Answer:
The correct answer is "some stickleback populations come to live exclusively in fresh water they became trapped in lakes that formed at the end of the last ice age".
Explanation:
There are different types of speciation. Allopatric speciation consists of the geographic separation of a continuous genetic background so that it can give place to two or more new geographically isolated populations. Some barriers might impede the genetic interchange or genetic flux, making a place to two new populations that are separated and can not get together to mate anymore. Glaciation is one of the most important drivers of speciation and production of different phylogeographic structures by vicariance. Glacials originate isolated gene-pools that accumulate differences that end in reproductive isolation. Melting of the ice also generated divergence and speciation, as land appearance acted as a barrier for some populations.
During the last glaciation, stickleback fishes were able to reach certain new places or areas that provided better conditions to inhabit. There were fewer predators and more available food sources that made these new areas to be a better choice. These new grounds were lakes and were the product of ice melting. But at a certain point, as ice melting increased, the land started to show up again and became a barrier for this species. Animals that were living in lakes could not go back to the sea, they were trapped so they had to adapt to living exclusively in lakes. This species diverged and suffered speciation.
Answer:
3 molecules of water and use glycerol and fatty acid reactants
Answer:
The correct answer is: trilobite.
Explanation:
<u>Trilobites</u><u> were the most common form of early sea life found in Oklahoma</u>. Trilobites were arthropods that are now extinct. This marine species is thought to have lived during the early Cambrian period and they existed for almost 300 million years, before disappearing at the end of the Permian in the Permian-Triassic extinction event.
Dolomite is a sedimentary carbonate rock that is rich in calcium.
Bryozoans are a species of seaweed-like aquatic invertebrate animals that have lived since the early Ordovician period.
The Apatosaurus was a herbivore dinosaur that lived in North America during the Jurassic period. They had very long necks and were related to the Brontosaurus.
the students claim is incorrect, this is because plant's don't have pain receptors, so for example,if an animal were to eat a strawberry, the plant would not be harmed, nor would the plant be harmed if a leaf or bud was removed, it would simply develop new growth. And the plants survival actually increases because most animals will eat the seed with the fruit, and when animals defecate , the seeds have a natural fertilizer.
hope this helps, if it doesn't pls tell me what you think I should change!
