Exercise is the primary advice the coaches give to the athletes if they get a cold or any other infection. The main reason behind this advice is the fact that exercising strengthens the immunity of a person. When a person has an infection, the strengthening of the immune system will help his body to efficiently fight against the infectious pathogens. The blood circulation is increased which is involved in the enhancement of the acute immunity of the person.
Answer: we classify organisms to group living beings who share the same characteristics or who have common attributes
Explanation: So, since the late '60s and based on the proposal of the researcher Robert Whittaker, most biologists group living beings into 5 large groups called Kingdoms, based mainly on three characteristics:
* type of cell,
* number of cells in each organism and
* the way of obtaining energy.
As a result, we could have 5 kingdoms; and these kingdoms are:
Monera, represented by the microorganisms of prokaryotic type known colloquially as "bacteria"
-Fungi, represented by mushrooms
-Plantae, the kingdom of the plants
-Animalia, the kingdom of the animals, and
-Protist, a very diverse group of organisms of eukaryotic type.
