In the process O2 is taken in and CO2 is released. Carbon is also released as CO2 when organisms die and decay (work of decomposers). A: The carbon dioxide-oxygen cycle is the cycle in which living things (such as plants and animals) take in oxygen and let out carbon dioxide..
Beetroot juice 'helps lower blood pressure': A glass a day can reduce it by 7%, say researchers. Drinking beetroot juice every day could help to lower blood pressure, say researchers. They found a dose of eight ounces â around one cup â may help people with high blood pressure, cutting their readings by about 7 per cent. Tests suggest the effect is produced by beetrootâs naturally high levels of nitrate.
In the study, 14 healthy volunteers drank 500 milliliters (2 cups) of Planet Organic beet juice or water within 30 minutes. The researchers checked the participants' blood pressure every 15 minutes one hour before they drank the juice and every 15 minutes three hours after drinking the beet juice. They also checked every hour to six hours and then at 24 hours after they drank the beet juice.
