QUESTIONS WITH ANSWERS GRADED A+
◉ Identify role of DNA changes in congenital abnormalities. Answer:
Mutations in genes or chromosomal abnormalities
◉ How does development disrupts congenital abnormalities? Answer:
Alterations of DNA
◉ Describes factors that disrupt homeostasis and how disruptions affect
wellbeing. Answer: (ex) Fluid and electrolyte shifts can cause n/v or

◉ Explain RAAS. Answer: Renin-angiotensin-aldosterone system
1. Reduce blood flow causes kidneys to release renin
> produce angiotensin I > converts angiotensin I to angiotensin II >
vasoconstriction > release aldosterone > kidneys conserve sodium and
water > Result less water lost in urine and blood pressure maintained.

joint pain and butterfly rash
◉ Describe Myasthenia Gravis. Answer: It is an autoimmune disorder
where antibodies attack own Ach receptors. This causes weakness of
skeletal muscles over the course of the day, along with ptosis, double
vision, and difficulty swallowing.
