This question related to the Doppler effect, which states that the incident frequency of waves from a moving source is different from the actual frequency. The point where the actual frequency is observed is when the source is right next to the observer.

In horses, Chesnut hair color is recessive to black. The pacing gait is recessive to trotting and long hair is recessive to shor
Vitek1552 [10]

9:3: 3:1  is the phenotypic ratio showing traits as black and long hair : black and short hair: chestnut and long hair: chestnut and short hair when a chestnut horse heterozygous for pacing and hair length with a hybrid horse.

Explanation:

Dominant trait = black hair colour (BB,Bb), trotting (TT,Tt) , long hair (LL,Ll)

recessive trait = chesnut hair colour (bb), pacing gait (tt), short hair(ll)

cross between chestnut horse heterozygous for pacing and hair length will have alleles as BbLl

alleles for hybrid horse will also be heterozygous Bb, Ll

Punnett square to show the cross:

      BL         Bl       bL         bl

BL  BBLL  BBLl     BbLL    BbLl

Bl   BBLl    BBll     BbLl      Bbll

bL  BbLL  BbLl      bbLL     bbLl

bl    BbLl  Bbll       bblL        bbll

phenotype ratio

black and long hair : black and short hair: chestnut and long hair: chestnut and short hair

9:3: 3:1  is the phenotype ratio.

Under normal conditions, what would be the PRIMARY mechanism that his body would use to reduce the amount of PCO2 in the blood
sergeinik [125]

The pH of blood if pco2 drops to 35.0 mmHg is 7.459

The pH of the blood can be calculated using the Henderson- Hasselbalch equation, which explains the relationship between acid dissociation constant pKa and pH in biological and chemical systems.

pH = pK + log ( HCO3- / ( 0.03 * PCO2 ) )

pK is 6.1 for the bicarbonate buffer system.

HCO3- = 24mm

PCO2  = 35.0 mmhg

pH = 6.1 + log ( 24 / 0.03 * 35.0 )

    = 6.1 + log ( 24 / 1.05 )

    = 6.1 + log 22.8571

    = 6.1 + 1.3590

    = 7.459

Hence, the pH of blood is 7.459
