Answer:
- A, B, C and D are: elements or molecules
- A and B are: reactants
- C and D are: products
Explanation:
The expression "A + B <--> C + D" represents a chemical equation. A chemical equation represents the "mixture" of molecules or elements that will react and form other molecules and elements, so we can say that A, B, C and D represent molecules or elements.
But not only that. In a chemical equation, the elements and molecules that are before the symbol "<-->" represent the reagents in the equation. Therefore, A and B are the reagents. The elements or molecules found after the symbol "<-->" are the products of the reaction. Therefore, C and D are the products.
When TWO FERTILIZE CELLS fuse together and make as one cell. It would undergo to many process and multiplication of cell until it would produce an multi cellular organism that could also produce a fertilize cells and be use for another fertilization
Plants has the component of sugars
The only answer that makes any sense is D. The rest of the answers do not make any sense. Be wary of answers that use the word "always." For example, domesticated swine are raised on farms and wild pigs live in the woods. But they are related and would have the similar genetics.
Uh I might be wrong but I believe it may be between the first two answers.
