To test for the presence of reducing sugars, a food sample is dissolved in boiling water. Next, a small amount of Benedict's reagent is added and the solution begins to cool. During the next four to 10 minutes, the solution should begin to change colors. If the color changes to blue, then no glucose is present. If a high amount of glucose is present, then the color change will progress to green, yellow, orange, red and then a dark red or brown.
Answer:
Human blood contains a buffer of carbonic acid (H2CO3) and bicarbonate anion (HCO3-) in order to maintain blood pH between 7.35 and 7.45, as a value higher than 7.8 or lower than 6.8 can lead to death. In this buffer, hydronium and bicarbonate anion are in equilibrium with carbonic acid.
Gymnosperm plants important adaptation of the seed allowed plants to spread quickly across the land.
What is a gymnosperm ?
- Unlike angiosperms, or flowering plants, whose seeds are enclosed by fully developed ovaries, or fruits, gymnosperms, or any vascular plant, reproduce by the use of an exposed seed, or ovule.
- Many gymnosperms bear their seeds in cones, which are known as "raw seeds" because they are not visible until they are fully developed.
- Yew ,Gingko biloba, Cycads , Pines, Spruce are examples of gymnosperm

- The plant can find it exceedingly challenging to live in a foreign environment because of these adaptations.
- This explains why some plants are only found in particular places.
