Name homologous organs of 3 animals

Hi

Before answering the question, we need to understand what homologous organs are?

These are basically different organs that are found in different animals which apparently look different however they have similar anatomical structure. These are called homologous organs and they are an excellent source that shed the light on evolution of different organisms.

Homologous organs of three animals:

1: Dolphin's flipper

2: A bird's wing

3: Human arm

Although these are three different organs of three different organisms but still they are homologous organs, this is because the anatomical features of these structures suggest that these have similar sort of arrangement of bones, and wing sub parts. This suggests that in past, all these three organisms have a common ancestor and later due to evolution, they evolved into new creatures.

Hope it helps!

step 1 ammonium can be absorbed by plants, but some is converted into nitrates which are better for plants to absorb. this is called nitrification. 2. step 2 the deer eats the plants and uses the nitrogen-containing proteins for cell growth. 3. step 3 bacteria in the soil conduct nitrogen fixation to convert nitrogen gas from the atmosphere into ammonium. 4. step 4 some of the nitrates are absorbed back into plants, but denitrification breaks down the nitrates into nitrogen gas released back into the atmosphere. 5. step 5 nitrogen is found in the urine, which gets broken down into ammonium through the process of ammonification. 6. step 6 plants absorb the ammonium and begin assimilation, the process to add the nitrogen to protein.
