Answer: The reaction that causes a firework to explode requires less energy to start, and occurs more rapidly than the reaction that causes a candle to burn
Explanation: As can be seen from the energy diagram, the reaction which leads to burning of candle and shown by a blue curve require higher activation energy , i.e energy required to cross the energy barrier and get converted to products. It also takes more time for completion.
The reaction which leads to exploding firework and shown by a orange line and requires less activation energy , i.e energy required to cross the energy barrier and get converted to products. It takes less time for completion.
Answer:
Hibernation allows an animal to keep its core body temperatures colder.
Explanation:
Bears Hibernate, and many more animals do too
Answer:
The correct option is: e. molecules move across the plasma membrane against their concentration gradient
Explanation:
Active transport refers to the <u>movement of the particles or molecules from higher concentration to lower concentration, across the plasma membrane of a cell.</u> This transport requires cellular energy as the movement of the molecules is <u>against the concentration gradient</u>.
Active transport can be divided into primary and secondary active transport.
