Explanation:
During photosynthesis, molecules in leaves capture sunlight and energize electrons, which are then stored in the covalent bonds of carbohydrate molecules. That energy within those covalent bonds will be released when they are broken during cell respiration. How long lasting and stable are those covalent bonds? The energy extracted today by the burning of coal and petroleum products represents sunlight energy captured and stored by photosynthesis almost 200 million years ago.
Plants, algae, and a group of bacteria called cyanobacteria are the only organisms capable of performing photosynthesis. Because they use light to manufacture their own food, they are called photoautotrophs (“self-feeders using light”). Other organisms, such as animals, fungi, and most other bacteria, are termed heterotrophs (“other feeders”) because they must rely on the sugars produced by photosynthetic organisms for their energy needs. A third very interesting group of bacteria synthesize sugars, not by using sunlight’s energy, but by extracting energy from inorganic chemical compounds; hence, they are referred to as chemoautotrophs.
<h3>Answer:</h3>
Jean has a sample of a liquid. If she changes the liquid's phase by <u>Evaporating</u> it, the molecules will spread out, allowing the sample to expand and fill a container of any shape or volume.
<h3>Explanation:</h3>
Evaporation is a kind of condensation that happens on the surface of a liquid as it turns into the gas state before approaching its boiling point. The enclosing gas must not be immersed with the evaporating matter. Evaporation is a major element of the water cycle and is continually happening throughout the environment.
