Study the diagram, which represents the general equation for photosynthesis. What do the letters Y and Z represent? Y - glucose Z - oxygen Y - glucose Z - carbon dioxide Y - carbon dioxide Z - hydrogen Y - carbon dioxide Z - oxygen

The correct answer is Y - glucose, Z - oxygen

Explanation:

In photosynthesis, plants- and also other organisms- take carbon dioxide (CO₂), water (H₂O) and light (which is absorbed by chlorophyll pigments, those give plants their green color), and they convert inorganic materia in organic materia (chemical energy) in form of sugar. The overall process is described by the following global equation:

6 CO₂ + 6 H₂O → C₆H₁₂O₆ + 6 O₂

carbon dioxide + water → glucose + oxygen

affects the water bodies: excessive use of fertilizers causes eutrophication. the fertilizers which are used on plants affect the quality of land on which it is used, further causing erosion of soil. the fertilizers used on plants contain harmful chemical fumes which affect the environment.

the corpus luteum secretes estrogens and progesterone. the latter hormone causes changes in the uterus that make it more suitable for implantation of the fertilized ovum and the nourishment of the embryo. if the egg is not fertilized, the corpus luteum becomes inactive after 10–14 days, and menstruation occurs.

i hope this : )
