Answer:
Charles Darwin spent almost 5 years in the voyage name HMS Beagle. This voyage made him famous as after returning, he formulated the "Theory of natural selection" as he was amazed by the geographical distribution of the wildlife and also collected fossils that helped him to formulate his theory.
Explanation:
Charles Darwin was the main contributor to the theory of evolution. Besides, he was a geologist, naturalist, and biologist. He first demonstrated the branching pattern of evolution on the basis of natural selection. 18 February 1809 was his birth date and he died in 1882. He explained the theory of natural selection with the help of finches residing in the Galapagos island. The change in the beak structure of the finches according to the availability of food illustrates the process of natural selection and hence the process of evolution.
This statement is true.
Reason:
Plants are capable of storing energy from the sun and with the help of that they produce their own food. And this energy is transformed to the animals as well as human being when they consume the food which was grown on the plants. But when they consume it they are only able to get 10% of the energy and the last consumers are able to get only about 1% of the energy.

This is generally true. It is also combined with the fact that the patients request the usage of the equipment themselves and pay for it. This equipment is definitely great for avoiding malpractice lawsuits.
Answer:
A neuron receives stimuli consisting of the response of thousands of neurons. Synapse is the signals entering the neuron via junctions called. The role of the synapses are to modulate the signal strength and determine the input signal is either excitatory, promoting the neuron to fire, or inhibitory, tending to prevent the neuron from firing.
At the axon hillock the neuron integrates the inputs and if this total is excitatory then the neuron fires. Although this brief description leaves out much of the complexity, it is still remarkable that out of this web of electrochemical firing units, emerges our very conscious.
