Hi @helen001

Did you create these images yourself?

I invite members who use the steemstem tag to be extra careful about the content they post. It should be original and made by themselves, respecting copyrights.

@Steemstem is a community aiming to support posts about Science, Technology, Engineering and Mathematics.

We welcome new members interested about STEM on our discord channel

Please read here what it means to be a member of the steemstem community and the standards of a post.

Please note that there are specific guidelines to follow when crafting stem content. The originality, creativity, correct sourcing is of great importance and are important factors that qualify (or not) stem articles.
