Much like a cell, a virus is able to grow and reproduce in large numbers
A virus is a microscopic nonliving parasite that only reproduces inside the cells of living hosts. Like cells, viruses have the ability to grow and reproduce within the host cell. When a virus infects a host cell, it injects its genetic material into the cell and forces the host cell to produce thousands of similar copies of the original virus.
Calories from saturated fats and/or added sugars in foods that have little or no nutritional value, such as sausages and ice cream, are called Empty Calories.
Calories can be defined as the amount of energy extracted from the food which an individual eats throughout the day. According to dietary guidelines, a young person [20-25 years old] must intake between 1,600 and 3,000 calories per day.
Foods such as sausages, ice cream, pizza, and soft drinks have a high amount of empty calories because solid fats and added sugars are used in their manufacturing to add flavors and make the food more appealing but they have no nutritional value.
The amount of empty calories a person intakes should be decreased by avoiding such food items and drinks.
