The ecosystem that he should consider is the <span>tropical rain forest ecosystem.
In that area, there are uncountable amounts of various plants and animals that have not all yet been discovered and who all live together to build the biome. This biome is indeed the most diverse one even at this point without the knowledge of all possible life forms.</span>
Answer:
The beginning of Cambrian period was about 541 million years ago and ends about 484.5 million years ago.
Explanation:
Cambrian period is a geographical period that appears in Paleozoic Era and lasts at Phanerozoic Eon to the beginning of Ordovician Period and the name was given as most of the sedimentary deposits were found at that period The majority of living organism includes unicellular or some multi cellular complex life forms.
Most live forms were aquatic and arthropods were the most dominant animals in the water that are known by studying the fossil records.The species adapt themselves to change with the environmental variations.
Animals like <em>Protichnites</em> and <em>Climactichnites</em> were found during this period.
The fossil records also suggested the presence of euthycarcinoides that are the extinct arthropod species.
I believe the answer is echinodermataechinodermata and Chordata have a very similar embryonic development; tirhe first opening (the blastopore) becomes the anus, while in protostomes it becomes the mouth and several similarties in the formation of skeleton.It is predicted that Echinodermata and Chordata evolved from the same ancestor
Answer: It Should Be True
A neuron is nerve cells that transfer information within the body, chemically over short distances, using electrical signals over long ones.
As it turns out, most resting neurons are permeable to Na+ and CL- as well as K+. K+ will try to drag the membrane potential toward its (positive) equilibrium potential, while NA+ try to drag the membrane potential to its negative equilibrium potential.
The real membrane potential will be between NA+ and K+ of equilibrium potential<span>. However, it will be closer to the equilibrium potential of the ion type with higher permeability.</span>
