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 />
Answer:
This is due to the event of Speciation that happened for the rodents in Island B but not for the rodents in Island C.
Explanation:
- Due to splitting of the population,
- The sub-population of rodents formed in Island B are B1 and B2.
- The sub-population of rodents formed in Island C are C1 and C2.
- In case of Island B, each of the B1 and B2 sub-populations that got split from each other developed certain mutations that were necessary for them to adapt to the particular diverse environment each of them were exposed to, through the period of 50,000 years. These mutations were so varied that reproductive isolation was generated between them that resulted in each of them to develop into different species.Hence, speciation happens here and B1 and B2 are incapable of inter-breeding.
- In case of Island C, each of the C1 and C2 sub-populations that got split might have got exposed to similar environmental change or no environmental change or the environmental change might have been too small to cause drastic change in each of the sub-populations. As a result of this the two sub-populations might have acquired certain mutations to adapt to the environment each of them were exposed to, through a period of 100,000 years. These mutations might not have been too variable or contrasting to cause reproductive isolation between C1 and C2. Hence, no new speciation happens here and C1 and C2 are capable of inter-breeding.
The red blood cells able to move through narrow vessels to carry oxygen throughout a multicellular organism because they are small because they lack a nucleus. Option D
<h3>What are red blood cells?</h3>
The red blood cells are the ones that carry hemoglobin that is responsible for the transport of oxygen in the body. Now we know that the blood is responsible for the supply of oxygen across the body and this is why the red blood cells are important.
Thus, the red blood cells able to move through narrow vessels to carry oxygen throughout a multicellular organism because they are small because they lack a nucleus.
