Wow! this si a huge question but analyzing all the datils from ths option you give me I have to say that C option: <span>Heat energy became trapped in the atmosphere by greenhouse gases and was used as an energy source in the building of macromolecules, is the one that gets closer to what the scientists have said recently. Take into account for example, the examinations of Dr. Stanley Millers. I think this can help you</span>
Answer:
option B) The oxygen end of the molecule has a partial negative charge and the hydrogen end has a partial positive charge.
Justification:
The electronegativity of an element accounts for its relative ability to attract electrons.
Being oxygen more electronegative than hdyrogen (the electronegativity of oxygen is 3.44 while the electronegativity of the hydrogen is 2.20), the electron density will be displaced toward the oxygen, letting it with a partial negative charge and the hydrogen with a partial positive charge.
Finally, since the charge is not symmetrical distributed around a center of the molecule, the molecule ends being polar.

Answer:
A grassland is a biome where dominant vegetation is grasses, a consumer of this biome can be a herbivore (e.g., a rabbit). Coral reefs are home to millions of species of marine animals.
Coral reefs, seaweed and forest biome
Coral reefs are fundamental for protecting wildlife in marine ecosystems.
Seaweed is a common plant in the Euphotic Zone (Sunlight Zone, also called Epipelagic Zone), along with algae and phytoplankton.
Temperate broadleaf forests are represented by areas with marked warm and cool seasons that show moderate annual average temperatures (3 °C to 25 °C).
Examples of producers in a temperate broadleaf forest may be Eucalyptus species, whereas consumers may include, for example, elk
