There are 5 steps of the scientific method:
1. Make an observation.
2. Form a question.
3. Form a hypothesis.
4. Conduct and experiment.
5. Analyze data and draw a conclusion.
Based off this problem:
1. It doesn't specifically say that an observation was made but since it says she's studying it, it may count as an observation???
2. No question is asked because it doesn't say that she is wanting to know what the effects are of sleep deprivation for twelfth graders during midterms.
3. There is no hypothesis stated because she is not making a prediction on the outcome.
4. I suppose the data collected that she turned in was the experiment so I'm pretty sure she did conduct the experiment.
5. She just turned in her data but no analysis or conclusion is said to be made.
Without further ado, it seems that three steps were actually left out but if I had to choose, I believe that steps 3 and 5 were left out but I may be wrong. Sorry I couldn't provide a direct answer but I hope my thought process is helpful.<span />
It should be karst limestone and it forms by erosion of rocks such as limestone that dissolved in water in a process called chemical weathering :)
Answer:
Adaptations develop when certain variations or differences in a population help some members survive better than others. The variation already exist with the population, but the variation comes from a mutation, or a random change in an organism's genes.
Multicellular organisms grow by producing more cells. As children, we get taller every year. That growth happens only because our bodies keep adding new cells. A sapling becomes a tree for the same reason.
But even after an organism grows up, its cells continue to divide. That's because cells wear out or get damaged.
