List 3 things you know, want to know and want to learn about the immune system.

This is all opinionated and I cannot answer it, as it is something you should want to know and learn.

However, here are some tips to make this easier.

1. When it comes to something you know, make sure to go into detail so it doesn't seem like you are slacking.

2. When you have something you want to know, you can look up, "fun facts about the immune system", and add interesting facts without the answer. So, you could put, "I would like to know what is the use of the immune system", and if possible, write down what it does.

3. Use similar things as I did on tip #2.

4. Don't forget to include proper spelling, grammar, and punctuation. If you fail to do this, then you might get some points taken off.

5. Be as factual as possible. Check your resources from at least 3 websites to make sure they are true. If they are true, you will gain the proper amount of points.

6. Ask for help if needed. Don't be afraid to ask for help when it's needed.

7. Add citations. If there is something you quote word for word, you need to add a citation, so that you stay inside the legal requirements.

8. Don't forget to always add your own opinion, not others. This is opinionated, not completely fact based. (except on what you know)

9. Have fun!

I hope this helped!

the corpus luteum secretes estrogens and progesterone. the latter hormone causes changes in the uterus that make it more suitable for implantation of the fertilized ovum and the nourishment of the embryo. if the egg is not fertilized, the corpus luteum becomes inactive after 10–14 days, and menstruation occurs.

i hope this : )
