)as marine animals swim in the ocean, their muscles are doing work and converting energy from the animals' food into which of the following types of energy?
nuclear energy
chemical energy
solar energy
kinetic energy

Kinetic energy

As marine animals consume food, the food is required to produce chemical energy in the form of ATP. This chemical energy provides energy to do work in the form of kinetic energy. Therefore, muscle movement of animals requires kinetic energy.

easy

explanation:

the correct answer is 4) heat and pressure

metamorphic rocks arise from transformation of existing rocks types, in a process called metamorphism. during metamorphism the original rock(prolith) change into metamorphic rock by heating (150-200c) and pressure of more than 1000 bar. the original rock can be sedimentary, igneous, or existing metamorphic rock.
