<span>The answer is green, yellow or brick-red. If simple sugars are present, the blue solution will turn green, yellow or brick-red when combined with the food sample and heated. </span>Benedict's solution<span> is used to test for simple sugars, such as glucose. It is a clear blue solution of sodium and copper salts. When heated with the food sample, the blue solution changes color to green, yellow, and brick-red, depending on the amount of sugar.</span>
Answer:
The evolution of the heart is based on the separation of oxygenated blood from deoxygenated blood for efficient oxygen transport. pisces have a dual chambered heartwhile reptiles and amphibians are having a three chambered finally aves and mammals have four chambered hearts.

Answer:
The correct answer would be b. because water provides electrons.
During the light reaction of the photosynthesis, the water is photolysed into high energy electrons, hydrogen ions, and oxygen.
The overall reaction can be written as:
2 H₂O + sunlight → 4 H⁺ + 4 e⁻ + O₂
It takes in water-splitting complex associated with photo-system II rooted in the thylakoid membrane of chloroplast.
The oxygen is released as the byproduct of photosynthesis.
The hydrogen ions help in the formation chemiosmotic potential across the thyllakoid membrane which help in the formation of ATP (adenosine triphosphate).
The electrons are used to replace the electrons lost from chlorophyll a of reaction centre associated with photo-system II. The electrons are lost due to the photo-excitation of chlorophyll a.
The electrons lost from chlorophyll a help in the production of ATP and are used to reduce NADP⁺ into NADPH.
The ATP and NADPH are used in light-independent reaction of the photosynthesis to produce glucose or food.
