What refers to the two-step process in which bone tissue is recycled?

A. Fortified grains and cereals are excellent sources of folic acid, the synthetic form of folate (vitamin B9). Adequate folic acid intake before conception and during early pregnancy is crucial for proper neural tube development, which forms the baby’s brain and spinal cord. Consuming folic acid-rich foods or supplements has been shown to significantly reduce the risk of neural tube defects such as spina bifida and anencephaly.

B. While fresh citrus fruits contain some natural folate, the amounts are generally lower than in fortified grains and cereals. Relying solely on citrus fruits may not provide sufficient folic acid to meet the recommended daily intake for pregnant women.

C. Simple carbohydrates, such as sugar and refined starches, provide energy but do not contain significant amounts of folic acid or other essential micronutrients needed to prevent neural tube defects.

D. Linoleic and alpha-linolenic acids are essential fatty acids important for overall health, including brain and eye development, but they do not provide folic acid and are not effective in preventing neural tube defects.

A. Being underweight can disrupt hormonal balance, including reproductive hormones such as estrogen and testosterone. In women, this can lead to irregular menstrual cycles or amenorrhea, while in men it can affect fertility and overall endocrine function.

B. Excess adipose tissue is a health risk associated with being overweight or obese, not underweight. Underweight individuals typically have low body fat stores.

C. Iron deficiency anemia is more common in underweight individuals due to inadequate dietary intake of iron-rich foods. Low body weight may also reflect overall malnutrition, increasing the risk of deficiencies in iron and other essential nutrients.

D. High blood pressure is typically associated with overweight and obesity rather than being underweight. Underweight individuals are less likely to develop hypertension solely due to low body weight.

E. Delayed wound healing can occur in underweight individuals because inadequate caloric intake and nutrient deficiencies (such as protein, zinc, and vitamin C) impair tissue repair and immune function, making recovery from injuries slower.
