Respuesta:
d. Ninguno tiene la razón
Explicación:
Para convertir masa a moles, necesitamos la masa molar de cada sustancia.
Fernando (58.85 g Fe)
La masa molar de Fe es 55.85 g/mol.
58.85 g × 1 mol/55.85 g = 1.054 mol
Jacqueline (23.05 g Na)
La masa molar de Na es 22.99 g/mol.
23.05 g × 1 mol/22.99 g = 1.003 mol
Carlos (35.45 g Cl)
La masa molar de Cl es 35.45 g/mol.
35.45 g × 1 mol/35.45 g = 1.000 mol
Paola (27.0 g Al)
La masa molar de Al es 26.98 g/mol.
27.0 g × 1 mol/26.98 g = 1.00 mol
Answer:
The correct answer is biological.
Explanation:
When any pathogen invades the body, it has to pass several lines of defence. The first barrier is the skin and mucous membrane which is a physical and chemical barrier. The second line of defence is the non-specific response by macrophages, neutrophils and interferon. After crossing these two barriers the third line of defence comes into action in which, the B- cells and T-cells act specifically on the pathogen and destroy it.
