@:P You're saying get off of this website and do your own work while you're on this website. Not to sound rude but you're acting hypocritically. I do agree with you it's good to do your own work and solve problems by yourself and NOT CHEAT, but you cannot prove that point if you're on this website yourself.

I need help
I love how everyone only starts telling this person to do their own work when one person says it. And don’t worry, I already know everyone who even views this site has thought about cheating, or already has before. You’re not hidden, but I won’t expose your hiding spot.. You’re not a saint for not cheating, and we get that it’s wrong. A lot of the kids who use sites like Jishka and brainly use them because half of the time our schools do NOT prepare us for some of these questions. In this subject, Science, I did not receive of psychical textbook from my school. You scrape whatever info they give you out of the online slides and make do with that. And don’t call someone out of their name and “get a good laugh” just because they need help and you don’t. You sound like a jerk.
you want all the awsners

I also 100% agree with @A mildly agitated person.
LAST SCIENCE TEST OF THE YEAR THANK THE GODS.
Sk8ter gal is 100% right
I also agree with Perfect score
24. Science is a continuous progression of study because science experiments have to be repeated in order to prove the already existing answers. There are always new things that are found just because a scientist was curious enough to continue someone elses work. Science doesnt always have the exact answers to things, so the answers that are already available are the best fit. As new things are found, the already existing answers are upgraded and improved for a better fit.
pls change ur answers a bit if ur using this one so no one gets caught stay safe peeps<3
