Answer;

The role of an indicator is to establish the equivalence point when two substance has reached its neutralization process.

Explanation;

-The purpose of an indicator is to determine how acidic or basic the product or solution is. Indicator solutions work by actually reacting with the components of food that they test for, creating a new substance of a different color. This is a chemical reaction.If the substance that they test for is not present in the food, there will be no reaction, and therefore no color change. 

-The test strips will be more likely to be dark blue or black for  Grape, Tomato, Summer squash, Orange Bell pepper as they all contain starch. Color intensity may vary depending on the level of starch found in the samples.

Veseljchak [2.6K]
Given that a blowfly starts its lifecycle only if there are appropriate conditions met, one of which is suitable temperature, the correct answers as to what can impact the timing of the blowfly lifecycle is the air temperature.
I don't see how humans will impact when this fly is going to be born, so A and C are incorrect. Leaves also doesn't really affect blowflies, which is why D is incorrect as well.

"susan is consuming 70 grams of protein per day on her 2,000-kilocalorie-per-day diet. what percent of susan's diet is protein?"
nirvana33 [79]
The answer to this question would be: 14%
Protein will give a calorie about 4kcal/gram. Then, the total calorie of protein from Susan meal would be: 70 grams * 4kcal/g= 280 <span>kilo calorie</span>.
To find the percentage you will need to divide the total calorie diet with the protein calorie. The calculation would be:

protein percentage= protein calorie/ total calorie 
protein percentage= 280kcal / 2,000kcal = 14%
