✔ 最佳答案
1. (Toxin means 毒素 in Chinese, Do you mean "Are all metals toxic?")Not all metals are toxic. Toxic metals include mercury, etc.
(不是所有的金屬是有毒的. 有毒的金屬有汞(水銀)等)
2. Cheese (芝士), Yoghurt (乳酪), Milk (牛奶), Tofu (豆腐), etc.
3. Calcium. It is because the bone will be easily fracture if we do not obtain sufficient calcium. (鈣, 因為吸收不足的鈣會容易造成骨折)
