A study has been conducted
69vym7dn dsc1d e0 v3x on the effect of hormonal contraception pollution on the mating calls of the adult male African clawed frog (Xenopus laevis). The spectrogram shows the frequency and volume of clicks (mating call) of control X.laevis and thos
ed1n dd6 vyc0v7sx 9m3e exposed to oestrogen.
1.Distinguish between the clicks in the spectrogram between the control X. laevis and the X. laevis treated with oestrogen in 1 second.
The graph shows the average duration of the X. laevis mating calls when exposed to the hormone oestrogen.
2.Describe the effect of oestrogen on the duration of the mating call.
3.Explain why it is important to have the X.laevis control group.
4.Identify the independent variable in this study.
5.1.Predict the reproductive success of X.laevis exposed to 29.6 ng/L of oestrogen.
5.2.Outline the possible consequences of oestrogen exposure on X. laevis.
