Hey there!
If there is a temperature difference between two objects, the object that has a higher temperature will want to level out its heat. Therefore, it will transfer the heat it needs to the other object if it allows until they are the same temperature.
I hope this helps!
The answer would be Haemoglobin.
The Haemoglobin is a red pigment found in RBCs of vertebrates that helps to transport oxygen to various tissues.
Vertebrate blood is bright red when it is oxygenated and dark red when it is deoxygenated. Some animals such as crustaceans or mollusks, use haemoglobin to carry oxygen instead of hemoglobin.
Hope This Helped!
C. Warm air is less dense than cooler air. Air density varies with the relative humidity (amount of water vapor molecules in the air) along with temperature.)
Zooplankton size variation:
1) picoplankton<span> - measure less than 2 micrometers
2) </span>nanoplankton -<span> measure between 2-20 micrometers,
3) </span>microplankton -<span> measure between 20-200 micrometers,
</span>4) mesoplankton - <span>measure between 0.2-20 millimeters,
</span>5) macroplankton<span> - measure between 20-200 millimeters,
6) </span>megaplankton - <span>measure over 200 millimeters (almost 8 inches). </span>
