I believe the correct answer is C. The other answers give outside information that doesn’t correlate with the promoted question.
Answer:
I guess the application method by hands is more harmful. As pesticides are some sort of chemical substances which are used to kill insects and other sort of pests in any kind of plant. And we also know that pesticides are chemical substances.So when pesticides are typically applied by hands it can damage your palm skin.After applying pesticides you wash your hands. But, Do you know that even after washing little amount of pesticides are left on your palm?? And by using that hands you cook food then eat it. Then, you will fall sick as well as your family members. So, isn't it harmful to apply pesticides by using your hands??
__Dry and Liquid Measurements__
Explanation:
Density is defined as a material per unit volume of the material.
The determination of the density of a liquid with an aerometer is based on the principle of Archimedes' law: "Any object that is immersed in a liquid will experience a lift which is equal to the weight of the liquid being moved".
The aerometer is in the form of a hollow cylinder, so that the aerometer can be immersed in the right position (the scale is immersed in liquid), then the aerometer is filled with Pb grains. The scale on the aerometer shows the density of the liquid, the smaller the density of the liquid, the deeper the aerometer will be. Therefore the aerometer scale shows an increasing number from top to bottom.
Air pollution permits, for sure, you don't have to pay for air polution to drive a truck, so why when you build and office.
