Answer: Option b
Explanation:In chemistry,
before any reaction would occurs, reactat must be able to overcome some certain amount of energy which is called the activation. The activation energy is usually the heat that is suppled.it is also refered to as the minimum energy needed before any reaction can take place. For reaction to take place, there must be an equilibrium( at constant temperature and pressure.
Answer:
What are some differences between a food chain, web, or energy pyramid? Food chains show a limited feeding relationship between only a few organisms. Energy pyramid is the visual representation of the amount of energy, population, or biomass at each trophic level.
Remember the cell theory by Virchow that states that all cells come from pre existing cells, if a single cell dies, it can be replaced unless it's a brain cell.
Exponential growth = individuals are not limited by food or disease; the population will continue to grow exponentially; Logistic growth = the population begins to grow exponentially before reaching a carrying capacity and leveling off.
