The sequence that correctly describes the route that an egg takes through the female reproductive system would be option d. Ovary - Fallopian tube - Uterus. The mature egg is released by the ovary into the Fallopian Tube. Once it is fertilized, it is embedded in the wall of the uterus and this is where the unborn baby develops. If fertilization does not happen, the endometrium is broken down, which results in menstruation.
A jet stream forms high in the upper troposphere between two air masses<span> of very different temperature. The greater the temperature difference between the air masses, the faster the wind blows in the jet stream.
</span>.
.
So "Differences in temperature between two air masses" is the answer
