Answer:
Soil erosion affects soil health and productivity by removing the highly fertile topsoil and exposing the remaining soil. It decreases agricultural productivity, degrades ecosystem functions and amplifies hydrogeological risk, such as landslides or floods
Explanation:
The question is incorrect. The correct question is as follows:
The prosthetic group of hemoglobin and myoglobin is _______?
The organic ring component of heme is _______?
Under normal conditions, the central atom of heme is ________?
In ________ the central iron atom is displaced 0.4 A out of the plane of the porphyrin ring system.
The central iron atom has _______ bonds: ________ to nitrogen atoms in the porphyrin, one to a _______ residue and one to oxygen.
Answer:
The hemoglobin is an important protein that transport oxygen in the body and contains the pigment that gives the red color to the red blood cells. The myoglobin protein is responsible for transport of oxygen in muscles.
The heme molecule acts as prosthetic group for both myoglobin and hemoglobin. The porphyrin ring is present in heme molecule. The iron molecule especially Fe2+ is present in heme molecule. The deoxyhemoglbin states occur when the central atom is displaced 0.4 Å. The iron central atom can form six bonds and forms four bonds with the prophyrin of nitrogen and one bond with histidine molecule. Histidine acts as a buffer fir the blood.

So, a sudden drop in the death rate means that while everything stays the same, less penguins are dying: the penguins are living longer! This means that the population will increase: there will be more penguins at all times!
