Answer:
An example of oxygen–hemoglobin (O2–Hb) dissociation curves from (A) one penguin at pH 7.5, 7.4 and 7.3, and (B) the emperor penguin, the bar-headed goose (Anser indicus) (Black and Tenney, 1980) and the domestic duck (Anas platyrhynchos, forma domestica) (Hudson and Jones, 1986) at pH 7.4. Note that as for the bar-headed goose, the O2–Hb dissociation curve of the emperor penguin is significantly left-shifted as compared with the domestic duck (and most birds). The bar-headed goose photo is courtesy of Graham Scott; the domestic duck photo is by Maren Winter (licensed under the terms of the GNU Free Documentation License, Version 1.2 or any later version); the penguin photo is by J.M.
Explanation:
The resulting regression equations from the plots of log[SO2/(100–SO2)] vs log(PO2) (all saturation points, all penguins combined) were:
pH 7.5: log[SO2/(100–SO2)] = 2.92589 × log(PO2) – 4.24338 (N=43, r2=0.98, P<0.0001),
pH 7.4: log[SO2/(100–SO2)] = 2.94767 × log(PO2) – 4.39858 (N=70, r2=0.98, P<0.0001),
pH 7.3: log[SO2/(100–SO2)] = 3.04945 × log(PO2) – 4.72019 (N=38, r2=0.99, P<0.0001),
pH 7.2: log[SO2/(100–SO2)] = 3.15958 × log(PO2) – 4.97618 (N=9, r2=0.99, P<0.0001).
- The bond polarities of a molecule of ammonia (NH₃) are <u>polar</u>.
- The molecular shape of a molecule of ammonia (NH₃) is <u>trigonal pyramidal</u>.
- The molecule of a molecule of ammonia (NH₃) is <u>polar</u>.
In Chemistry, there are two (2) main types of covalent bond and these include the following:
- Polar covalent bond.
- Non-polar covalent bond.
Electronegativity can be defined as the ability or tendency of the atom of an chemical element to attract any shared pair of electrons.
In Chemistry, the difference in electronegativity between an atom of nitrogen (N) and hydrogen (H) causes electrons to preferentially orbit an atom of nitrogen (N), thereby, making the bond polar.
Furthermore, the molecular shape of a molecule of ammonia (NH₃) is <u>trigonal pyramidal</u> and the molecule of a molecule of ammonia (NH₃) is <u>polar</u>.
