Answer:
Yes
Explanation:
You can identify an unknown substance by measuring its density and comparing your result to a list of known densities.
Density = mass/volume
When you divide the mass by the volume and compare the density to a list of known densities.
To calculate this we will use the light equation:

λ

We have Frequency

.
We know that speed of light in vacuum is

.
Since a unit of speed of light is m/s, we can change the unit of frequency Hz to 1/s, since Hz means cycles per second (f=1/T).
So:

Prokaryotic cells do not contain a nucleus or any other membrane-bound organelle, while Eukaryotic cells contain membrane-bound organelles, including a nucleus.
Based on the picture, how did the sunflowers show their competition? Why should they compete?
I choose this as a scientific question because there are numerous sunflowers that occupy the land. Living things try to survive with their environmental conditions. Thus, competition happens among the organisms.
