imagine that you could treat chloroplats with an indiicator dye that turns red in acidic conditions, yellow in neutral ocndition
zmey [24]

The amount of light between points 1 and 2 is adequate for photosynthesis to occur at a faster rate than cellular respiration. Acidic conditions typically imply that the solution has an excessive concentration of H+, which makes the solution acidic. By dividing the reaction into half-reactions, the balancing process begins.

This indicates that more CO2 is being consumed than is being produced, which makes the problem more straightforward.

The signal will become purple as a result, from yellow. After point 2, light levels are low enough that cellular respiration outpaces photosynthesis, which results in more CO2 being generated than being absorbed and raising the pH of the solution. The indication will become yellow as a result, from purple.

An indicator dye called bromothymol blue (BMB) changes color from blue to yellow when acid is present. The pH of the solution decreases when carbon dioxide is introduced because it produces carbonic acid. When the pH is greater than 7.6, green, between 6.7 and 7.6, and yellow, less than 6, BMB is blue.

torisob [31]

Answer:

I would choose a food source that has a significant level of carbohydrates, proteins, and vitamins. <em>E.g.</em> bananas.

Explanation:

Food is one of the most important ways to increase our energy. It may be very common to feel lethargic throughout the day when one's diet is not appropriate or balanced.

According to nutriologists, bananas are one of the best foods that boost our energy. Bananas contain carbohydrates, [natural] sugar, minerals, and amino acids. Incorporating this fruit into your diet can be extremely helpful, especially if you practice sports. In fact, recent research showed that consuming bananas before and after exercising helps you maintain your body with high levels of energy throughout the day and, therefore, helps you to have a better performance.
