Answer:
100,000
Explanation:
pH of coffee = 5
pH of solution = 10
Concentration of H+ ions between successive pH values are in multiples of 10
Hence, the pH difference :
pH of solution - pH of coffee
(10 - 5) = 5
Hence, difference in H+ ions will be :
10^5 = 10*10*10*10*10 = 100,000 times
Answer:
When the frequency of stimulation of a muscle increases -without it having the opportunity to relax- a process called summation (addition) occurs, promoting an increase in the generation of force in the isolated skeletal muscle.
Explanation:
Summation is a phenomenon that occurs as a consequence of the arrival of successive stimuli that produce the contraction of the skeletal muscle before it achieves its partial or total relaxation, between subsequent stimuli.
<em>When the summation occurs in the muscle, the force generated on it increases its magnitude proportionally to the number of stimuli received, maintaining the muscle contraction in time</em>.
Tetany is the prolonged contraction of a muscle in an abnormal way, by the summation of stimuli received , as some bacterial toxins can produce. The summation can be temporary -when multiple stimuli reach the muscle in a determined time- or spatial, when the amount of stimuli activates a greater amount of motor units.

Answer:
plants For example, phototropism is the plant's response to stimulus, i.e. sunlight. A plant hormone “auxin” keeps the plant's direction towards the sun by activating the growth in a particular part of a stem. Similarly, gravitropism in plants responds to the stimulus, i.e. gravity
