Explanation:
Leukemia begins in the immature of the developing cells of bone marrow. Bone marrow produces different types of blood cells: red blood cells that carry oxygen and other materials to the tissues of the body; white blood cells that fight infection; and platates that fight that help the blood clots grow. In all, the bone marrow produces an excessive amount of ABNORMAL white blood cells, which don't function properly and cause effects to a person's body dealing with leukemia.
 
        
             
        
        
        
Answer:
UCS: sticks part of the toy into the electrical outlet
UCR: frightened and crying
CS: toy
CR: frightened to toy
Explanation:
Classical conditioning is a form of learning whereby a conditioned stimulus becomes associated with an unrelated unconditioned stimulus, in order to produce a behavioral response known as a conditioned response.
<u>Unconditioned stimulus</u> (UCS) is an agent that leads to a response without training. In this example, the child won't know that he can have electrical shock playing with toys.
<u>Unconditioned response</u> (UCR) is an automatic response to a UCS that's why the child starts crying and frightened.
<u>Conditioned stimulus</u> (CS) is a former natural stimulus that comes to elicit a given response after pairing with a UCS. In this situation, CS is when mom gives the same toys to the baby that was the reason for electrical shock.
<u>Conditioned response</u> (CR) is a learned response to a CS because the baby shows fear when he saw the same toys. It is his learned behavior.
 
        
                    
             
        
        
        
Answer:
Explanation: 
El impulso nervioso es un impulso eléctrico. Para que el impulso eléctrico se transmita, los iones positivos de sodio que están en estado de reposo y están presentes fuera de la neurona deben traspasar la membrana celular. En la medida que el impulso avanza por la membrana, su interior recobra la carga negativa. 
 
        
             
        
        
        
Stimulus stimulate the sodium ion voltage gated channel to open in the axon. This allow many Na ion to enter the axon and causes depolarisation as the pd in the axon getting less negative charge (from -70mV to -50mV).
