If the isthmus formed gradually rather than suddenly, the morphological species, biological species, and phylogenetic species concepts.
<h3>
What is Isthmus genetical species?</h3>
The formation of the Isthmus of Panama, a slender land bridge that connects North and South America, caused the Pacific and Caribbean populations of marine organisms to split off about 3 million years ago. On both sides of the isthmus, different species of snapping shrimp have been studied. There appeared to be seven pairs of species, with one species of each pair being found in the Pacific and the other in the Caribbean, according to the morphological species concept.
The various species pairs inhabit slightly different ocean depths. These species pairs, which are divided by the isthmus, were indeed the closest relatives of one another, according to the researchers' estimates of phylogenies based on mitochondrial DNA sequences.

Answer: Friction slows down the swing of the pendulum until it fully stops.
I'm not sure what to put for the next question
After miles of running and sprinting in intervals, the runner's muscle ache and feel fatigue due to anaerobic respiration taken place in the muscle cells.Anaerobic respiration in animal cell gives Carbon Dioxide and lactic acid as products. Due to the formation of lactic acid after running, muscles feel fatigue and ache.
I hope I helped you! ^^
I guess it is euglena because, i<span>t's a plant like protist, it contains chlorophyll and carries out photosynthesis. The eyespots function as a light shield which allows light from a certain direction to strike the light detector.
it doesn' have a cell wall because it is "plant-like," not a plant,
it has a pellicle that provides strength and flexibility since it lacks a cell wall</span>
Broad niche because it will be able to adapt and have a different niche under the same category
Hope I helped!
