Answer:
The adaptations prove the physical composition of the neutral analysis.
Explanation:
Answer:
The correct answer would be "Each parent is either M or MN".
Co-dominance is the condition in which both the alleles express themselves completely when present in the heterozygous condition.
The blood group of the offspring can be of M type in two conditions:

B: nucleus, mitochondria, cell membrane
c and d both have chloroplasts which are unique to plant cells
a is wrong because only plant cells have cell walls
Answer:
False
Explanation:
Scientist believe that the primitive atmosphere lacked free oxygen. Oxygen is a highly reactive molecule that would have made difficult for complex macromolecules to appear and then create life. Rocks from the precambrian period support this theory.
Anaerobic cells appeared first, then photosynthesis appeared filling the atmosphere with oxygen and the aerobic organism develop cellular respiration to obtain energy, a process more efficient than anaerobic respiration.
