hemoglobin is a protein that binds to oxygen. it is only produced by red blood cells and it allows blood to transport oxygen throughout the body
what statement does this information best demonstrate?
a.
the proteins produced by cells have structures that are related to their function
proteins in specialized cells are the result of the expression of particular genes
c.
specialized cells that are grouped together and perform similar functions are called tissues.
d.
proteins with similar functions to those produced in humans can be found in other species

A. The proteins produced by cells have structures that are related to their function

Explanation:

The primary functions of red blood cells are: to transport oxygen from the lungs to the tissues, maintaining adequate tissue perfusion, and transporting CO2 from the tissues to the lungs. Hemoglobin, which makes up 95% of the proteins in red blood cells, is responsible for these functions, that is, Hemoglobin is a protein that is present in the bloodstream that performs the transport of oxygen from the lungs to the cells of the body and also bring carbon dioxide into the lungs, where it will be expelled. This protein is responsible for the reddish color of our blood, it is indicative of a healthy or anemic organism.

As shown, the relationship between protein and hemoglobin is very intimate. This is because the proteins produced by cells have structures related to their function.

not sure but try c two haploid cells
