Phosphagen system. Glycogen-lactic acid system. Aerobic respiration.
Explanation:
Answer:
Explanation:
This is due to the fact that water has high specific heath capacity,which makes it to accommodate large amount of heat energy produced by the catabolic reactions which liberated heat.
General, the amount of heat energy needed to raise the temperature of a particular substance over a given amount is called the specific heat capacity of that substance. Therefore for water, the amount of heat energy needed to raise the mass of 1kg of water by 1 degree is called the specific heat capacity of water.
Since large hydrogen bonds held water molecules together,it takes a long time of heat energy to break these bonds free to raise the temperature of water.Hence, water in living cells is able to accommodate large amount of heat energy to stabilise the temperate of the cells.
Answer: d. none of the other answers
Explanation:
Enzymes that turn chemical energy into mechanical work are molecular motors.
There are three main components of cytoskeleton including microtubules, actin filaments and Intermediate filaments. Only actin filaments and microtubules carry the motor-driven transport on the cytoskeleton.
The most important feature of intermediate filaments is to provide the plasma membrane with mechanical support where it comes into contact with the extracellular matrix and other cells.
Unlike microtubules and microfilament , intermediate filaments are not involved in motility of the cells, hence do not associat with molecular motors.
Hence, the correct option is d.
21. B. recessive
22. D. DD and dd
23. D. FF and ff
