Cell division & reproduction

The G1, S and G2 phase together make up the:

1. Cell cycle
2. Interphase
3. Mitosis
4. Growth phase

The fallopian tube/oviduct

1. 10
2. 5
3. 1
4. 13

What phase of mitosis do these images show?

Prophase

Metaphase

Anaphase

Telophase

Which of these hormones does not increase during pregnancy?

1. Progesterone
2. Oestrogen
3. HCG
4. FSH

Match the hormone with the correct graph

This is a really hard question so use your notes and your textbook (pages 93+94) to know when the peak is of the hormones

FSH

LH

Oestrogen

Progesterone

Which of the following statements best describes the placenta?

1. it is a structure that remains in the ovary after the egg has been discharged, it produces human chorionic gonadotropin
2. it is an organ formed in the uterus during pregnancy, it produces hormones that help a pregnancy go smoothly and connects the mother and fetus
3. it is the organ that holds eggs waiting to be fertilised, in the later stages of pregnancy it becomes inactive
4. as the placenta is being formed, it produces the first detectable hormone of a pregnancy; this hormone is detected by blood or urine pregnancy tests

C is a process happening during.. in ..

1. Anaphase / Meiosis 1
2. Anaphase / Mitosis
3. Metaphase / Meiosis 1
