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.

Q8. A researcher wants to study the effectiveness of a pill intended to reduce stomach heartburn in pregnant women. The researcher chooses randomly 400 women to participate in this experiment for 9 months of their pregnancy period. They all need to have the same diet. The researcher designs two groups of 200 participants: One group take the real medication intended to reduce heartburn, while the other group take placebo medication. In this study what are: Independent variable: Dependent variable: Control variable: Experimental group: " Control group: If the participants do not know who is consuming the real pills and who is consuming the sugar pills. This study is It happens that 40% of the participants do not find the treatment helpful and drop out after 6 months. The researcher throws out the data from subjects that drop out. What type of bias is there in this study? If the company who makes the medication funds this research, what type of bias might exist in this research work?
