Answer:
I dont fully understand but should be some sort of thinking stage
It occurs when part of the muscles of the lower leg (gastrocnemius or soleus) are stretched beyond their stability to withstand the tension. This stretching can result in small micro-tears to the muscle fibers or, in a severe injury, a complete rupture of the muscle fibers.
<span>The correct answer is D, multiple fission. During this process, the nucleus divides many times y mitosis. This is followed by the separation of cytoplasm, and this creates several daughter cells. The process occurs in many protists.</span>
1. The correct answer is pH.
The activity of the enzymes might be affected by environmental changes such as change in pH. Each enzyme has the point when it is the most active and this value is known as the optimum pH. Extremely high or low pH values can lead to loss of enzyme activity and stability.
Phosphofructokinase is sensitive to acidity, meaning that it is inhibited by low pH levels.
2. The correct answer is temperature.
Enzyme is sensitive to the environmental conditions such as temperature changes.
Temperature is a factor that usually increases the rate of enzyme-catalyzed reactions by increasing the activity of enzymes. But, after reaching the optimum temperature, reaction rate abruptly declines. This happens because enzymes are deactivated or denatured at a certain temperature (above 40° C).
