Answer:
Plant ➜ Butterfly ➜ Frog ➜ Snake
Explanation:
Food chain is a way of representing a logical sequence of living beings that serve as food for each other, allowing a flow of energy through various trophic levels.
Each living being presents a trophic level, thus establishing a route of energy and organic matter that passes in decreasing amount from the lowest trophic to the highest trophic. These systems show how each living being is important in the ecosystem and the elimination of one of them can unbalance the entire ecosystem, affecting the food chain and energy transfer.
We can use the food chain as an example: Plant ➜ Butterfly ➜ Frog ➜ Snake. Where the plant serves as food and energy source for the butterfly, which serves as food and energy source for the frog, which in turn serves as food and energy source for the snake.
This is an example of displacement reaction
<u>Explanation:</u>
- The chemical reaction in which the one element replaces the other element in a compound is called a displacement reaction. This reaction is also called a replacement reaction.
AB + C -----> AC +B
2ZnS + 3O2 -----> 2ZnO + 2SO2
- This happens when A is more reactive than B and gives a stable product. Here the zinc sulfide compound reacts with the oxygen element to the stable product of zinc oxide and sulfur dioxide.
- In short, the more reactive element displaces the less reactive element is called a displacement reaction.
The correct answer of the given question above would be FINGERPRINTS. Molds might be used for evidence such as fingerprints. This is now a possibility of replicating fingerprints which is called a fingerprint mold. Hope this is the answer you are looking for.
Answer:
C₃H₆O₃
Explanation:
Data:
EF = CH₂O
MM = 90. g/mol
Calculations:
EF Mass = (12.01 + 2.016 + 16.00) u = 30.03 u
The molecular formula is an integral multiple of the empirical formula.
MF = (EF)ₙ
MF = (CH₂O)₃ = C₃H₆O₃
