In the United States, pregnant women are warned not to drink water from lakes that lie near abandoned mines. Introduction: The exogenous agents like drugs, chemicals, viruses, and infectious elements that cause birth defects are called teratogens. The development of humans ais divided into two main periods: embryonic period (end of week 8) and fetal period (remaining time in utero). Teratogens generally effect these crucial time periods between week 3 to 8.

Expert Solution & Answer

Explanation of Solution

Abandoned mines often release water-soluble crude oil components that act as teratogenic molecules. A study revealed that in zebrafish embryo exposed to oil spill components produce larvae with developmental anomalies including reduction in size of head, gill, and thoracic cartilages associated with cranial neural crest migration. Often lakes near abandoned mines can be place of vector-borne diseases producing novel form of virus or bacteria. The mosquito-borne Zika virus can cause a birth defect microcephaly characterized by small brains and heads. These virus directly infect neural progenitor cells of the fetal cortex, resulting in death of cells causing smaller brain and head of newborn.

Conclusion

The pregnant women are warned not to drink water from lakes that lie near abandoned mines because they can contain teratogens causing birth defects in developing fetus.

Older adults have unique challenges in terms of their nutrient needs and physiological changes. Some changes may make it difficult to consume a healthful diet, so it is important to identify strategies to help overcome these obstacles. From the list below, choose all the correct statements about changes in older adults. Select all that apply. Poor vision can make it difficult for older adults to get to a supermarket, and to prepare meals. With age, taste and visual perception decline. As people age, salivary production increases. In older adults with dysphagia, foods like creamy soups, applesauce, and yogurt are usually well tolerated. Lean body mass increases in older adults.

When physical activity increases, energy requirements increase also. Depending on the type, intensity, and duration of physical activity, the body’s requirements for certain macronutrients may change as well. From the list below, choose all the correct statements about the effects of increased physical activity or athletic training. Select all that apply. An athlete who weighs 70 kg (154 lb) should consume 420 to 700 g of carbohydrate per day. How much additional energy an athlete needs depends on the specific activity the athlete engages in and the frequency of the activity. Those participating in vigorous exercise should restrict their fat intake to less than 15%% of total energy intake. Athletes who are following energy-restricted diets are at risk for consuming insufficient protein. The recommendation to limit saturated fat intake to less than 10%% of total energy intake does not apply to athletes or those who regularly engage in vigorous physical activity.
