Water and sunlight and vitamin d h20
Answer:
because there is not a lot of anything in that layer so anything that comes into it creates a reaction, heat
Explanation:
Because there are relatively few molecules and atoms in the thermosphere, even absorbing small amounts of solar energy can significantly increase the air temperature, making the thermosphere the hottest layer in the atmosphere"
The initial population was 80
<h3>
Solution ;</h3>
The bacteria culture has a constant growth rate.
So, N(t) = No*(1 + r)^t
Solution :
400 = No*(1 + r)^2
50000 = No*(1 + r)^8
(1 + r)^6 = 125
=> 1 + r = 2.2360
No = 400÷(1 + r)^2 = 80
Hence, now we can conclude that the initial number of the bacterial culture was 80.
