Answer:
The correct statement about the hemoglobin and myoglobin is as follows:
1. Each hemoglobin molecule can bind four oxygen molecules; each myoglobin can bind only one oxygen molecule.
3. By itself, heme is not a good oxygen carrier. It must be part of a larger protein to prevent oxidation of the iron.
4. Both hemoglobin and myoglobin contain a prosthetic group called heme, which contains a central iron atom.
5. Heme is composed of an organic protoporphyrin component and a metal atom.
6. Each iron atom can form six coordination bonds: One of these bonds is formed between iron and oxygen.

 <span>Mitosis is Asexual reproduction. It promotes genetic consistency because all offspring are exactly identical to the parent, unlike meiosis where homologous chromosomes are randomly dispersed between four daughter cells. organisms that only reproduce asexually are at a disadvantage because all organisms in their population are identical so if there were to be a major environmental change, they would have less of a chance of survival compared to a population of sexually reproducing organisms that are all genetically different.</span>
        
             
        
        
        
Tropism
It is a biological phenomenon, indicating growth or turning movement of a biological organism. This is usually a plant in response to the environmental stimulus. This response is dependent on the direction of the stimulus. The stimulus must be perceived first, followed by movement towards or away to the stimulus. There are various types of tropism which are chemotropism, exotropism, geotropism and electrotropism.
