Answer:
the answer is actually c
Explanation:
Cold air is more denser than hot air because ,when cold air of some density, say 'd' is heated, the molecules/atoms move apart from each other and so the volume expands. i hope that helped you

Answer:
Regulate heat throughout it's body,
Explanation:
Countercurrent Heat Exchange is a normal and varied mechanism in organisms that utilizes parallel pipes of flowing fluid in opposite directions in order to save energy, such as blood flow. For example, a whale's tongue uses this system through the blood flow to the tip of the tongue, where the countercurrent heat exchange system heats up blood returning to the body.
Answer:
Both speed and mass causes the kinetic energy to change.
Explanation:
The energy an object because of its motion is called as Kinetic energy. A object that moves be it horizontal or vertical direction possess kinetic energy. Some forms of kinetic energy are rotational, vibrational, translational. The kinetic energy(K) of the object depends on two components i.e., the mass (m) of the object involved and its speed(v)
The relation between the mass, speed of the object can be represented as

Kinetic energy$=\frac{1}{2} m \times v^{2}$
Thus when there is a increase in the mass and speed, the kinetic energy will also increase
