Answer:
On his visit to the Galapagos Islands, Charles Darwin discovered several species of finches that varied from island to island, which helped him to develop his theory of natural selection.
Darwin's finches are a classical example of an adaptive radiation. Their common ancestor arrived on the Galapagos about two million years ago. During the time that has passed the Darwin's finches have evolved into 15 recognized species differing in body size, beak shape, song and feeding behaviour.
Answer:
When a nerve impulse reaches the end of an axon, the axon releases chemicals called neurotransmitters. Neurotransmitters travel across the synapse between the axon and the dendrite of the next neuron.
Explanation:
The binding allows the nerve impulse to travel through the receiving neuron.
<span>Two prokaryotes turning into a eukaryotic cell began with a process called
endosymbiosis. One large prokaryote engulfs (a process called
endocytosis) one small, aerobically respiring prokaryote. The small
prokaryote turned into a membrane-bound organelle, which prokaryotes do
not have, and like we know, only eukaryotes have membrane-bound
organelles. So that is how the eukaryotic cell structure evolved from
prokaryotic cells, meaning that before this evolution, they were most likely symbiotic.</span>
