Answer:
The correct answer is A. 3O₂ + 2Al → 2AlO₃
Law of conservation of mass states that mass can nether be created nor destroyed in a closed system or chemical reaction i.e. the total mass of the matter always remains the same throughout the chemical or physical change.
For example, in the given reaction 3O₂ + 2Al → 2AlO₃ the total mass of the reactants is equal to the total mass of the product.
Mass of oxygen = 16 x 3 = 48 AMU
Mass of aluminium = 2 x 27 = 54 AMU
Total molecular mass of the reactants = 102 AMU
Total molecular mass of the product = 2 x 27 + 6 x 8 = 102 AMU.
Hence, the total mass of the matter remains the same.
Hormones stimulates stem elongation and pollen tube growth gibberellins.
A type of plant and fungus hormone is gibberellin. Although its function in the development of fungi is not fully understood, extensive research has been done on it in plants. The other four major groups of plant hormones are auxins, cytokinins, ethylene, and abscisic acid. Gibberellin is one of these hormones. Gibberellin can make seeds come out of dormancy, lengthen cells, promote division, and even play hormonal and signaling roles in the fruiting and senescence processes. Numerous areas of the plant produce different types of gibberellin molecules. There are currently more than 100 distinct gibberellin molecules.

Answer:
D. Beautiful leaves
Explanation:
All of the other answers are factual. However, something such as beauty can only be decided in an opinionated and biased way.
Answer: Oceans
Explanation:
Climate is primarily determined by the interaction between air and ocean. The warm wind circulate and makes the temperature feasible for life.
Oceans heat the air above it and it circulates from the equator region to the polar region to make the temperature optimum. The circulation of air due to ocean leads to climate change.
hence, these two factors are responsible for the climate of a region.
