<h3><u>Answer;</u></h3>
It combines with water to form glucose.
<h3><u>Explanation;</u></h3>
- Photosynthesis is a process by which green plants make their own food by using solar energy from the sun, together with water and carbon dioxide.
- Carbon dioxide, water and light are all needed for photosynthesis to take place. During the process solar energy from the sun is used to convert carbon dioxide and water into the simple sugar glucose.
- <em><u>Substance A is the above question represent carbon dioxide which combines with water in presence of light to form simple sugars and oxygen gas.</u></em>
- The equation for the reaction is;
6CO2 + 6H2O + light energy = C6H12O6 + 6O2.
Answer:
Villi
Explanation:
In the small intestine, villi are found present. These villi which appear like a finger-like tissue structure are about 0.5–1.6mm in length in human beings.They have mucosal cells that help in absorption of nutrients. A villus has several microvilli, which increases the surface area of the intestinal wall for faster absorption of nutrients.
1. yes it is possible because some plants do not have chloroplasts like Prokaryotes. Not all plants need chloroplasts to survive
Answer: Directional selection
Explanation:
In the population genetics, directional selection is the mode of selection during which the extreme phenotype are favored more than the other phenotype.
This causes the allele frequency to shift towards the time in the direction of that particular phenotype.
Here, in the question the acid tolerant plant species is favored over the other phenotype.
Hence, the correct answer is option D
