When considering whether structures from two kinds are homologous, look for similarities in structure, function, and evolutionary history. Homologous structures are found in different species but have a common ancestor, so they may have different functions but share a common structural design due to shared ancestry. Evolutionary relationships, embryonic development, and genetic similarities can also provide evidence for homology.
because there are many kinds of atoms that form even more kinds of molecules that result in even more structures. It is like how an entire language is made up entirely of so many letters
Ribosomes are found in both prokaryotic and eukaryotic cells. They are the cellular structures responsible for protein synthesis.
The four kinds of specialized leaves that compose a flower are sepals, petals, stamens, and carpels. Sepals are usually green and protect the developing flower bud. Petals are typically colorful and attract pollinators. Stamens are the male reproductive structures that produce pollen, while carpels are the female reproductive structures that contain the ovules.
