It provides reference values of nutrients in terms of Estimated Average Requirement (EAR), Recommended Dietary Allowances (RDA), Adequate Intake (AI) and the Tolerable upper limit intake levels (UL).

Calcium is an important nutrient required for healthy bones and teeth. It is required for blood clotting, releasing hormones, transmission of nerve impulse and other functions of the body. The sources of calcium include the fortified cereals, tofu, milk powder, cheese, dried whey, fish, green leafy vegetables and others. For women and men in the age ranging from 19 to 50, the calcium DRI is 1000 milligrams per day.

Which is not evidence for the endosymbiotic origins of mitochondria and chloroplasts?
Zolol [24]

Mitochondria and chloroplast have similar DNA, which is not evidence for the endosymbiotic origins of mitochondria and chloroplasts.

According to the endosymbiotic theory, a chloroplast and a mitochondria were the independent prokaryotes. Both can be ingested by a large prokaryote and resist digestion. As a result, they continued as endosymbionts and eventually lost some of their autonomic properties. They divide by binary fission, have their own genetic material, possess 70s ribosomes, and Both include their own transcriptional and translational machinery.

Therefore, considering endosymbiotic origin theory, Both Mitochondria and chloroplast have similar DNA is not a piece of evidence.
