Answer:
Left amount of Polonium-210 after 115 days will be 4.5927 microgram
Explanation:
We have given initial mass of Polonium-210 
Decay rate x= 0.502% = 0.00502
Time t = 115 days
We have to find the left amount of Polonium -210 after 115 days
We know that left amount is given by

So left amount of Polonium-210 after 115 days will be 4.5927 microgram
C) is definitely the bacterium!
A) look like a paramecium with it's flagela and vacuole
B) is a plant cell with chloroplasts
D) could be an animal cell, plant, or fungal since it has a nucleus

Answer;
D. Rift valley
Explanation;
-A divergent boundary also called the divergent plate boundary is a linear feature that exists between two tectonic plates that are moving away from each other. Most divergent plate boundaries are underwater (Iceland is an exception) and form submarine mountain ranges called oceanic spreading ridges.
-Divergent boundaries are areas where plates move away from each other, forming either mid-oceanic ridges or rift valleys.They are constructive boundaries. Convergent boundaries on the other hand are areas where plates move toward each other and collide.
