I'd say more effective.
"Insects have a more efficient respiratory system than humans. "
But at the same time insects don't have any lungs they breathe through the help of trachea/tubes/and or holes along their abdomen area.
You need to think about how small, compared to us humans, and insect is. They can take in a lot more oxygen than we can (for their size)
If we were to be able to shrink until we're the same size as an insect, they would be the ones taking in way more oxygen because of the way their system is constructed.
Explanation:
the rate of weathering is not the same for all rocks. Factors such as surface area, rock composition, and location influence the rate of weathering. water, the faster the rock will break down. A greater surface area allows chemical weathering to affect more of a rock.

Explanation:
Answer:
20 million years
Explanation:
If we have a neutral mutation rate of one mutation per 5 million years, then the total of eight mutation between the two different species would be 20 million years. This is because both species will have 4 mutations in those 20 million years, so combined, both by 4, will have 8 mutations between them. So few mutations on so much time will result in two species that are very similar to each other even after 20 million years of evolution, even making them hardly distinguishable, especially if it comes to defining fossil records from them both. A nice example of this are the members of the felidae (cat) family, which are all very closely related, and are almost identical, thus making it extremely hard to distinguish two species of the same or similar size by their fossils.
