Two pink-flowering plants are crossed. the offspring percentages are 25% red, 25% white and 50% pink. what would the parent's genotypes be?
a. both homozygous dominant
b. both homozygous recessive
c. both heterozygous
d. one homozygous dominant, one homozygous recessive

When red crosses with white flowers to give pink flowers, we are looking at incomplete dominance, i.e. the offspring is a blend (pink) of the parents' characteristics (red or white).

Since we're given in the question two pink flowers crossed to give 25% red, 25% whit and 50% pink, we would be thinking of a punnett square between RW and RW, to give

RR RW

RW WW

Since both parents are RW, that makes both parents heterozygous.

hypoxemia refers to a below usual concentration of oxygen in the blood, mainly in the arteries. hypoxemia is an indication of an issue associated with circulation or breathing and may lead to various symptoms like shortness of breath.  

the condition is identified by determining the level of oxygen in the blood sample obtained from an artery. it can also be predicted by determining the oxygen saturation of the blood with the application of a pulse oximeter.  

the normal arterial oxygen is about 75 to 100 mm hg. the values underneath 60 mm hg is generally considered with the requirement for supplemental oxygen. the normal pulse oximeter readings generally range between 95 to 100 percent. the values under 90 percent are regarded as low.  

in the given case, the oxygen saturation is measured at 93 percent, hence, there is no need to administer oxygen, that is, one should withhold oxygen.
