The answer is most likely: 'with an abundance of plant life without oxygen in the atmosphere '. The atmosphere contained almost no free oxygen during the Archean. It does not appear as if this epoch had an abundance of plant life, but rather mats of single-celled photosynthesising cyanobacteria. So I am not completely sure that either of the given choices are correct.
Inbreeding refers to sexual reproduction between genetically close individuals.
Interbreeding refers to reproduction with another species or race. Interbreeding is basically the same as cross-breeding.
Answer:
A: By breaking and reforming chemical bonds in the molecules
Explanation:
There is energy stored in chemical bonds between food molecules, called ATP. When chemical bonds are created, some energy is stored in those bonds. When one of these bonds are broken, the energy that was stored is released, and can then be used by your body. Your body then uses a different type of energy, called ADP, to reform the bonds, which then go on to become waste products.
I hope this helps!

Answer:
D
Explanation:
bird eggs don't need additional moisture that some reptiles absorb with their eggshells
Answer:
They have approximately similar molecular weight, chemical composition and solubility.
Explanation:
Macro molecules are bigger molecules having more weight. The molecular weight of the macro molecules is more than 10,000 Dalton. They are chiefly the carbohydrates, proteins, lipids, and nucleotide. These are found in the acid-insoluble pool. This means all macro-molecules are acid insoluble. They are all polymers. Their composition is similar, having carbon and hydrogen which forms bonds with other compounds like nitrogen, sulphur, phosphate, OH, etc. They are all basic components of the cell and cell membrane and all are organic molecules.
