Easy answer: its too hot.

The deepest man made hole is Kola Superdeep Borehole. That was a Russian experiment to see how deep you could drill into earths crust, reaching down 12,262 meters. At that depth the temperature reached 180 °C. The scientists estimated that a 15,000 meters depth the temperature would reach 300 °C, and at that temperature the drill would cease to work and the project was stopped.

The producers in the ecosystem produce 25,000,000 kilocalories per year. How much energy is most likely available to the organis
Svetlanka [38]

Answer:

The correct answer is - 25,00,000 Kcal

Explanation:

The transfer of energy in the trophic level is move with each successive level of the trophic level of the pyramid. Energy transfer takes place in a manner that only 10% of the available energy move to the next level and the rest 90% of energy lost as heat and other processes.

So ith producers produce 25000000 Kcal than only 10 % of this will transfer to the next level or the second level of the pyramid

Producer ---->     primary consumer  ----> secondary consumer

100% energy      10% energy of producer     10% of primary consumer

So, the 10% of 25000000  ----->  2500000

Scalcet8 3. 8. 505. xp. a bacteria culture grows with a constant relative growth rate. after 2 hours there are 400 bacteria and
Papessa [141]

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.
