I can help you. Please post your question. :)

OpenStudy (anonymous):

Figure 20-1 Which structure or structures shown in Figure 20-1 have key differences in bacteria and archaea? A and C A and B D only A only

OpenStudy (anonymous):

I have one more question

OpenStudy (anonymous):

after this one

OpenStudy (anonymous):

That's fine. I'm reviewing your first question. Are you completely lost, or do you have some idea?

OpenStudy (anonymous):

completely lost could ou explain them

OpenStudy (anonymous):

you

OpenStudy (anonymous):

Of course! It'll take me just a sec to type it all up. Can I ask for two minutes? :)

OpenStudy (anonymous):

certainly

OpenStudy (anonymous):

Here are some of the biggest differences between bacteria and archea: Bacteria and Archaea differ in: ☼ Cell wall construction and membrane lipid arrangement. ☼ All bacteria have peptidoglycans in the cell wall whereas the archaea do not. ☼ Archea and Bacteria also have different RNA polymerases, which means that they synthesize (create) proteins differently. I'm going to include some pictures to help you get a visual. One of them may look especially familiar to you...

OpenStudy (anonymous):

Sorry, having some trouble with the computer. It's going kind of slow for a minute...

OpenStudy (anonymous):

what did I post a picture of

OpenStudy (anonymous):

@tafkas77

OpenStudy (anonymous):

You posted a picture of bacteria. (Sorry, had to reboot my computer).

OpenStudy (anonymous):

ok which letters in my picture are part of the differences because I dont know what part each letter is for

OpenStudy (anonymous):

The biggest difference that you can automatically single out from this picture, is the cell wall, which, since it's bacteria, is made with peptidoglycan. Archea do not have this type of cell wall. This is represented by an "A" on your picture. "B" is reffering to the plasma membrane in the bacteria, but both archea and bacteria have a plasma membrane. "C" is poitning to those little dots - those are the ribosomes. Archea do not have the same ribosomes (or R(ribosomal) RNA polymerase) as bacteria do. "D" is pointing to those spiky things, called, pili. That can be found in both archea and bacteria, as well. "E" is pointing to the circular DNA in the cell, which both archea and bacteria have. Do you get this?

OpenStudy (anonymous):

yes so the answer is A and C do you have time for one more question

OpenStudy (anonymous):

Yes, I do. And you were correct! Great job! :)

OpenStudy (anonymous):

2. Which of the bacterial cells shown in Figure 20-2 is a coccus? A B C none of the above

OpenStudy (anonymous):

@tafkas77

OpenStudy (anonymous):

this is my last question

OpenStudy (anonymous):

for now at least

OpenStudy (anonymous):

I'm here. I'm reading it. Just want to make sure I'm seeing this right!:) Ha ha *for now*

OpenStudy (anonymous):

Okay. I'm back. (Stupid computer wouldn't let me type.) Cocci are unicellular and often have a circular or ovular shape. They commonly link together to form long chains. Do you see which one it is, now?

OpenStudy (anonymous):

*Long chains or clumps.

OpenStudy (anonymous):

so the answer is picture A

OpenStudy (anonymous):

They tried to trick you with this one. Cocci are usually circular, but if they are ovular, they are fat and short - not long and skinny.

OpenStudy (anonymous):

so it is picture c because they are circular and they are making a chain

OpenStudy (anonymous):

Yes! :D Good job. :)

OpenStudy (anonymous):

thanks here is a medal you earned it

OpenStudy (anonymous):

Wow, thank you! I'm giving you one, too, because you actually wanted to learn - not just get the answer. Plus, you stuck with me even though I was having some tech problems. Now THAT's dedication. :) Good luck with your studies! :)

OpenStudy (anonymous):

I noticed a post s on another kids questions saying you arnt good a at math if you need help ask me I am a grade ahead in math

OpenStudy (anonymous):

it said you always ask math hero but I am on more so if I am on but he is not ask me and I will do what I can

OpenStudy (anonymous):

Wow, thank you! I'm pretty good in Algebra and Geometry, but anything beyond that puzzles my brain. I help where I can, though. I appreciate this! You rock! :D

OpenStudy (anonymous):

just fan me my computer is freaking out today and wont let me fan anyone

OpenStudy (anonymous):

I'm trying to; but I can't! I don't think it's the computers, it might be OS. I can't see smartscores for anyone. :/

OpenStudy (anonymous):

me either

OpenStudy (anonymous):

hmmm... it must be OS, then. Aww, geez. Well, I will fan you as soon as I can! I appreciate math help! :D

OpenStudy (anonymous):

it wont even show me my smart score

OpenStudy (anonymous):

Me either! D:

OpenStudy (anonymous):

oh and I forget my password alot so I will always use the user name loser and then numbers so you can recognize me

OpenStudy (anonymous):

Oh, okay! Thanks! Well, I've got to go! Talk to you soon! ~Tafkas out! :D

OpenStudy (anonymous):

bye

OpenStudy (cagliero423):

The answer to the first question is actually A and B. I just took this haha
