Answer:
The correct option is A) Many of the younger married couples in Italy are deciding to have less children.
Explanation:
As we know the birth rate of a country should be equal to the death rate of the country in order to maintain a stable economy. In the past, people were not concerned about the rising population and hence did not look upon child birth rate. But nowadays, the younger population is more concerned about the rising population and hence tends to take more steps to control the population. 
 
        
             
        
        
        
<span>Parents can pass on chromosomes to their children that are different than their own when the new gene combinations are created by crossing over. The exchange of genetic material between homologous chromosomes is known as crossing over which occurs in meiosis. When homologous chromosomes pair up and exchange different segments of the genetic material. As the result, a new combination of genes will be formed. If there was not crossing over, all genes on a chromosome would be inherited together.</span>
        
                    
             
        
        
        
<u>Answer</u>:
The distinction between the sensation and perception allows the researchers to distinguish between the information processed by the receptors versus the information processed in the cortex. 
<u>Explanation</u>:
The sensation is a process by which the sensory receptors take up the signals or stimuli from its surroundings and send it to the brain through nerves. Whereas, in the process of perception the brain organizes, combines and makes patterns from the given stimuli and gives the response to the particular stimuli accordingly. 
Both sensation and perception are connected to each other hence if one doesn’t work then the other automatically stops working.
