Hemoglobin is the protein that transports oxygen in mammals. Hemoglobin is 0.347% by mass, and each hemoglobin molecule contains four iron atoms. Calculate the molar mass of hemoglobin.

Molar mass of hemoglobin is 64380.4 g/mol

Explanation:

Percentage of Fe calculated from the equation

%Fe   =  4×molar mass of Fe/molar mass of hemoglobin.(4 because hemoglobin contain 4 Fe atoms)

Molar mass of hemoglobin is =4×molar mass of Fe / % Fe

                                                 =4×55.85/.00347

                                                 =64380.4 g/mol.

correct answer: understand the different control methods available

integrated pest management is an strategy that is based on the ecosystem and try to prevent the pest and the damage caused by them by applying combination of technique like habitat manipulation, biological control and use of resistant varieties.

the main aim of the integrated pest management is not to completely eliminate the pest but to strengthen the ecosystem so that conditions are favorable for plants and unfavorable for pests.

the principles and empirical processes of discovery and demonstration considered characteristic of or necessary for scientific investigation, generally involving the observation of phenomena, the formulation of a hypothesis concerning the phenomena, experimentation to test the hypothesis, and development of a conclusion that confirms, rejects, or modifies the hypothesis.
