Answer:
The haemoglobin levels or counts can be used.
Explanation:
The oxygen carrying pigment of the blood is the heamoglobin (Hb).it is a protein molecule with for heam groups,Each of the latter can bind with 4 molecules of oxygen in a cooperate bonding.The more oxygen molecules binding by Hb,the more oxygen is carry in RBC.
Therefore if the number of Hb counts is reduced in an individual the volume of oxygen in the RBC of the subject should reduced,Therefore, this should be a good indicator of the lower oxygen capacity of the blood of the individual.
Basically in a physiological female the Hb count/100ml of blood is 12-16g/ml,like wise 13-18g/100mI in a physiological man.
Therefore fluctuations in the levels of these values below the set points is an indicator of distortion in the oxygen carrying capacity of the blood.
The amount of the blood in volume that contains RBC is called Hematocrit. Therefore for accuracy the HCT together with the Hb counts are good indicators of oxygen capacity of the blood.
I think the answer is C, it’s helps
The answer should be 4) as it is known that uv radiation might have an effect on dna, thus causing mutations such as skin cancer in humans.
Sea floor spreading occurs at divergent plate boundaries where the seafloor is being pulled apart by convection currents in the mantle. As the plate pull apart magma up wells and new crust is being formed. This process on the sea floor creates a habitat for exotic sea creatures such as tube worms. The food chain in this region of the planet starts with bacteria that metabolizes sulfur coming from hydro-thermal vents along the spreading ridge. <span />
