The carbon dioxide carried in the blood is actually combined with water and carried in the red blood cells in the form of carbonic acid, which has a dissociation constant:
H₂CO₃ ↔ H⁺ + CO₃⁻
When the pH of the blood decereases, the concentration of H⁺ ions in the blood becomes high. This causes the equilibrium to shift backwards, as per Le Chatelier's principle. The H⁺ ions are converted back to carbonic acid and the pH is increased. The opposite occurs when the pH is too high.
Answer:
d) 2v
Explanation:
Since, root mean square speed of a molecule,

Where,
k = Boltzmann constant,
T = temperature of gas,
m = mass of molecule,
Also, the temperature of a gas,

Where,
p = pressure of the gas,
V = volume,
n = number of moles of gas,
R = universal gas constant,

If V = 2V and p = 2P
Then,


Hence, if rms speed of a gas molecule under initial conditions is v then rms speed of a molecule will be 2v
i.e. option d is correct.
Answer:
- 9 out of 16 have gray fur and black eyes
- 3 out of 16 have gray fur and red eyes
- 3 out of 16 have white fur and black eyes
- 1 out of 16 have white fur and red eyes
Explanation:
Based on the image attached to this question, the question involves two genes. One coding for fur color and the other for eyes color. The alleles for gray fur (G) and black eyes (B) are dominant over the alleles for white fur (g) and red eyes (b).
Please find attached to this answer an image containing a completion punnet square using the gametes illustrated. According to the punnet square in the image, the following proportions of offsprings were obtained:
- 9 out of 16 have gray fur and black eyes (G_B_)
- 3 out of 16 have gray fur and red eyes (G_bb)
- 3 out of 16 have white fur and black eyes (ggB_)
- 1 out of 16 have white fur and red eyes (ggbb)
i believe it's <u>B. An atom of iron</u>
