Answer:
Q1) True
Q2) Metabolism
Q3) Physiological response
Explanation:
Q1) Energy cannot be created (first law of thermodynamics). Life needs an energy source to transform. Without the energy from the sun or any other sources, life would cease to exist. (True)
Q2) An organism chemical reactions consist, in general, breaking down complex molecules (catabolism) releasing energy or to form complex structures from simpler molecules (anabolism) which require energy . The total of this reactions is called metabolism.
Q3) Hibernation is physiological state of inactivity and metabolic depression in some organisms, which result as a response to low temperatures and unavailability of food.
<span>The appropriate answer is c. sonar. Oceanographers use sonar to determine the ocean depth. A sonar signal is sent from the ship. Oceanographers record the time taken for the signal to leave the ship and for it to return. Knowing the speed of sound in water, they are able to calculate the depth of the water. This method is also used to generate bathymetric images of the ocean floor. </span>
