Where does the energy stored in fossil fuels come from?

sedimentary rocks are mined and processed to make it
stored solar energy in phytoplankton, zooplankton, and other organic material
the stored energy in fossils
petroleum and natural gas

Answers

Answer:

stored solar energy in phytoplankton, zooplankton, and other organic material

Explanation:

The energy in fossil fuels comes from the sun, which drives photosynthesis to change carbon dioxide and water into the molecular building blocks of ancient plants and animals.

Gregor Mendel

Explanation:

Mendel's Experiments: The Study of Pea Plants & Inheritance. Gregor Mendel was a 19th-century pioneer of genetics who today is remembered almost entirely for two things: being a monk and relentlessly studying different traits of pea plants.

In very early attempts to classify organisms, the greek philosopher, Aristotle, identified all animals as "aire dwellers, land dwellers, or water dwellers". Under this system, all of the following organisms would have been placed in the same group: bat, grasshopper, eagle, butterfly, flying squirrel, and sparrow. In the space below, construct a dichotomous key that can be used to identify 6 animals.

(picture included)DO IN 10 MIN At the bottom of the air track, the glider hits and stretches a rubber band, that causes the glider to change direction. When the rubber band is maximally stretched, the glider's kinetic energy is zero, because it is momentarily at rest. Since the glider is at the bottom of the air track, its (gravitational) potential energy is also zero. So the sum of the kinetic energy and gravitational potential energies is zero, yet energy is conserved. Where did the energy go? What is RNA? What similarities does it have to DNA?
