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.

mario62 [17]

Answer: Osmosis

Explanation:

"Water makes up a large percentage of the body's cells. For a cell to remain in homeostasis, there must be a mechanism to control water changes in the cells. The movement of water from an area of high water concentration to an area of low water concentration is osmosis." Source, Quizlet. https://quizlet.com/350562884/cell-homeostasis-flash-cards/

In the year 100, Ptolemy introduced the geocentric model of the solar system. By the year 1542,
Alecsey [184]

Answer: Ptolemaic system, also called geocentric system or geocentric model, mathematical model of the universe formulated by the Alexandrian astronomer and mathematician Ptolemy about 150 CE and recorded by him in his Almagest and Planetary Hypotheses. The Ptolemaic system is a geocentric cosmology; that is, it starts by assuming that Earth is stationary and at the centre of the universe. The “natural” expectation for ancient societies was that the heavenly bodies (Sun, Moon, planets, and stars) must travel in uniform motion along the most “perfect” path possible, a circle. However, the paths of the Sun, Moon, and planets as observed from Earth are not circular. Ptolemy’s model explained this “imperfection” by postulating that the apparently irregular movements were a combination of several regular circular motions seen in perspective from a stationary Earth.

All rocks on Earth are eventually recycled into another type. In between the rock, types are different forms of materials, such
Oksanka [162]

Answer:

A) Energy from Earth’s hot interior produces magma which then cools

and crystallizes into igneous rock.

Explanation:

Energy from Earth’s hot interior causes extreme temperature and pressure which produces magma. This magma is present in liquid state that cools  and crystallizes into igneous rock. Metamorphic rocks are formed from other rocks due to high heat or pressure. Earth movements can cause rocks to go deeply into the earth which causes the rocks are heated and put under great pressure. Sedimentary rocks are formed when sediment is deposited due to air, ice, wind, gravity, or water flows carrying the particles in suspension.
