2. Which types of diabetes are characterized by the body's cells becoming resistant to insulin? (Select all that apply)

A. Gestational diabetes
B. Type II diabetes
C. Type I diabetes
D. Both A and B

Correct answer: D

Rationale: In both gestational diabetes and Type II diabetes, the body's cells become resistant to insulin, leading to elevated blood glucose levels. Insulin resistance in these types of diabetes prevents glucose from entering the cells, causing it to accumulate in the bloodstream. On the other hand, Type I diabetes is characterized by the body's inability to produce insulin because the immune system mistakenly attacks and destroys the insulin-producing cells in the pancreas. Therefore, the correct answer is both A and B. Choice C, Type I diabetes, is not characterized by insulin resistance but rather by the body's inability to produce insulin. Therefore, it is incorrect. Choice D, Both A and B, includes the correct options of gestational diabetes and Type II diabetes, making it the correct answer.

3. Dina, 17 years old, asks you how a tubal ligation prevents pregnancy. Which would be the best answer?

A. Prostaglandins released from the cut fallopian tubes can kill sperm
B. Sperm cannot enter the uterus because the cervical entrance is blocked
C. Sperm can no longer reach the ova, because the fallopian tubes are blocked
D. The ovary no longer releases ova as there is nowhere for them to go

Correct answer: C

Rationale: The correct answer is C: 'Sperm can no longer reach the ova because the fallopian tubes are blocked.' Tubal ligation works by blocking the fallopian tubes, preventing sperm from reaching the egg for fertilization. Choice A is incorrect because prostaglandins are not released from the cut fallopian tubes to kill sperm. Choice B is incorrect as the cervical entrance being blocked does not relate to tubal ligation. Choice D is incorrect because tubal ligation does not affect the release of ova from the ovary.
