A usual heart rate in case of adults varies from 60 to 100 beats per minute. Usually, a lower heart rate at rest signifies more effective functioning of heart and better cardiovascular fitness. For example, a well-trained athlete may possess a usual resting heart rate closer to 40 beats in a minute.
The following is the correct order to measure the heart rate:
1. Make a fist.
2. Find a radial artery.
3. Feel a pulse.
4. Count for 10 seconds.
5. Multiply by 6.
Answer: The environmentalists are concerned about the introduction of genetically engineered trees because their introduction into the environment could have unexpected interactions with the other plants and animals present in the ecosystem.

Answer: The enzyme increases the effectiveness of reactant collisions thereby increasing the number of reactant molecules that reach activation energy.
A reaction occur if the substrates needed collide with each other. Enzyme is like a mold that can hold the substrate so that it will be easier to collide. The effect of enzyme could be seen in the activation energy needed to do the reaction because enzyme lower it very much. This will help speed up the reaction so it create product faster.
