Answer:
I think the answer is that prokaryotes have a nucleus and eukaryotes do not.
Explanation:
It is the first thing I think of when I think of a difference between the two.
Prokaryotic cells, like bacteria, are simpler, smaller, and do not have a nucleus or other membrane-bound organelles. Their genetic material is loosely housed in the cell. On the contrary, eukaryotic cells, like those of animals, plants, and fungi, have a nucleus, more complex structure, and contain various defined organelles.
The main difference between prokaryotes and eukaryotes lies in the cellular structure. Prokaryotic cells, like bacteria, are simpler and smaller than eukaryotic cells. They do not have a nucleus or other membrane-bound organelles. Instead, their genetic material is loosely housed in the nucleoid, a region within the cell.
On the other hand, eukaryotic cells, such as those of animals, plants, and fungi, have a more complex structure. They are larger and contain a nucleus where the cell's genetic material is stored. Eukaryotic cells also contain various other defined organelles, like mitochondria, endoplasmic reticulum, and Golgi bodies, that carry out different functions.

Answer: True
Explanation:
Unnatural occurences are those catastrophic events induced by humans which can exert drastic impact over the ecosystem. These may include deforestation, forest fire, intentional explosion, and others. This will result in loss of many species due to damage caused to the non-living physical environment.
Answer:
The electron microscope uses electrons to form images for this reason does not allow to observe living cells because they need to work in a high vacuum atmosphere, the samples require preparation through a long fixation process, which means that it is not possible to observe living cells. To observe a cell with this microscope, dead cells must be observed, after being fixed and stained with heavy metal ions.
In these microscopes it is not possible to observe the cells carrying out their normal behaviors (for example, migrating or dividing) under the microscope
B. a substrate.
C. an enzyme.
D. Both A and C
Plants store energy in form of starch usually in the roots and/or stem. When there is need for energy such in respiration, starch is converted to glucose which is then used to fuel the process of cellular respiration.
In animals, energy is stored in form of glycogen in the liver and muscle tissues. When there is demand for energy, glycogen is converted back to glucose, which is taken in by the cells and used to fuel cellular respiration
In both plant and animal cells, the purpose of respiration is production of ATP (or adenosine triphosphate), which is the form of energy that cells use.
