C, it guarantees the survival of a species, for example there are a species of moth called the pepper moth, some of them are light and some of them are dark, where the pepper moths live has dark trees, the pepper moths that are lighter in color are likely to be eaten by birds because they are easier to see making the amount of light pepper moths scarce while the dark pepper moths live to breed and have offspring.

Earth is the largest terrestrial planet in the solar system. Earth's huge size enables it to exert enough gravitational force to

denpristay [2]

Answer:

Lower gravitational force due to lower mass.

Explanation:

Mars has lower gravitational force than Earth because of its lower size because mass has a direct effect on gravitational force of an object. Earth has mass of 5.972 × 10^24 kg which is 10 times greater than mass of Mars which is 6.4171 x 10^23 kg. So due to earth's more mass, it has more gravitational force than planet Mars which has lower mass than earth.

Katena32 [7]

Thermal energy is transferred during heating.

What is thermal energy?

Thermal energy refers to the ability to do work. As such thermal energy can also be defined as the ability of something to do work as a result of the movement of its particles.
In other words, thermal energy is the energy possessed by an object or body by virtue of the movement of its constituent particles.
It is the total internal kinetic energy of an object due to the random motion of its atoms and molecules.
Thermal energy is a type of kinetic energy owing to the fact that it results from the movement of particles. Kinetic energy is the energy possessed by an object due to its motion.
Thermal energy forms the foundation of the study of heat energy and thermodynamics. It is one of the oldest forms of energy utilized by mankind.
Its usage existed even before petroleum and nuclear power sources were discovered.

A Carbon Sink is a reservoir which absorbs more carbon than it releases. Suggest how carbon in the bodies of crustaceans and mol

mr Goodwill [35]

Answer:

Crustaceans and Molluscs play an important role in the oceanic carbon sink.

Explanation:

Carbon sinks can serve to partially offset greenhouse gas emissions. Forests and oceans are both large carbon sinks. Algae is pressurized to bottom of the ocean by long term sequestration. Algae then falls to the bottom of the ocean and TRANSFORMS to fossil fuels.

CO2 is not combustible.
creates carbonic acid in the oceans.
Reduces seawater pH, carbonate ion concentration, and thus calcium carbonate (needed for shells for marine creatures, contributes to BOTTOM-UP EFFECT)
