What are developmental homologies, and how are they studied?
7nadin3 [17]

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.

7. What causes greenhouse gasses to absorb heat when gasses like oxygen do not?
Scilla [17]

Answer:

Hope the below helps!

Explanation:

Greenhouse gases (such as methane, carbon dioxide etc) have lots of vibrating particles. These molecules eventually release radiation, which travels up Earth's atmosphere (because warm air rises), is trapped and adds to the greenhouse gas effect.

Oxygen and nitrogen don't interfere with infrared waves in the atmosphere. That's because molecules are picky about the range of wavelengths that they interact with.

I have attached a diagram that shows the greenhouse effect. It might help to visualise this.

Foreign invaders have proteins called _____, which antibodies lock onto to neutralize.
stich3 [128]
Foreign invaders have proteins called antigen, which antibodies lock onto to neutralize. The foreign proteins are different from proteins in our own body, so the immune system can recognize them and finally eliminate them.
