Your answer for this problem is going to be :T-A-A-G-U-T-U-G
        
                    
             
        
        
        
Plant cells have a cell wall, but animals cells do not. Cell walls provide support and give shape to plants. Plant cells have chloroplasts, but animal cells do not.
Hope this helps :) 
 
        
                    
             
        
        
        
1) False. Scientists may predict something but realize a difference soon after before the test, so they could definitely change the hypothesis if they want. It’s only AFTER the experiment they cannot. Because a hypothesis is like a “guess” as to what’s going to happen, right? 
2) False. A hypothesis can’t be “valid” because it’s literally a prediction. 
3) True. Especially if you’re doing a chemistry lab, it’s really important things are done in order or else the product might result as something else you were expecting, or can be very dANGEROUS
4) True. The conclusion must be based on data because it’s the observation that was seen. 
Hope this helps!! I could have answered in short form but I just wanted to make them understandable:)
