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 :)
The answer is a. the abiotic components of an ecosystem
Options found elsewhere:
-always genetically identical to one parent
-always genetically identical to both parents
-never genetically identical to one parent
-sometimes genetically different than both parents
Answer:
-sometimes genetically different than both parents
Explanation:
Protists are eukaryotes that cannot be classed as animals, plants, or fungi. They are quite diverse. Examples include amoeba, plasmodium, and slime mould.
Because they are so diverse, protists also have very different modes of reproduction. Some protists undergo asexual reproduction, where they simply make a copy of themselves without a mate. Others undergo sexual reproduction.
Therefore, the only option that can be correct is "-sometimes genetically different than both parents" .
If they were always genetically identical to one parent or both parents, that would mean that sexual reproduction could not be possible. If they were never genetically identical to one parent, that would mean that asexual reproduction could not be taking place.
UAAAUC hope this helps !!
