Pregnancy, adolescent growth and adulthood past 70, compared nutrient by nutrient, with every shifted reference value explained by physiology: an SC115 Unit 9 life stage comparison. Searches like "sc 115 unit 9 assignment example", "sc115 unit 9 sample" and "sc115 unit 9 example" land here.
What a finished SC115 Unit 9 life stage comparison looks like
A three-column table is the centerpiece, one column per stage, with rows for the nutrients chosen. Pregnancy carries folate at 600 mcg dietary folate equivalents, explained through DNA synthesis in rapidly dividing cells and neural tube closure in the first weeks, often before pregnancy is recognized, and iron at 27 mg for an expanding blood volume and fetal stores. Adolescence carries calcium at 1,300 mg, tied to the years when most peak bone mass accrues. Adults past 70 carry vitamin D at 20 mcg, reflecting reduced skin synthesis, and vitamin B12, where lower stomach acid limits its release from food proteins. Prose beneath the table takes each row and states the mechanism in two or three sentences, sourced to the reference intake reports.
How a SC115 Unit 9 example is structured
The basis of the comparison comes first: which reference intake tables are used, their issuing body and year, and which age and sex bands represent each stage. The table follows. Analysis is then organized by stage, and within each stage by nutrient, in a consistent pattern: the reference value, the comparison value for a nonpregnant adult of similar age, the physiological reason for the difference, and a food or fortification source. A cross-stage paragraph looks for patterns, typically that energy needs change less than several micronutrient needs, and that absorption efficiency shifts as well as requirement. A conclusion summarizes without offering guidance to any individual. Several samples add a brief note on where reference values rest on limited evidence, particularly in the oldest age bands, before the references.
Comparison baseline stated
Each stage's value is set against a nonpregnant adult of similar age, so the size of every change is visible at a glance.
Timing explained for folate
The brief explains why folate matters before pregnancy is typically known, a point about developmental timing rather than quantity.
Growth tied to bone accrual
Adolescent calcium is linked to the window when bone mineral is laid down fastest, not simply to being young.
Absorption changes in later life
B12 and vitamin D are treated as problems of release, synthesis and activation as much as problems of intake.
Evidence strength noted
Where a reference value rests on thin data, the comparison says so rather than presenting every number as equally certain.
Where marks go in SC115 Unit 9
Deductions concentrate on changed values presented without reasons, a table of numbers with no physiology beneath it, which misses what such a comparison is for. Band errors are common: adolescent figures applied to all children, or a pregnancy value quoted for lactation. Units cause trouble with folate, where dietary folate equivalents and micrograms of folic acid are not interchangeable, and with vitamin D, where micrograms and international units get mixed. Some papers list every nutrient for every stage and explain none of them well; depth on a few scores better in most sections. Advice aimed at pregnant readers, or supplement recommendations for older adults, falls outside the assignment and draws comment. Sources need dates, since several reference values were revised in recent decades.

SC115 Unit 9 questions, answered
Can I choose different life stages?
Often, yes. Infancy, lactation and early childhood work well, as does comparing two adult age bands. Choose stages where reference values change for clear physiological reasons, since the assignment is graded on the explanation. If the prompt fixes the stages, stay with them, even where another pairing looks more interesting. Two sharply contrasting stages usually make a cleaner argument than four thin ones.
Why is folate listed in dietary folate equivalents?
Because folic acid from supplements and fortified foods is absorbed more efficiently than the folate naturally present in food. Dietary folate equivalents adjust for that difference so that intakes from both can be added. Using the right unit, and saying which one the table uses, avoids a frequent accuracy deduction in this unit.
Do I need to cover lactation separately from pregnancy?
Only when the prompt includes it. The two stages have different reference values for several nutrients, so if both appear, treat them separately. Mixing them in one row tends to produce figures that are correct for neither, and graders who know the tables will spot the blend quickly. Vitamin A needs, for example, rise further during lactation while iron needs fall.
