If you choose to wear loose clothing, large or dangling jewelry, or contact lenses to lab, which of the following statements best represents how you should proceed?
a. all of these statements are reasonable compromises if you must wear these items to lab, but the best and safest practice is to leave them at home and dress for lab intentionally.
b. make sure to wear your goggles securely over your contact lenses and check with your lab manual and ta to be sure you will not be working with any volatile or fume-producing reagents.
c. make sure none of the jewelry will catch on your clothing or accidentally cut your gloves, and don't wear anything too valuable.
d. make sure all loose clothing or jewelry can be confined by the lab coat

Option A. All of these statements are reasonable compromises if you MUST wear these items to lab, but the best and safest practice is to leave them at home and dress for lab intentionally.

Explanation: in the lab., good safety practice is best rather than assumed safety.

water   molecules stay close to each other through cohesion, the collective action of hydrogen bonds between water molecules. cohesion plants draw water upwards from the root through the stem's transport tubes (xylem) to the leaf. this transport occurs even in large trees and against gravity. transpiration, evaporation of water from plant leaves, creates a tension on water molecules being pulled up from the stem and roots.

water also has high (the attraction of one substance to another) properties because of its polar nature. adhesion of water molecules to plant cell walls counteract gravity while water is transported from roots to leaves.

water exhibits a very high surface tension when compared to other liquids. surface tension is a property of a liquid that holds the surface together and allows it to resist an external force. by capillary action, the water forms concave menisci inside the pores. the high surface tension of water pulls the concavity outwards, generating enough force to lift water from the roots to the leaves of plants.

thus, cohesion, along with adhesion and surface tension creates a capillary action that keeps water molecules interacting and moving through the plants out to the leaf cells.

therefore, option d) is the correct answer.
