Considering the following;
I. Heat is not readily available to all living cells.
II. Heat at excessive amounts denatures proteins.
III. Heat does not provide the activation energy for their reactions.
IV. When a critical temperature is reached, proteins no longer function
Answer;
I and IV
Explanation;
Living cells cannot use heat to provide the activation energy for biochemical reactions because heat is not readily available to all living cells and also when a critical temperature is reached, proteins no longer function.
Too much heat can kill an organism by rendering its organelles, cells, tissues and organs permanently inoperable and un-salvageable. The same process can be observed in tissues at low temperatures, and is the cause of frostbite. This is because enzymes are denatured by high temperature and inactivated by low.
Kinetic energy is absorbed and converted to potential energy in an endothermic reaction.
Answer:
Due to the gravitational force of the sun and the moon the tides behave as blank waves.
Explanation:
Tides waves are usually the up and down movement of waves. Tides wave formed by the gravitational force of the Earth,moon and sun.the sun and moon’s gravitational force pulls up the ocean to tilts towards the earth because of this reason t the tides rise up and down. Moreover the waves in water sticks to its governing principle that 's why it makes sound
