The main factor that controls the rate of breathing is..
A.) concentration of carbon dioxide.
If we think about it.. When we breath in oxygen, right away it enters your lungs and turns into carbon dioxide. Well since your lungs need to process oxygen and bring oxygen into the blood stream. Then as soon as the oxygen comes inside (inhale) the oxygen turns into carbon dioxide and you breath it out (exhale) to get a new oxygen load.
Makes sense? lol
Good Luck! :)

She needs to be sure that her food selections provide a source of Calcium & Vitamin B12 since she is now avoiding dairy foods.
Explanation:
Dairy foods are a source of calcium and vitamin b12, among many other macro and micronutrients. When it comes to this specific mineral and this vitamin, they are super important because you won't find them in many other food or products. Actually vitamin B12 is a frequent problem in vegan people, because they don't consume any animal or derivative, which are the main products that contain it.
In the case of Lydia, if she stops consuming dairy products, she can obtain calcium from come cereals, seeds, vegetables and fish. Regarding vitamin B12, you can find it in meat and fish. In both cases you can consume a supplement, but this case will only be prescripted when it is impossible to fulfill the recommendations with food.
