Hi nees,
I would like to point out some areas you need to take note of; to help you create better STEM contents.
First of all, you need to make your post a little more detailed. And try to include references in your post. This would substantiate your assertions, and make your posts steemstem curation-worthy.
Also try to include sources of your images, and use only copyright-free images. You can refer to this guideline on image sourcing.
You can also include an introduction and a conclusion.
Thanks and cheers
