Answer:

See the answer below

Explanation:

a) Since the pink phenotype is heterozygous, the genotype would be RW.

b) The pink genotype is RW. Hence, a cross between two pink snapdragons will go thus:

          RW    x    RW

      RR    RW    RW    WW

<u>Expected genotypes:</u> 1/4 RR, 1/2 RW, 1/4 WW

<u>Expected phenotypes:</u> 1/4 red-flowered plants, 1/2 pink-flowered plant, 1/4 white-flowered plant.

In which of these systems can parts of the oxygen cycle be found?
Natalija [7]

The oxygen cycle can be found in all but the geosphere. There's oxygen in the atmosphere, so it has to be there, and the biosphere includes living things, which breathe oxygen, and water (hydrosphere) is made up of partly hydrogen, so there has to be oxygen there as well.

What specific key factor starts the breathing process in a newborn infant?
kvv77 [185]
Chemical factors: This is due to internal stimuli. Changes in the blood such as decrease in O2, increase in CO2 and decrease in PH cause impulse in the carotid artery which stimulates the respiratory centers in the medulla and cause breathing.

Mechanical factors: also called external stimuli. Compression of the fetal chest during delivery forces small amount of lung fluid out of the lungs. This increase in pressure in the chest draws air into the lungs.
