This investigation uses respirometry techniques to calculate the rate of oxygen consumption cellular respiration in germinating pea seeds. The effect of temperature and whether a seed has broken dormancy are quantified and graphed. The ideal gas law and its concepts are reviewed and applied. Basic Questions scientific practices What is the relationship between temperature, volume, and pressure?

How can repiration rates be measured using a respirometer?

How is respiration rate affected by temperature? How does the respiration rate of a germinating see differ from that of a dormant seed? Understand the relationships between temperature, pressure and volume. Background Each individual cell is responsible for the energy exchanges necessary to sustain its ordered structure.

Cells accomplish this task by breaking down nutrient molecules to generate ATP adenosine triphosphatewhich can then be used to run cellular processes that require energy. This process is called cellular respiration which requires nutrient molecules and oxygen.

Carbon dioxide and water are products of the series of reactions involved in cellular respiration. There are several methods of indirectly measuring the rate of cellular respiration in organisms. One method involves monitoring changes in temperature; since the process of respiration is exergonic produces heat.

Another method is to measure either the oxygen consumption or the carbon dioxide production. Respirometers are devices that measure these types of gas volume changes, and therefore provide information about the rate of cellular respiration.

In order to be able to use a respirometer, you will need to use the ideal gas law, which describes the relationship between temperature, pressure and volume. Oxygen gas is being consumed by the respiring cells and carbon dioxide gas is diffusing out of the cells.

The respirometer, therefore, has to be able to deal with two simultaneously changing gas volumes. This is accomplished by introducing potassium hydroxide into the device.

Any CO2 produced is immediately converted from a gas to a solid and is therefore no longer governed by gas laws. This allows the respirometer to measure only one variable, the consumption of oxygen gas by living cells.Kaspersky Lab (/ k æ ˈ s p ɜːr s k i /; Russian: Лаборатория Касперского, Laboratoriya Kasperskogo) is a multinational cybersecurity and anti-virus provider headquartered in Moscow, Russia and operated by a holding company in the United initiativeblog.com was founded in by Eugene Kaspersky, Natalya Kaspersky, and Alexey De-Monderik; Eugene Kaspersky is currently the CEO.

This simulation lets you explore various aspects of sampling distributions. When the simulation begins, a histogram of a normal distribution is displayed at the topic of the screen.

The probability value (p) is the probability that a deviation as great as or greater than each chi-square value would occur simply by chance. Many biologists agree that deviations having a chance probability greater than (5%) are not statistically significant.
