A group of ants attack a cicada, feed on it, and kill it, even though it is much larger than the ants. Which kind of relationship do the ant and the cicada share?
There are three kinds of symbioses. Three kinds of relations, between organisms. I'll tell you about all three. And you can choose the one you think is correct. 1. Mututalism --- Both organisms benefit from one another. 2. Commensalism --- One organism benefits, and the other is totally unaffected. 3. Parasitism --- One organism benefits, by hurting the other organism.
mututalism!
Do you know what a mutualism is?
Both organisms benefit from one another.
Right. Take a look at the question that you posted. The ants...KILLED...the cicada. The ants benefited from this. But what happened to the cicada? It frikkin died.
The cicada did not get any benefits.
ohh I get lol a little bit
an example of a prokaryote?
We're not done with the first question!
There are two organisms here: 1. The ants. 2. The cicada. The ants ATE AND KILLED the cicada.
Do you understand this?
kind of. im blonde.
I don't care if you have frikkin PURPLE hair.
Ants and cicadas are both animals. The ants ate and killed the cicada. In other words....on animal ate, and killed another animal.
So, the ants are happy. They got benefits, because they ate the cicada. What happened to the cicada? It died.
A "mutualism" is where BOTH organisms benefit, and are happy. Do you see why this ISN'T a mutualism?
ohh I get it so, Parasitism is the correct answer.
Right.
Good job. GOOD JOB.
yay!
Okay. So, now we're talking about "prokaryotes." "Prokaryotes" are organisms that don't have a NUCLEUS, inside of their cells. Bacteria do not have a nucleus. That's why they're called prokaryotes.
Which of the following cells would not have a well-defined nucleus but would have a thick cell wall and ribosomes? A. Onion Cell B. cloi bacteria C. Human Brain Cell
You really don't know this one?
A?
I'll give you a hint. TWO hints. No, THREE hints, actually. 1. Plant cells have a nucleus. 2. Animal cells have a nucleus. 3. Humans are made of animal cells.
so A
Onions are made of plant cells. Do plant cells have a nucleus?
yes so B
Right. Like we said before, in the very last question...bacteria are prokaryotes. They do not have a nucleus.
The presence of which organelle indicates that eukaryotic cells have evolved from prokaryotic cells?
If you have anymore questions, you can make a separate post. I would help but I'm a bit busy.
ok thanks though!
I have purple AND blond hair!!
