Answer:
C. Radioactive dating
I know this because radioactive dating is done by examining the atomic particles found in an object. The atomic particles decay over time at a predictable rate. Scientists are able to measure the rate of decay to establish the age of the fossil, organism, and/or material.
The nutrient is phosphorus
<h3>The phosphorus cycle</h3>
Phosphorus cycles between living components of the earth (biosphere) and the soil (geosphere).
The element's reservoir is mainly the sediments of the ocean and rocks. Phosphorus gets into the soil by weathering of rocks.
Plants are able to pick the element up from the soil and animals are able to get their phosphorus by consuming plants.
When plants and animal die, their body decomposes and the phosphorus in them enters the soil.
Thus, the cycle being referred to in the illustration is the phosphorus cycle.

Answer:
Strong hydrologic connections among terrestrial and inland aquatic realms exist in both river floodplains and dryland ecosystems. In the evolution of river floodplains terrestrial vegetation diversifies inland aquatic habitats, providing a range of colonization options for different organisms
Explanation:
Answer:
The correct answer is the alarm reaction.
Explanation:
The alarm reaction or stage is the initial stage of the body's response to a stressful situation or stimuli, due to acquired physiological changes, such as high heart rate and increase in hormones activity.
In simple words, it is a reaction that body adapts in tough or fight or flight situation by pumping blood from the heart to arms and legs to fight or flight.
Thus, the correct answer is alarm reaction.
