Why are organelles called "little organs"?

Chemistry

vitfil [10]3 years ago
7 0
Organelles are specialized structures that perform various jobs inside cells. The term literally means “little organs.” In the same way organs, such as the heart, liver, stomach, and kidneys, serve specific functions to keep an organism alive, organelles serve specific functions to keep a cell alive.

Explanation:

Magnesium reacts with dilute hydrochloric acid in a conical flask which is connected to an inverted measuring cylinder in a trough of water. The volume of hydrogen gas produced is measured over a few minutes, and the results are used to plot a graph

This is intended as a class practical. It is best if the students work in pairs because setting up and starting the experiment requires more than one pair of hands. One student can add the magnesium ribbon to the acid and stopper the flask, while the other starts the stopclock. During the experiment, one student can take the readings while the other records them. The experiment itself takes only a few minutes. But allow at least 30 minutes to give students time to set up, take readings and draw graph.

while the substance is a liquid at what temperature do the molecules of the substance have the greatest average kinetic energy ​
dalvyx [7]

The molecules of the liquid will be having the greatest average kinetic energy when the temperature of the liquid reaches its boiling point.

<u> Explanation: </u>

Average kinetic energy is the measure of kinetic energy exhibited by the molecules of any substance. It is directly proportionate to the temperature of the substance. According to kinetic molecular theory,

                           k=\frac{3 R T}{2 N_{A}}

As the molecules in solids are mostly closely packed, so they will attain the least kinetic energy of molecules in solid phase. Similarly, the molecules in liquid are slightly loosely packed and on increasing the temperature, the molecules will attain more energy to increase their neighbouring distances.

And when that temperature reaches the boiling point of that liquid substance, the molecules had attained the maximum amount of energy to increase its average kinetic energy to the maximum limit and transferring the liquid molecules to gaseous state.

As the molecules in gas phase are very loosely packed. The starting of the change in the state of molecules from liquid to gas phase on reaching the boiling point indicate the maximum average kinetic energy at that point.

Convert each of the potentials. The silver–silver chloride and calomel reference electrodes are saturated with KCl,KCl, resultin
joja [24]

Answer:

the potential with respect to a silver–silver chloride electrode is 0.715

Explanation:

the potential to a silver chloride electrode can be derived from  the question above by saying that

the potential with respect to a silver–silver chloride electrode? = 0.9120v  -  0.197 V

= 0.715

therefore, the potential with respect to a silver–silver chloride electrode is 0.715
