Imagine that a radioactive isotope has a half-life of 2 years. A sample contains 1000 atoms of the radioactive isotope. Complete the following table to predict how many atoms of the radioactive isotope remain in the sample over time.

the leaf is an organ of a typical plant, and the main functions are to complete photosynthesis and allow the plant to exchange gas, just like how we have the respiratory system. leaves have the stomata, which collects maintains co2 and o2 levels. this is necessary for cell metabolism. the leaf also collects sunlight using chloroplasts. succinctly, leaves own a pivotal role in sustaining plant life.
