The answer is heterotrophic
Answer: No, because the lysosome and the cell, membrane are needed.
If cells didn't have a membrane, the cell would just melt everywhere. If we didn't have lysosomes, there would be a lot of toxins in the cells.
Hope this helps :)
From the question you can immediately infer that it's either B or D, as A and C basically mean the same thing and it isn't anything related to a microscope. I can tell you now that you don't need an electron microscope to see cells, they're only required for the atomic level.
Therefore, the answer is B, as you can't see cells without a microscope but you only need a light microscope, not an electron microscope.
Mutation can be both beneficial and harmful.
A very common beneficial mutation is camouflage and natural selection. The organism will acquire the change and pass it on to their offspring.
A harmful mutation can be diseases or a common harmful mutation, Down syndrome. Which gives a person an extra chromosome.
Since you provide no options, here are the usual parts of scientific method :
- Idea / question which answer you want to find out
- Research , collecting all kinds of data
- Hypothesis , an explanation that is made at the starting point, before the experiment
- Experiment , to find out whether your hypothesis is right
- Analyze the data that you got from the experiment
- Conclusion, your final judgement based on the result of your experiment
