Answer:
The completed sentences are given below.
Explanation:
Haemoglobin is a complex protein consists of heme and globin. Heme contains iron as central element.
The prosthetic group of hemoglobin and myoglobin is heme.
The organic ring component of heme is porphyrin.
Under normal conditions, the central atom of heme is Fe²⁺.
In deoxyhemoglobin the central iron atom is displaced 0.4 A out of the plane of the porphyrin ring system.
The central iron atom has 6 bonds: 4 to nitrogen atoms in the porphyrin, one to a histidine residue and one to oxygen
One statement that could disprove this theory is the fact that, according to the cell theory, all cells come from pre-existing cells. This basically means that cells can't just appear from nowhere; they have to come from another cell. Based on what we know today from scientific research, is there another law or statement that you could come up with to help disprove the theory? Hope this helped! :)
The atoms are going through decomposition.They are breaking apart into the elements they are made of.
<span>If I were attempting to date a rock sample that I suspect to be incredibly old, i would use radioactive isotopes with a long half life. When dating rocks and fossils to discover approximately how old they are, radioisotope dating is used on igneous rocks found near fossils. Things like Uranium 235, which is an unstable radioactive isotope of elements, decays at a constant rate over time so can be useful in determining age.</span>
