Answer:
The hemoglobin molecule has four binding sites for oxygen molecules: the iron atoms in the four heme groups. Thus, each Hb tetramer can bind four oxygen molecules.
Answer:
Oxygen binds reversibly to harem, so each hemoglobin molecule can carry up to four oxygen molecules. Hemoglobin is an allosteric protein; the binding of oxygen to one harem group increases the oxygen affinity within the remaining harem groups.

The amount of dissolved oxygen decreases with increase in temperature.
However, in chart 1 it was observed that the amount of dissolved oxygen increases with increase in temperature.
What is the relationship between dissolved oxygen and temperature?Dissolved oxygen is the amount of oxygen dissolved in water at a given temperature. Dissolved oxygen is important to aquatic animals for respiration.
The relationship between dissolved oxygen and temperature is that dissolved oxygen increases with decrease in temperature and vice versa.
Based on chart dissolved oxygen initially had a linear relationship with temperature. This, however is contrary to the expected results.

Most carbon is stored in rocks and sediments, while the rest is stored in the ocean, the atmosphere, and in living organisms.
Which statement regarding viral diseases is false? AIDS was around for decades before becoming a widespread epidemic. Very few new human diseases have originated in other animals because the genetic differences are too great. RNA viruses tend to have an unusually high rate of mutation because their RNA genomes cannot be corrected by proofreading. New viral diseases often emerge when a virus infects a new host species.
The statement 'very few new human diseases have originated in other animals because the genetic differences are too great' regarding viral diseases is false.
What is a viral disease?A viral disease is an infection caused by a virus that may be spread to cause pandemic and epidemic situations.

Why doesn't a gummy bear grow as much in sugar water as it does in normal water?
Answer:
In comparison to the gelatin molecules in the candy, salt or sugar ions in water are significantly smaller. Water molecules go to a location with more solute to balance things out due to osmosis. The problem is that the water is trapped inside the candy and cannot escape. Because the Gummy Bear can't get any smaller, it keeps the same size.
