The answer would be appropriately shaped receptors
When blood is in the lungs,
where oxygen is plentiful, oxygen easily binds to the first subunit and then quickly fills up the remaining ones. Then, as blood circulates through the body, the oxygen level drops while that of carbon dioxide increases. In this environment, hemoglobin releases its bound oxygen.
The majority of photosynthesis occurs in the chloroplasts.
The first two blanks are evidence of climate change, third blank is the main cause of climate change, and the fourth blank is a mechanism by which climate change occurs.
The scientist will add up the mass of the protons and mass
of the neutrons to come up with the approximate mass of atom because protons
and neutrons is what consist of the atoms. Therefore, in order to have the approximate
mass of an atom, adding the mass of protons and neutrons will give the result.
