I have a 300-word document, and I need to do the following in Word. Not sure which function to use-been googling and watching videos for hours!

- Bold the first word of every sentence
- Underline every 10th word in the writing sample, excluding the header
- Highlight every word in the writing sample that starts with a vowel in yellow
- Highlight every word in the writing sample that ends with a vowel in blue
- Highlight every word in the writing sample that both starts and ends with a vowel in green
