The most famous definition of a species comes from the 20th century German-born biologist Ernst Mayr, who emphasised the importance of interbreeding.
Answer:
Nervous: carries messages
muscular: moves the body
epithelium: found in cartilage
connective: found in cartilage
Explanation:
Answer:
Evolution in humans is happening spontaneously and the development of species can improve the capability of offspring and the intelligence of species. All animals today are evolutionary, we came from bacteria to being are millions of times the size of that organism with millions of years going through evolution. We have gone from splitting our cells to make more, to creating life to another to do the same.

Answer:
You didn't give options to choose from so I'll just wing it.
Over-predation will most likely be the cause of the extinction of the butterflies
Explanation:
Since the birds are preying on them, their population will most likely go extinct because of the birds.
Answer:
"Some organelles contain their own DNA that is more similar to prokaryotic DNA in structure and function than to the eukaryotic DNA found in the cells' nucleus."
Explanation:
- <u>Endosymbiotic Theory:</u>
According to the endosymbiotic theory many prokaryotic cells came closer and formed a much complex cellular structure, which was then termed as a eukaryotic cell. Before, the formation of the eukaryotic cells there were free floating organelles which after evolution came closer and formed the eukaryotic cell in general.
<u>For example:</u>The Mitochondria and plastids inside the plant cells, were first free floating but then they formed a symbiosis and gave rise to a more complex cellular structure called as the eukaryotic cell.
A botanist who carried out the analysis of determining the possibility that eukaryotes cells evolved from the prokaryotic cells,due the change inside the cellular body formation occurred some million of years before. Which turned everything into a form of symbiotic relationship with one another. The organelles which were first free now are in symbiosis with another.
- As he analysed the plastids and the mitochondria(which is the power house of the cell). They had some DNA or genetic material stands which looked more similar to that of that the prokaryotic cells DNA.So, it made it very clear that once these cell organelles were free living, as they had there genetics material to flow from one cell into another. And now the organelles are in the symbiotic association with another inside a eukaryotic cell.
