5 0

Explanation:

In reference to evolution, homology can be described as the comparative similarities in the structures of organisms that make it more alike to one organism than the other organisms. It also shows the characteristics that might have evolved in an organism over time. Developmental homology are the similarities which arise between organisms due to similar embryological source.

Developmental studies can be made by researching the embryological developments of different organisms and looking for similarities among them.

For example, studying the snake embryos showed that some of the embryos have hind limb buds in them which disappeared in the mature snake. This study made it clear that snakes evolved from organisms that had hind limbs. As the snakes do not need the limbs, so with time the species of snakes evolved and lost their hind limbs.

What would happen to co2 if there was less plants
MArishka [77]

Answer:

More carbon dioxide (CO2) would be in our atmosphere.

Explanation:

Plants undergoing photosynthesis take in carbon dioxide (CO2) and give out oxygen (O2). They essentially use the CO2 to make sugars that keep them alive. Excess plant CO2 is then given off back into the environment, just like how we exhale CO2 after taking a breath.

So, no plants to take in the CO2 equals more CO2 in the environment.

Think of it kinda like this: I like Pop Tarts. If there is less or none of me in the world, there are more Pop Tarts just... out there... waiting to be eaten.
