The answer is light reactions
Answer:
Lactic acid accumulation in the leg muscles
Explanation:
Muscle cramps are painful feelings caused by sudden contractions of the muscle. Cramps are caused by several reasons, however, based on the description of Akashay's activity, it is caused by ACCUMULATION OF LACTIC ACID in the leg muscles due to strenuous exercise.
According to this question, Akashay decided to run a marathon without any prior training. However, he started to get cramps on his thigh coupled with rapid breathing. There is a lack of oxygen in his cells, hence, anaerobic respiration was used leading to the formation of lactic acid. The buildup of lactic acid is what causes the painful sensation called CRAMP.
It’s b kinetic energy is something moving
Answer:
B. High to Low Concentration (crowded --> comfy)
Explanation:
Passive transport is defined as the transport of molecules from high concentration to low Concentration across cell membranes without using energy. Passive transport is based on the second law of thermodynamics. An example of passive transport is diffusion.
Hence, the correct answer is "B. High to Low Concentration (crowded --> comfy)".
