Georgio is jogging barefoot along the beach when he suddenly steps on the sharp edge of a broken shell. He instantly feels pain due to the message carried to his brain by<u> dendrites.</u> He then slowly walks home with an achy foot. The message of the ache is carried by <u>neurons.</u>

The nervous system has electrical cells that are trained to transmit and receive messages. Through the use of electricity, people can communicate by transmitting messages to one another. This voltage is produced in neurons by the movement of charged ions. salt atoms with positive or negative charges that pass through the cell membranes and cross the cell's outer membrane. The neuron has dendrites, which are branches (like a tree) that receive messages, and an axon, which is a longer, more straightforward projection (like a tree trunk), that sends information. Synapses. Axon ends include the neuron communication junction, where vesicle fusion releases chemical signals. Neurotransmitters are the chemical messages that the nerve cell releases.

Not TOO sure here, buuuut I’m pretty sure it’s TRUE because a state is much more complex then a whole country, and therefore has a lot more constitutions.
<span>Genetic mutations may impact more than one system in the body because the causes for the mutations may be present in more than one system. For example, a person may take a genotoxic or teratogenic medication, which could then be carried throughout the body in the bloodstream.</span>
I believe the punnet square is showing the genotypes of the F2 generation. If that is true, the answer would be 3 red : 1 white. This is because the four genotypes are RR, Rr, Rr, and rr. Out of those, 3 contain the dominant allele R that codes for red, while only one contains both recessive alleles that code for white. Hope this helps!
