Answer:
15
Explanation:
According to linkage theory, two genes present on the same chromosome tend to get inherited together. So the gametes produced are not equal in number and parental type offspring are observed more in number than the new recombinant types.
Here, normal wings, red eyes (420) and vestigial wings, purple eyes (430) are most in number hence they are the parental type offspring.
Vestigial wings, red eyes = 80 : recombinant
Normal wings, purple eyes = 70 : recombinant
Distance between two genes in cM = recombination frequency = (total number of recombinants / total progeny)*100
= [(80+70)/(420+80+70+430)]*100
= (150/1000)*100
= 0.15*100 = 15cM
I believe it is Carbon Dioxide. When we take in Oxygen, we breathe out Carbon Dioxide.
<span>The nurse should check the boy's height and weight. If the boy were to lose a massive amount of weight it would mean that he would be unhealthy which may be a result of the prescription. If his weight was normal then it would indicate that the prescription has not negatively effected his body. The boy's height would work the same way, if it decreased for some reason, it was most likely caused by a adverse reaction to the medicine. If his height is unchanged that would be a positive sign.</span>
