Most health experts recommend eating tuna a few times a week and eating shark few times a month because: eating these fish could result in the buildup of pollutants in fat tissue of humans.
<h3>Why health experts recommend tuna and shark to be consumed less?</h3>
Large fish like sharks and tuna feed on smaller fish and can accumulate high levels of environmental pollutants like mercury and the risk also increases as off-shore pollution increases.
Shark meat is recommended only a few times a month because sharks are apex predators who accumulate high levels of toxic chemicals and heavy metals from both skin absorption and from consuming prey. This is called bioaccumulation.

Answer:
The correct answer is a. greater than
Explanation:
The partial pressure of oxygen in alveolus is greater than partial pressure of oxygen in deoxygenated blood in a pulmonary capillary and this concentration difference is important for the movement of air(oxygen) from the alveolus to the pulmonary capillary because gases move from higher concentration to lower concentration.
By this process the oxygenated blood reaches to the heart from lungs and heart then pump this oxygenated blood to other body tissues.The partial pressure of oxygen in alveolus is 104 mmHg and in venus blood is 40 mmHg.
