Would prescribing calcium salt helps to treat the primary bone problem in scurvy?​
Nikolay [14]

Answer:

Explanation:

Scurvy is a disease that causes weakness, gum disease, changes to hair, and bleeding from the skin, and weak bones. This is caused strictly from a Vitamin C deficiency and can thud be treated/cured by implementing more vitamin C into your diet. Calcium Salt is a supplement that can help with the primary bone problem in Scurvy but is only a small inclusion in vitamin C and will not treat Scurvy. As mentioned previously incorporating more Vitamin C into your diet will treat/cure all symptoms of Scurvy including bone problem.

I hope this answered your question. If you have any more questions feel free to ask away at Brainly.

Then at medium speed mitochondria, lysosome, peroxisomes form the pellet and after that at higher speed microsomes, small vesicles form a pellet. At last at very high speed, ribosomes, viruses, and macromolecules form their pellet.  

  • Mitochondria will be the most suitable option because mitochondria are the only substance that can produce ATP.
