I agree with @temitayo-pelumi. To be considered for steemstem upvotes please refer to the guidelines. In its current state, your post does not meet the guidelines. Here are a few suggestions to improve your post: include sources (pictures and info), work on your style (use markdown editor, or just look for style guides on steemit), work on your text quality (style, language). If you have trouble finding scientific sources I have a post that deals with finding scientific sources for free - Link.
Good luck and cheers!
