The rods originally contain the fuel for nuclear reactions, which mean they are highly radioactive. The radiation they emit is very dangerous and harmful to all types of life; therefore, they must be handled with care and disposed of properly to minimize damage because of them.
Answer:
At the bottom of the sequence
Explanation:
According to the "principle of superposition of strata", the oldest rocks are formed at the bottom of sedimentary rock sequences.
The oldest rock layer would contain the the oldest fossil. Weathering, erosion, transportation and deposition would bring all sediments which includes rock materials and remains of living organisms to the basin where they would be lithified to form sedimentary rocks. This makes the oldest fossil to be at the bottom of the sequence. As time progresses, the fossil sequence would continue to accumulate and young upwards as the strata becomes relatively younger. Also, we know that fossils succeed one another in a definite manner.
This why relative dating of rocks can be possible.

Answer:
The photosynthetic organisms of the water can survive at a depth of 100 meters due to the presence of blue light.
Explanation:
There are two colors which are responsible for the process of photosynthesis. These two colors are red and blue. Red and blue light of solar radiation is absorbed and green light is reflected back by the green pigment called chlorophyll. So in the depth of 100 meters in the water, blue light is present so plants can make their own food during photosynthesis.
