Potential energy
the energy possessed by a body by virtue of its position relative to others, stresses within itself, electric charge, and other factors.
Most of the marine animals have a stream lined body, which means, they have a sharp and pointed at the front. The pointed front of the organism allow to cut the resistance of the water. In case, the body is not pointed at the front and it is blunt, the water current and flow would resist the movement of the organism further. So, for the locomotion purpose, it is important to have a streamlined body. Further smooth and hair less body also decrease the resistance during the movement in the water.
Answer:
B
Explanation: The specific heat of any particular substance is usually defined as the amount of heat energy that is required to raise a unit mass of the material by 1°C. The water has this high heat capacity as a result of which the water bodies such as oceans, seas, and lakes tend to become hot and cold at a much slower rate.
This is the third question of yours I've answered
The root word of Unicellular already tells you the answer. Uni means only one cell. So the answer is one cell.
