Answer:
The simulation only shows how a population can change overtime in response to the changes in the environment. During the industrial revolution, one particular phenotype of moths had an advantage over the other and hence, was subjected to natural selection. What this simulation does not tell us is the causality and correlation aspect of the change that occurs in the moths. Correlation does not equal causation, and the simulation does not shed any light on these variables in this case.

Answer:
Yes, the species of a lizard can be identified using dichotomous keys.
Explanation:
A dichotomous key is an identification tool used by the biologists especially taxonomists to identify and classify the organisms.
The dichotomous keys are based on the characteristic feature of an organism for which two which contains two contrasting feature. The dichotomous keys are the most common tools used to classify an organism.
A species of lizard can be identified using these keys by selecting the key characteristic feature shown by the species which could be quantitative like weight, height or it could be qualitative like colour. By comparing these characteristics, it becomes easy to identify the species.

Explanation:
On piercing his foot, the pain receptors called nociceptors, found in the skin, are activated. Nociceptors exist at the nerve endings of the primary afferent neurons. Signals travel along the first order neurons which have cell bodies within the dorsal root ganglia of the spinal cord. In the dorsal root ganglia, the signals are taken up at the synapse with the second order neurons which have cell bodies in the nuclei of the cranial nerves within the brainstem. These neurons ascend cranially in the spinothalamic tract to the thalamus. The third order neurons lie within the ventral posterolateral nucleus of the thalamus. They terminate at the somatosensory cortex where the signals are being processed and returned as a sensation of pain.
