let me confirm morgan's answers for connexus.
it will just be a few moments.....
yes, i have confirmed this, and "Morgan"'s answers are 14/14 for connexus.
dis right biss MORGAN IS RIIIIIIIIGGGHHHHTTT!!!!! ,,,> w <,,,
Watch as all of you people above were actually Morgan trying to confirm her answers herself so that she/he can trick the WORLD.
Tripppyyyyy.
Also she right tho =)
Morgan all correct 14/14
ALSO most of my Unit Tests were dropped, I go to OCA, but I still had to do the practices.
Anyone else have this happen, if so, do you have an explanation lol.
omg thanks Morgan
#LifeSaver
#SpotifyHereICome!
Morgan is still right in may of 2021 😁
Like, and you will get good luck for the rest of your life.
aw, man I got a 50%😥
jk
lol🤣🤣🤣🤣🤣
I got a 100% thx @morgan

Radium is a chemical element with the symbol Ra and atomic number 88. It is the sixth element in group 2 of the periodic table, also known as the alkaline earth metals. Pure radium is silvery-white, but it readily reacts with nitrogen (rather than oxygen) on exposure to air, forming a black surface layer of radium nitride (Ra3N2). All isotopes of radium are highly radioactive, with the most stable isotope being radium-226, which has a half-life of 1600 years and decays into radon gas (specifically the isotope radon-222). When radium decays, ionizing radiation is a by-product, which can excite fluorescent chemicals and cause radioluminescence.
Radium, in the form of radium chloride, was discovered by Marie and Pierre Curie in 1898 from ore mined at Jáchymov. They extracted the radium compound from uraninite and published the discovery at the French Academy of Sciences five days later. Radium was isolated in its metallic state by Marie Curie and André-Louis Debierne through the electrolysis of radium chloride in 1911.[1]
In nature, radium is found in uranium and (to a lesser extent) thorium ores in trace amounts as small as a seventh of a gram per ton of uraninite. Radium is not necessary for living organisms, and adverse health effects are likely when it is incorporated into biochemical processes because of its radioactivity and chemical reactivity. Currently, other than its use in nuclear medicine, radium has no commercial applications; formerly, it was used as a radioactive source for radioluminescent devices and also in radioactive quackery for its supposed curative powers. Today, these former applications are no longer in vogue because radium's toxicity has become known, and less dangerous isotopes are used instead in radioluminescent devices.
do you have the answers Diana?
What the heck is going on. Oh and Morgan is right. those who say she isn't, maybe ur not in connexus? or in 7th grade.
oh my god thank you morgan!
Thx Morgan
FOR THE GOD QUEEN TYREEN!
1. The images above show particles in a medium. Which of the following shows the worst conditions for a sound wave to travel?
Thank you Morgan!
What are the answers for the quick check
Morgan is right!
am i the only one who has 24 questions lol
Morgan is correct for 2020 people
:P
Morgan is RIGHT!!!
Thx.
Morgan is 100% correct just took the test. aint cappin!!!
Me: Who is correct?
Morgan: On your left.
homework, DONE, time for Netflix (╯°□°）╯︵ ┻━┻)
this seems like it should be a SUPER popular website, why aren't people constantly talking
they changed the order of answers morgan is no longer right in June of 2021
Morgans answers are still correct for connexus
Thanks Morgan so now can we puck? 😂😂😂
How do you guys cheat and then do map testing and stuff
DONT LISTEN TO ANSWER QUEEN I GOT 2 ANSWERS WRONG!!!!!!!!!!
Follow me on tik tok @bennettbetz
IMBASAL
Well shes not 100% but at least she was right. Now if you want a 100% here are the two corrected answers.
D,B,A,C,C,B,B,D,A,A,D,B,C,D.
finish the song...(I SPY)
I'm just like DeRozan, if I shoot it, it goes in
I am in Cali just coastin', get 'em so wet they need coasters
I got a selfie with Oprah, I just ain't ever post it
And I'm in my happy place posted, I ain't frown since '06
Using Morgan's answers I got 12/14 I didn't go back over and look at the wrong ones but I got an 85.9% which is good enough for me
