In corn the dominant allele P causes purple corn kernels, and the recessive allele p causes white kernels. On a separate chromosome pair is another gene effecting kernel texture. The dominant allele R causes round kernels, and the recessive allele r causes wrinkled kernels. If PpRr plant is crossed to another PpRr plant, what is the expected phenotypic ratio of the F1 plants? �

Select one:
a. 9 white wrinkled : 3 purple wrinkled : 3 white round : 1 purple round
b. 9 purple round : 3 purple wrinkled : 3 white round : 1 white wrinkled
c. All purple round
d. 3 purple round : 1 white wrinkled
e. 3 purple round : 3 purple wrinkled : 1 white round : 1 white wrinkled

the farther away the object is from the central star (the sun) it's gravitainal pull on the object is weaker when it is farther

explanation:

desert perennials often survive by remaining dormant during dry periods of the year, then springing to life when water becomes available. most annual desert plants germinate only after heavy seasonal rain, then complete their reproductive cycle very quickly.

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.  

the answer is definitely a
