Answer: The spellings are wrong. It should be globulin and heme.
Globulin alone is not effective as oxygen carrier because globulin does not have oxygen binding groupband cannot bind oxygen.
Heme alone is not effective as oxygen carrier because the iron present in heme can be oxidized easily and it cannot bind to oxygen.
Explanation:
Globulin are proteins that are present in the blood of humans. It is an oxygen carrier.
Heme is iron containining compound that form the non protein part of haemoglobin and other biological molecules. Heme are responsible for carrying oxygen in the blood.
4. A section of DNA that codes for a specific trait.
The earthworm's mouth has the prostomium front tip of the
worm which hangs over. Notice the presence of tiny bristles called setae which
are found on the ventral surface of the earthworm. Another dissimilarity
between the dorsal and ventral surface is the fact that the ventral surface is
lighter in color.
