Explanation / Answer
1). (b) An ectopic pregnancy occurs when the fertilized egg implants in the uterus ------> FALSE
An ectopic pregnancy occurs when the fertilized egg implants somewhere outside other than in the uterus.
2). (b) When 2 eggs are simultaneously ovulated and fertilized the result is Fraternal twins -----> TRUE
3). (b) when 2 egg are fertilized at by the same sperm, the result is identical twins ----------> FALSE
4). (a) 2 days before and 1 day after ovulation
For conception to occur, intercourse must take place within a certain 3 day window i.e. 2 days before and 1 day after ovulation becuase a sperm cell can survive for 48 hours and an egg cell can survive for 12 to 24 hrs.
