enters the left atrium, which pumps it through the mitral valve into the left ventricle. from the left ventricle, the blood passes through the aortic valve to the aorta.

deoxygenated blood leaves through the right ventricle through the pulmonary artery. from the right atrium, the blood is pumped through the tricuspid valve (or right atrioventricular valve), into the right ventricle.
