My answer: Because the actual thing you might be modelling might be too small or large to replicate, (for example you cannot draw a plant cell TO SCALE because it’s way too small to see with a bare eye).
And if the item is too big, you won’t be able to fit it in a small space; if you were to draw it or create it in 3D.
I hope this helps!
Sorry if the response is too short, try rewording if you need to :)
D. A plant using sunlight to make good
Answer:
D
Explanation:
Methanogens are prokaryotes and therefore have prokaryotic cells. They are single-celled archaea. They are found in hypoxic conditions like the first stomach of ruminants where they digest molecules like cellulose and produce methane as a byproduct. The rest are composed of eukaryotic cells which are much larger than prokaryotic cells and their organelles are membrane-bound (unlike prokaryotes).
Ok, I'm not 100% sure this is correct, given the context of the situation, but basically, the cell membrane helps the cell maintain homeostasis by keeping what needs to be in in & what needs to be out out. If it weren't for the cell membrane having the structure it does, all kinds of things could get into the cell & completely kill it from filling it with too much stuff, or the wrong things could get in (say, things with a really odd pH) & damage it badly. Or, it could let things get out extremely easily, such as enzymes and ions the cell needs to function properly.
Hope this helps!
Answer:
Other scientists would need to confirm the results by performing the same experiment.
Explanation:
According to this question, an experiment was conducted by an associate professor, using 20kids, to discover why children are better at problem-solving after exercise. He arrived at a result that Children who exercised showed a 5% increase in the P3 waves, which occur during decision- making.
However, in order for this findings by Charles Hillman to be generally accepted and recognized in the scientific community, which is a connection of several scientists, the results need to be confirmed by performing the same tests or experiment.
Note that, an experiment becomes a scientific theory if it has undergone series of repeatable tests. One of the key features of scientific experiment is that it must be repeatable.
