Reptile [31]
PP-  purple homozygote
pp- white homozygote
Pp- purple hetrozygote

If these flowers cross, we obtain heterozygote offsprings with a genotype: Pp (100% of them will be like this)

Now, if those offsprings cross with each other: Pp x Pp
results:
  1/4 would be purple  homozygote -> PP
  1/4 would be white -> pp
  2/4 would be purple heterozygotes -> Pp
Genotipic ratio: 3:1 (3 are purple; 1 is white)

Which mineral would be found in greatest concentration in the plasma of the marathon runners?
andre [41]
The right answer is E. Sodium  (with 140mmol/L)

Sodium is the most important element in the blood and extracellular liquids of the body.The needs of an adult subject are of the order of 1 to 2 g of sodium per day. The normal diet is much richer than our actual needs, about 4g, so it can largely compensate for the needs of an athlete or a runner.
Losses are majoritarly by feces and sweat. The kidney is able to reabsorb almost all the sodium that is filtered: urinary losses can be tiny.
