Answer:
D. Northern, Southern
Explanation:
The Northern and Southern Hemispheres experience opposite seasons and different day lengths, no matter what time of year.
B. Mutualism, because both parties are benefiting from the other.
B, a nucleus. Nuclei are membrane-bound organelles inside eukaryotic organisms. Eukaryotes are protists, fungi, plants, and animal cells. A bacteria is not a eukaryote, it is a prokaryote, so it does not have the membrane-bound structure of the nucleus.
Be careful, though, bacteria still have DNA. It is simply located in the center of the cell and is not encased in a membrane.
Hi There!
Tell me a little about prokaryotic and eukaryotes.
What do these types of cells have in common?
How are they different?
2 very common similarities between the types of cells is that they both have a certain type of structure and all cells have a plasma membrane, DNA, ribosome, etc. They are different in a way that eukaryotes have a "membrane-bound organelle" which usualy includes it having a nucleus. Whats cool is that eukaryotes can be multicellular or singled celled> For Example, plants, insects, and fungi. Prokaryotes don't have a nucleus or organelle (membrane bound).
Hope This Helps :)
