Our body needs all 5 nutrients - protein, carbohydrate, fat, vitamins and minerals. However, protein is the nutrient is needed for proper growth and development. Correct answer: C
Proteins are needed to build, maintain and repair muscle, blood, skin and bones and other tissues and organs in the body. The main sources of animal proteins are milk, fish, meat, cheese and eggs. Large amount of protein is needed for building new tissue in short period, such as during infancy, pregnancy or when mother is nourishing a child.
A balance of all the nutrients in diet is essential but the nutrient that is important for growth and development is protein. The correct answer is option c.
There are in all five nutrients proteins, fats, carbohydrates, vitamins and minerals. Sometimes water is included as the sixth nutrient. A balance of all is important for proper functioning of the human body.
Proteins are very important in human physiology, they act as structural elements within the cell such as actin, form the extracellular matrix (ECM) elements, act as signaling molecules, hormones etc.
As the growth occurs repairs and maintenance is required and this work is carried out by proteins. With growth an additional need for protein is created which is why it has to be taken externally through diet.
It is helpful to remember the central dogma, and remember that in execution the blueprint of our growth and development (DNA) is carried out by the formation of proteins.
Growth and development requires formation of new structures and completion of processes, a lot of which are undertaken by proteins. From structural elements actin, tubulin, enzymes such as hexokinase, lysozyme, to chaperones that help folding of other proteins, proteins play an important role in growth and development.
For growth and development protein is required. Correct option is c.

B. appetite.
C. culture.
D. activity level.
The amount of energy a person can consume throughout the day without gaining weight is extremely dependent on activity level. Correct answer: D
Our bodies need energy (calories) which we get from food in order to perform on normal everyday processes like breathing and pumping blood, and this is referred to as the basal metabolic rate ( about 1,300-1,500 kcal/day for an adult female and 1,600-1,800 kcal/day for an adult male). However, the body needs energy also for physical activity. The more active the more calories are needed. This is the reason why athletes need far more calories during the day than the other people.
