The answer is a half-filled circle. 
In the pedigree charts, squares present males and circles present females. If a female is healthy, the circle is empty (white). If a female is affected with a trait, the circle is filled-in (usually black). However, if a female is a carrier of a disease, which means that one allele is dominant and one is recessive, then the circle is half-filled.

Hydrogen is similar to electricity. Although an electric vehicle, for an example, doesn't create any tail pipe emissions from the vehicle, that may not be the case where the electricity was made. If the electricity was made from an old, smoking, worn out gasoline powered generator in order to charge the electric vehicle, the total pollution created would be much more than that made by a regular gasoline car. However, if the electricity is made by an environmentally friendly renewable source, such as solar or wind, then the total pollution created in powering the electric vehicle would be much less, perhaps even zero. 
<span>Hydrogen can be made from electricity or petroleum. If made from petroleum it wouldn't be much different than gasoline because the rest of the petroleum would have to be used somewhere. If the hydrogen is made from electricity then the question again is where is the electricity being made. </span>
<span>Your question is also a good one because it highlights the "high use" of renewable energy. The production and use of hydrogen in less efficient than running just off of electricity. So you'd have to produce a whole lot more electricity to make hydrogen to drive a car a certain distance than to charge a battery-electric car and drive the same distanc</span>
        
             
        
        
        
Answer:
Habituation.
Explanation:
Learning may be defined as the process of change in the behavior of the organism by the result of its experience. Two main types of learning are innate learning and acquired learning. 
Habituation may be defined as a type of the non associative learning in which the innate stimulus may get decrease after its repetition. The response of the new born can against the visual memory can be created by taking some picture as stimulus and repeat this stimulus again and again. 
Thus, the answer is habituation.
