If a hemoglobin molecule comes into close contact with a respiring cell, the presence of CO2 in the environment will cause hemog
lapo4ka [179]

Answer:

No, when the concentration of carbon dioxide is high, such as in peripheral tissues, CO2 binds to hemoglobin and the affinity for O2 decreases, causing it to release.

Explanation:

The O2 molecule is reversibly combined with the heme portion of the hemoglobin. When the partial pressure of O2 is high, as in the case of pulmonary capillaries, for example, the binding of O2 to hemoglobin and the release of carbon dioxide are favored, this is known as the Haldane effect. If, on the contrary, when the concentration of carbon dioxide is high, such as in peripheral tissues, CO2 is bound to hemoglobin and the affinity for O2 decreases, causing it to release, this is known as the effect Bohr.

All the following are true of the movement of Earth's atmosphere except :
zheka24 [161]

Answer:

All  are true of the movement of Earth's atmosphere except :

d. Warm air is less dense than cool air so it tends to sink towards the Earth's Surface.

Explanation:

  • When gases heat up, their volume increases and  density decrease.
  • A decrease in density causes a substance to become lighter.
  • Thus, when air warms up due to heat from the sun its density decreases and it gets lighter.
  • So, it will move up.
  • The Cooler air in turn is denser and heavier so it will sink towards the Earth's surface.
  • Hence, the statement d , which states that 'warm air is less dense than cool air so in tends to sink towards the Earth's Surface' is FALSE.
