Breaking chemical bonds is typically an endothermic process, which means energy must be added (it must pull in energy)
Breaking of chemical bonds is always endothermic meaning it wants energy, so it takes energy from its surroundings and sucks it in. Think of 'endo' as inside. The chemical bonds want energy inside of it so it can break.
Forming of chemical bonds is exothermic, meaning it releases energy into its surroundings. Think of 'exo' as outside, or exterior, it releases its energy outside of itself.
I hope that makes some kind of sense :)
The most appropriate answer is A !!
In biology, cell theory is a scientific theory which describes the properties of cells. These cells are the basic unit of structure in all organisms and also the basic unit of reproduction.<span>The cell theory states that: All living organisms are composed of cells. Multicellular organisms (example: humans) are composed of many cells while unicellular organisms (example: bacteria) are composed of only one cell. Cells are the basic unit of structure in all organisms.</span>
The statement above is FALSE. In the scenario given above the doctor is working at the organ level. This is because, he is working with lung which is an organ that participates in breathing. The lung is an organ because it is made up of different tissues which are in turn made up of different cells.
Working at the cellular level involve working with cells. For instance, when a microbiologist is growing a cell in a culture, he is working at a cellular level.

<h3>What are reptiles?</h3>
Reptiles are the animals in the class Reptilia, a paraphyletic grouping comprising all sauropsids except birds. Living reptiles comprise turtles, crocodilians, squamates and rhynchocephalians.
The marine iguana, also known as the sea iguana, saltwater iguana, or Galápagos marine iguana, is a type of iguana that can only be found in the Galapagos Islands. It is a marine reptile that can forage in the sea for algae, which accounts for nearly all of its diet, making it unique among modern lizards.
Turtles are a type of reptile known as a Testudine, and they have a shell made primarily of their ribs. The Pleurodira and Cryptodira groups of modern turtles are distinguished by the way their heads retract.
