Hey there! Simply put, inherited traits come from an ancestor, and acquired are ones that are earned through adaption. Hopefully that makes sense. :)
Carbon dioxide is used to build sugars. I think it's the only one
Answer:
Oxygen levels stay above 15 percent starting 200 million years ago
Explanation:
Atmospheric oxygen levels are related to the evolution on Earth and changes in geochemical cycles that involve climate variations.
The presence of O
2 and evolution of oxygen gave new opportunities to the life on Earth. Oxygen levels in atmosphere have fluctuated between 15% and 35% of atmospheric volume, since the start of the Cambrian period.
So, form the starting 200 million years ago, oxygen level stay above 15 percent and the correct option is "B".
The answer is B, since the population has no genetic variation it will be classified as an artificial selection not a natural selection.
