What is the name of the spacecraft carrying samples from Bennu?
What kind of organism do you think the scientists found?
What is your reasoning for #4? (How did you determine what kind of organism it is?)

After analyzing Astrum primus, scientists have determined that the organism is made of 70% water.
![]()
If A. primus was placed into a saline solution of 30% salt, then the cell would in size because it is water.


What happens to the amount of carbon dioxide in the chamber over time?
What happens to the amount of oxygen in the chamber over time?
What would cause Astrum primus to die after 3 days in the chamber?

After analyzing Astrum chlorophyta, scientists have determined that the organism is made of 65% water.
![]()
If A. chlorophyta was placed into a solution of pure water, then the cell would in size because it is water.


What happens to the amount of oxygen in the light environment over time?
What happens to the amount of oxygen in the dark environment over time?
NASA scientists were curious to see survival patterns between the two new organisms and measured their survival rates. The graph below shows the survival rate of A. primus.

What happens to A. primus over time?
NASA scientists were curious to see survival patterns between the two new organisms and measured their survival rates. The graph below shows the survival rate of A. chlorophyta.

What happens to A. chlorophyta over time?
NASA scientists were curious to see survival patterns between the two new organisms and measured their survival rates. The graph below shows the survival rate of A. primus and
A. chlorophyta together.

What can you conclude about A. primus and A. chlorophyta?

Which of these best explains the results of the cell culture?
What should the doctor create to prevent others from contracting the illness?
Which of these best explains the results of the cell culture?
After further studies, the doctor determined that only humans can contract the disease, while A. primus and A. chlorophyta showed no signs of illness.
Which of these best explains why humans got sick, but not the other microorganisms that were on the asteroid sample?
