Atrial natriuretic peptide released by certain atrial cells
in response to rising BP or volume, causes systemic vasodilation and inhibits
renin, aldosterone, and ADH release. Hence, it enhances Na+ and water
excretion, reducing BP and bv. Falling
arterial pressure promotes vasoconstriction and conserves Na+ and water.
The following tests can determine the mineral in a rock specimen:
1. How does the rock crumble or split under pressure?
2. What is the texture of the rock?
3. Observing it under a magnifying lens.
4. Determine the color of the rock
Test 1 and 3 determines if the rock is granular and the types of grains in the rock. Test 3 also determines if the rock has layers hence sedimentary rock.
Determining whether color of the rock is dark or light also helps identify the mineral and type of rock.
Overpopulation, pollution, burning fossil fuels, and deforestation. Changes like these have triggered climate change soil erosion, poor air quality and undrinkable water.
