If the pedigree you are referring to is the one that is attached then the answer would be:
A pedigree shows how a trait is passed on throughout generations. Like it says in the question, the squares represent males. If the square isn't shaded in, then that means they are unaffected by the trait or normal. If it is shaded, they are affected.
All you need to do for the first question is count the number of squares you see in the whole pedigree. In this case, there are 8.
The second one is asking how many are affected, or have hemophilia. You need to count the number of squares that are shaded in. In the pedigree, we see 3.
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.
