Answer 1

Answer:

1. Yes the amount of salt affect because though health authorities continue to push for lower sodium intake, reducing sodium too much- below 3 grams per day- may negatively impact health. studies shows that people who consume less than 3 grams of sodium per day are attar craters risk of heart disease and early that then people with an intake of 4-5 terms.

2. 1 inch ice cube, submerged in a cup of cold water take about 15-20 minutes to melt. In a room temperature water would melt in 5-10 minutes.

3. The dependent variable is the event expected to change when the independent variable is manipulated.
