Answer
Frequency of stimulus can change the force of muscle twitch.
Explanation
Twitch is tension produced by the contraction of a small muscle or it is muscle fasciculation. Its strength depends on the stimulation frequency. If the frequency is higher then temporal summation takes place and produce higher tension in the muscle. If the frequency is weak then less tension is produced in the muscle. This force also depends on the cross-sectional area of muscle.
Answer:
Parks and protected areas are essential to conserving biodiversity and slowing the pace of extinction. Globally, parks and protected areas safeguard habitat for wildlife and provide them with space to feed, raise their young, and exist with minimal human interference.
Adenosine triphosphate (ATP) is the main energy carrier molecule used living things. The difference between ATP and ADP, or adenosine diphosphate, is found in the number of phosphate groups, 3 for ATP and 2 for ADP.
Let's think of ADP and ATP as a battery - ATP represents the full battery, ADP represents a partially full battery.
ATP has a extra Phosphate group, which it gives off for energy where it is needed in the cell. Then it becomes ADP, ADP regains the phosphate through cellular respiration and becomes ATP again. The cycle repeats indefinitely.
