Answer:
Food refers to any nutritious substance whereas diet refers to the food eaten by organisms daily.
2,110 calories.
Explanation:
1. Food refers to any nutritious substance that an organisms eat in order to survive and maintain growth whereas diet refers to the sum of food that is consumed by an organism.
2. Malnutrition refers to a condition that occurs from eating a diet which does not supply a healthy amount of nutrients to our body whereas hunger refers to a feeling of discomfort that is caused by lack of food.
3. No, it is not possible to be over-nourished and under-nourished at the same time because a person can attain one condition at a time whether he can be over-nourished or under-nourished.
4. The three elements of food security are availability, access and consumption of food. Availability of food means having sufficient quantities of nutritive food available to a person, access means having sufficient resources to have access to the food and consumption means having taking sufficient amount of nutrients and the ability to absorb and use nutrients in the body. 
5. 2,110 calories are taken by consuming 345g of carbohydrate, 80 g of protein, 45g of fat and 12g of alcohol.
 
        
             
        
        
        
If the uppercase letters represent the dominant alleles, purple flowers and tall are the phenotype of a plant with the genotype Pptt.
A gene can exist in different forms across organisms. These different forms are known as alleles.
The subsequent combination of alleles that an individual possesses for a specific gene is their genotype.  
Examples of  genotype include:
- Hair colour
- Height
- Shoe size
- Eye colour
The sum of an organism’s observable characteristics is their phenotype. A key difference between phenotype and genotype is that, whilst genotype is inherited from an organism’s parents, the phenotype is not.
Whilst a phenotype is influenced the genotype, genotype does not equal phenotype. The phenotype is influenced by the genotype and factors including:
- Epigenetic modifications
- Environmental and lifestyle factors 
Observing the phenotype is simple – we take a look at an organism’s outward features and characteristics, and form conclusions about them. Observing the genotype, however, is a little more complex.
Genotyping is the process by which differences in the genotype of an individual are analyzed using biological assays. The data obtained can then be compared against either a second individual’s sequence, or a database of sequences.
