those are nucleotides 
since all three of them contain deoxyribose (because there's only one hydroxil group) they are DNA nucleotides
the first nucleotide has cytosine as it's nitrogenous base 
the second nucleotide has adenine as it's nitrogenous base 
the third nucleotide has thymine as it's nitrogenous base
 
        
             
        
        
        
Answer:
1) Hunger, savor, appetite. Three main biological reasons why we eat. Also, the economic ability to pay for the food. And the fisical capability to go and buy food, to cook.
2) Our physiological needs are the main reason why we choose food. People need energy to survive.
Everyone would like to have the possibility to eat what he wants. But food choices depend on the financial situation, social class, and preferences. 
That is why poor people or people who have less money to spend on food, often eat food that can feed more people but it doesn’t have nutritional values. When people have money, they immediately have a wider spectrum of groceries that can choose from.
Explanation:
Savour is equal to enjoying. When people are not hungry they are happier. We choose what to eat depending on the look, taste, smell, texture. As sweets smell good, people consider them the most attractive food. Food is not just the source of nutrition, it is also the source of satisfaction.
 
        
             
        
        
        
Answer:

Explanation:
Most of the fungal species reproduce through spores. Spores are the reproductive structures of fungi that help in the survival of fungal species under unfavorable conditions and their dispersal to new habitats. Fungal spores are very light in weight and are dispersed with wind currents. 
For example, ascospores are the sexual spores produced by fungal species of the group ascomycetes and are carried with the wind.
