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.
The four main stages of Interphase are Gap 0, Gap 1, S phase and Gap 2. Interphase appears to be a resting stage in cell divisions but actually many activities or processes happens at this phase. Interphase generally lasts at least 12 to 24 hours in mammalian tissue.
Answer: Convection
Explanation: Cold water sinks because it is more dense than warm water.
Warm water rises because it is less dense than cold water.
Answer:
It's secreted into the extracellular fluids. Collects in the lymph fluid, the vascular blood fluid and eventually the excess is secreted via, urine, feces, lung respiratory exhalation gases, sweat, nasal and mouth, throat mucous and saliva, tears, etc.

There are four main types of tissue: muscle, epithelial, connective and nervous. Each is made of specialized cells that are grouped together according to structure and function. Muscle is found throughout the body and even includes organs such as the heart. Our outer layer of skin is epithelial tissue.
