Perilymph of scala vestibule; endolymph of cochlear duct; perilymph of scala tympani
Answer:
Mars
Explanation:
In the 1960s, humans set out to discover what the red planet has to teach us. Now, NASA is hoping to land the first humans on Mars by the 2030s. Mars has captivated humans since we first set eyes on it as a star-like object in the night sky.

It's been a while since I've studied this, but my answers would be:
13. 5730 years. The half-life of a substance is the amount of time it takes for half of it to decay, and, according to the graph, half of the substance remained at 5730 years.
14. 10740 years. According to the graph, only 25% of the carbon remained after 10740 years.
15. 15 atoms. According to the graph, only 12.5% of the carbon remained after 16110 years. 12.5% of 120 atoms is 15 atoms.
16. 1600 atoms. According to the graph, if a sample of carbon is 10740 years old, only 25% of it remains. To find the original amount, multiply the current amount by (100% / 25%), which equals 4. So, 4. 400 atoms * 4 = 1600 atoms is the original amount.
The mass of material is 26.6 Kg
Given:
Q = 4720 KJ
Change in Temperature (AT) = 65 K
Specific heat capacity of material (c) = 2730 J K Kg*K
The relation between Q, AT, c and m are related by following formula: Q=m* c*∆T,
Plugging value in heat formula:
4720KJ = m* 2730 J/Kg*K * 65K
4720KJ = m * 177450J/kg
Converting 177450 J/kg to Kg/KJ
177450 J/kg*1KJ/1000J = 177.450KJ/kg
Dividing both side by 177.450KJ/kg
4720KJ/177.450KJ/Kg = m*177.450KJ/Kg÷ 177.450KJ/Kg
Hence, the mass of material = 26.6 Kg
