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.

What role does oxygen play in a plants life?
aleksandrvk [35]
Plants need oxygen to survive , no oxygen mean the plant will diePlants do need oxygen to survive. They respire (take in oxygen, give off carbon dioxide) the same way that animals do. The difference is that during the day, plants also perform photosynthesis, in which they take in carbon dioxide and give off oxygen.Plants require oxygen for respiration to carry out their functions of water and nutrient uptake. In soil adequate oxygen is usually available, but plant roots growing in water will quickly exhaust the supply of dissolved oxygen and can be damaged or killed unless additional air is provided. A common method of supplying oxygen is to bubble air through the solution. It is not usually necessary to provide supplementary oxygen in aeroponic or continuous flow systems.Oxygen is vital ingredient in plant survival

Instructions:Drag each tile to the correct box.
rjkz [21]
The correct sequence is sources emit greenhouse gases; global temperatures rise; snow and ice melt; and sea levels rise. The natural and man made sources emit greenhouse gases that are responsible for the greenhouse effect. The increase in the Earth's temperature due to these gases absorbing more heat from the sun caused climate change like melting of snow and ice which contributes to the rising sea levels.
