Explanation:
Actually the haemoglobin molecule consists of 2 parts, the haem which is a prosthetic group and the other globin which is a protein. So the haemoglobin as is a protein so, is arranged in quaternary structure of protein which contains 4 subunits. The subunits depend upon the organism whose haemoglobin is being talked about. So the normal haemoglobin found in red blood cells contains 2 alpha subunits + 2 beta subunits. At the centre of each subunit there is the haem part attached. To the centre of haem the Fe3+ ion are present which actually attaches to 1 Oxygen molecule. So as 4 subunits are present and each subunit has 1 Fe3+ ion, so total 4 Oxygen molecules can bind to the 1 Hb molecule!!
Answer:
Option A. magnitude
Explanation:
Electric field is the area around the electric current where its effect is observed. If the lines of electric field are close to each other, it means electric field is stronger and if the lines are far away from each other so it indicates that the electric field is weak. There is inverse relationship between electric field and distance from the charge. If the distance is higher, so the electric field is weak and vice versa.

Explanation:
Unclear question. However, I inferred you are referring to this clear rendering of the question:
Determine the degree of pollution with household waste in your neighborhood or your locality:
1. List the human and administrative (social) causes that led to such a situation.
2. What actions must be taken to solve the given problem?
3. What should be your contribution in solving the problem of environmental pollution?
4. Write an essay on the topic: "My community - the beneficial space for work."
