Answer: Option C.
Energy flows in one direction in ecosystem.
Explanation:
In the ecosystem, energy flow in one direction. Energy is transfered from one trophic level to another.
Energy is transfered from producers, majorly plants,convert sunlight to chemical energy during photosynthesis and transfer it to herbivores( goat, sheep ) when they eat plants,the herbivores after using the energy transfer energy to the carnivores when the carnivores feed on the herbivores and to decomposer who feed on dead animals.
i believe it is a but please tell me if im wrong
Answer:
See attached picture
Explanation:
An optimal temperature graph plots the rate of the enzyme reaction against the temperature. We know that the optimal temperature of this enzyme is 37C, so we know that at this temperature, the rate will be highest.
Additionally, there will be a minimum temperature required for the enzyme to work at all, which is why the line graph slowly increases the rate until its optimum at 37C.
Finally, at higher temperatures, the enzyme will become denatured and its activity will be diminished. This is why the activity drops at high temperatures and is non-existent at very high temperatures.
Answer:
<em>The correct option is A) they are all classified as pure substances.</em>
Explanation:
Pure air is a term which is used to described air which is free from pollutants or other contaminants. All the substance from which air is made are considered as pure substances. Hence, option A is correct.
Other options, like option C, is false because the components of the air are no chemically bonded to one another. They exist freely. Options D is false because not all the components of air can be classified as an element. For example, carbon dioxide is not an element.
