<span>Eating away from home is playing an increasing large role in the diet and the household budgets of American families. Back in 1970 approximately 26 percent of all food spending was on food away from home; by 2012, that amount had risen to 43 percent. The increase can be attributed to a greater percentage of women employed outside the home, more two-earner households with the resulting higher incomes, as well as more affordable and convenient fast food outlets. The downfall of this statistic is the contribution all that fast food makes to higher levels of obesity and lower dietary nutritional quality.</span>
Answer:
Negative feedback loop
Explanation:
When the blood calcium level is low, the receptors of the parathyroid gland sense it and increase the production of cAMP. The increased cAMP levels stimulate the secretion and release of parathyroid hormone from the parathyroid gland into the blood.
The increased parathyroid hormone levels stimulate the number and activity of osteoclasts and speed up the process of bone resorption resulting in the release of calcium ions from bone into the blood to raise the blood calcium levels.
Here, the response (increased blood calcium level) reverse the stimulate and hence, the process is under the regulation of negative feedback loop

Answer:
The majority of the carbon dioxide we exhale is produced in the cell during the process of respiration.
Explanation: Carbondioxide is a waste material which is produced in the process of respiration. In respiration, glucose molecules is broken down for releasing energy with the help of oxygen molecule which produces carbondioxide, water and energy in the form of ATP. Carbondioxide is removed through lungs and energy is used by the cell.
