Nolan and hunter are studying heat flow, so they design the following apparatus. the apparatus consists of two identical glass cylinders connected by a glass tube. during their experiment, nolan and hunter simultaneously pour hot water in the tank on the left and cold water in the tank on the right. then, they seal the tops of the cylinders and allow the water in the tanks to intermingle through the glass tube. to determine if heat is transferred, nolan wants to place his hands in each tank of water at the beginning and end of the experiment. hunter wants to use a thermometer to measure the temperature in each tank at the beginning and end of the experiment. how do nolan and hunter's proposed methods compare?

Nolan's method would allow him to make a descriptive observation. Hunter's method would allow him to include numbers in his data.

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.
