Explanation:
It correctly reads;
A group of students use a device to study the energy transfer during the chemical reaction between pieces of eggshell (calcium carbon) and vinegar (acetic acid). During the experiment they use the same mass of eggshell but the concentration of the vinegar varies, (1%, 3% and 5%). Answer:
1. Explain why the energy transfer is not the same between the three tests of the experiment.
2. Describe how the device could be modified so that it can MORE ACCURATELY measure the energy transfer in each reaction.
<span>Lakes and ponds are inland bodies of standing or slowly moving water. Although lakes and ponds cover only 2 percent of the world's land surface, they contain most of the world's fresh water. Individual lakes and ponds range in area from a few square meters to thousands of square kilometers. In general, ponds are smaller than lakes, though regional idiosyncrasies of naming abound—Henry David Thoreau's famous Walden Pond in Massachusetts has a surface area of 64 acres. Lakes and ponds are an important source of fresh water for human consumption and are inhabited by a diverse suite of organisms.</span>
Answer:
Lung
Explanation:
Lungs expand to pull oxygen into the body and contract to push it back out. The larynx is known as the voice box which is an air way passage to the lungs and a pharanx is membrane lined cavity behind the nose and mouth. Neither of these really expand or contact during inhalation so the answer is Lungs.
The correct answer is C) carboxysomes
Carboxysomes are polyhedral inclusion bodies that contain enzyme ribulose- 1,5-bisphosphate carboxylase/oxygenase (RuBisCO). This is responsible for the fixation of carbon dioxide in cyanobacteria. Carboxysomes have evolved as a consequence of the increase in oxygen concentration in the ancient atmosphere.
Thus, <em>carboxysomes are not energy reserves</em>, unlike another offered answers.
