Answer:
Temperatures gradient
Explanation:
There are distinct temperature gradient differences in the layers of atmosphere usually due to the main air molecule composition of the layers, the density of the molecules. The Troposphere the lowest layers is the densest and temperature decreases with increase in altitude. The stratosphere, on the other hand, has an increase in temperature with increase in altitude. Temperatures decrease with altitude in the mesosphere while the parameter increases with altitude in the thermosphere.
Answer:
A. They have the same function
B. They have evolved independently
C. They indicate an evolutionary relationship
Explanation:
- Analogous structures are structures with a different embryonic but have evolved to perform similar function.
- <em><u>Analogous structures are a result of convergent evolution which is the independent evolution of similar features in species of different lineages or different embryonic origin.</u></em>
- Examples of analogous structures include; wings in flying animals like bats, birds, and insects, and fins in animals like penguins and fish.
