this would be Prokaryotes because bacteria are single celled organisms
Cellular respiration depends on two chemical reactants; glucose and oxygen. Glucose and oxygen are made available to plants and animals for cellular respiration thanks to photosynthesis. Photosynthesis is the chemical reaction that uses solar energy to convert water and carbon dioxide into glucose and oxygen. Without photosynthesis, the available glucose and oxygen on the planet would quickly deplete to the point that life could not be sustained on Earth.
10 km = 10 × 1000 m = 10 000 m
10 000 m = 10 000 × 1000 mm = 10 000 000 mm
He discovered dominate and recursive traits along with co dominate and other forms of dominance shown in the pea plants
We can learn what animal it was
