Being a Florida resident, I hear on the news constantly, Nasa is going to try to launch tomorrow, nope it's suspended, etc. My question is stated, but also I want to understand it's purpose. I'm aware of individual experiments, but how do they have any substantial progress on health issues or science issues? Did we just develop NASA to remain competitive with Russia? I have no knowledge of this issue, that's why I'm genuinely inquiring about it.

My aunt recently passed away and she was cremated. How does that process work? I have heard that the bodies are stacked up and it takes months in some places. I have also heard that the bodies are crushed prior to cremation. Is any of that true? How does it actualy work?

Solve for the equation.

-x + 6 - 5x = 14 - 2r

2(2x + 3) = -6(x + 9)

7 - (-4t) = 4t - 14 - 21t

and 1 more

-3/4x + 5 = 1/4x - 3

Thx

Assume you inocluated 100 facultatively anaerobic cells onto a nutrient agar and incubated the plate aerobically. You then inoculated 100 cells of the same species onto nutrient agar and incubated the second plant anaerobically. After incubation for 24 hours, you should have:
A. more colonies on the aerobic plate
B. more colonies on the anaerobic plate
C. the same number of colonies on both plates

the answer is C but i don't know why. I would think its A.

we did a stoichiometric experiment with CuSO4 (copper sulfate). so what would happen to the percent yeild if 1)the product was washed with water instead of acetone,2) not all the acetone was removed when we dried the product, 3) the beaker was not rinsed with the additional 5 mL of ethanol, 4) more then 10mL of water was used to dissolve the anhydrous copper sulfate

The range of a projectile depends not only on v0 and θ0 but also on the value g of the free-fall acceleration, which varies from place to place. In 1936, Jesse Owens established a world's running broad jump record of 8.09 m at the Olympic Games at Berlin (g = 9.8128 m/s2)) Assuming the same values of v0 and θ0, by how much would his record have differed ( in cm) if he had competed instead in 1956 at Melbourne (g = 9.7999 m/s2)?
