Answer: The correct answer is (B) One population of lizards leads to 15 separate species over a short time.

Adaptive radiation is a process of macro-evolution in which one specific life form is rapidly diversified into another new life forms when it encounters changing environmental conditions.    

Thus, when one population of lizard leads to 15 separate species over a short time, it reflects adaptive radiation.      

Example- Darwin's finches on galapagos island, which were adapted for different feeding behavior is the example of Adaptive radiation.

Which outcome is most likely if a nonnative species is introduced to an ecosystem
12345 [234]
Alright! <span>In most cases it will induce nutrition or sth. like that to the ecosystem because it's simply going to be eaten or die or whatever. Just a large amount of animals will be able to survive. They need to be lucky enough to stand the environment (temperature & stuff) and they need to be able to find food and water sources.
In this rare case (I heard it's less than 10%) it might have the luck to have no natural foes so it can spread. The fact that they might not have any natural foes might cause a strong reduction of their food source. So if you have a big ape that keeps on eating dodos and its population keeps on growing and there's nothing that stops it... then one day there will be no dodos left. You see, an alien species usually will not be specialized on one prey, (or food source) because if they were so specialized, they'd be specialized on a food source that you can find at their homes and not at their new environment. (so they would have died out in advance already). So they're likely to survive a little longer.

You have the cats and camels in Australia for example... there are huge masses of them and there are no real natural enemies to "stop" them.

You see, in the usual case there will always be a balance.
Imagine a fox only eats rabits... once there are no rabbits left, the population of foxes will shrink because there's almost no food. Population of rabbits will grow again which makes it possible for foxes to find food easily which will increase their population and as a consequence decrease the population of rabbits ;)
So in the end it is still possible that a balance will be established... but in the worst case it might just create an irreversable unbalance. And... it has usually never been a good idea to invent another species as a natural foe of the other one.</span>

Thr route which convey impulses for sending, pain, temperature, touch and deep pressure are
anyanavicka [17]

Answer

The nervous system has many more sensory fibers and sensory pathways than motor fibers. This stems from the importance of properly understanding the environment prior to responding. These ascending tracts provide the bridge between the inputs from the environment and the organizing centers of the brain that provide the complexity of our responses. Somatosensory systems include the receptors and pathways for transmission of sensory information from the soma to the portions of the brain that need to integrate it and act upon it. While much of this is conscious, there are also ascending systems that convey unconscious information involved in coordination (proprioception) and brain stem reflexes.

There are several different modalities that fall under the broad topic of "exteroception". These sensations include well-localized touch 2-point discrimination), light touch, pain, temperature and vibration sense. These sensations can be tested clinically. Proprioception is the ability to detect the position of the body in space. This may be consciously perceived, such as with joint position sense, or it may be a sensation that is not perceived consciously, such as from muscles and ligaments.

Conscious sensation

We will first discuss the pathways for conscious perception before considering unconscious sensation. These pathways for conscious somatic sensation, at their simplest, require three neurons (and two relay sites) from the periphery all the way to termination the cerebral cortex. These steps are often described as first, second and third order neurons in the sensory pathway. The signal can be modified at each of the relay points (nuclei).

Does the thickness of the wire affect the power of the circuit?
masya89 [10]
I'd say it depends on if were talking about the actual wire or the rubber coating around it the thicker it gets the more strain and power the generator has to put into the wire so i'd say yes the thickness does affect the power but im not an expert
