A system is a group of parts that can be considered one unit. Storm systems, ecosystems, and our bodies are natural systems. Car

s and houses are human-made systems. Choose an example of a system, and analyze the energy flow through the system. Describe in detail how energy enters the system, how energy changes form while in the system, and how energy leaves the system.

An ecosystem is simply a collection of communities of plants, animals, and microbes interacting together and with their physical environments.

<h3>Energy flow in an ecosystem</h3>

Energy enters the ecosystem through a group of living organisms known as the producers. the producers are mainly the green plants that are capable of photosynthesizing.

Photosynthesis converts solar radiation from the sun to chemical energy in green plants. Another group of organisms in the ecosystem, the primary consumers, feed directly on the producers and as such, are able to gain some energy from them.

The secondary consumers obtain their own energy by feeding on primary consumers. Tertiary consumers feed on the secondary consumers for their own energy and the food chain goes on and on.

Only about 10% of the available energy in one trophic level goes to the next trophic level. The rest of the energy is lost as heat to the surroundings. Thus, the producers have the highest energy in the ecosystem while organisms at the top of the food chain have the lowest energy.

State 3 functions of enzymes in the body
9966 [12]
<span>Enzymes have three main characteristics. First, they increase the rate of a natural chemical reaction. Secondly, they typically only react with one specific substrate or reactant, and thirdly, enzyme activity is regulated and controlled within the cell through several different means, including regulation by inhibitors and activators. It is possible to group enzymes into different categories, including oxidases, transferases, hydrolases, lyaes, isomerases and ligases. In naming enzymes, the "-ase" suffix is often appended to the name of the substrate molecule upon which which the enzyme reacts. For example, the enzyme sucrase catalyzes the transformation of the sugar sucrose in to glucose and fructose. In this case, the "sucr-" suffix represents the molecule upon which the sucrase enzyme reacts. Not all enzymes are named according to this convention.</span>

Which state of matter would be described as having highly energized, charged particles that move extremely fast
uranmaximum [27]
There are four states of matter, solid, liquid, gas and plasma. Their formation is as when solid is heated it converts into liquid, liquid on heating converts into gases and gases on heating converts into plasma.

Plasma:
           Plasma is the fourth state of matter. It is the highest energy state of matter.

Composition:
           Plasma is made up of negatively charged and positively charged particles.

Result:
           The answer to your question is Plasma.

Heat is transferred by conduction through a wall of thickness 0.87 m. What is the rate of heat transfer if the walls thermal con
erik [133]

Explanation:

The given data is as follows.

         Thickness (dx) = 0.87 m,       thermal conductivity (k) = 13 W/m-K

        Surface area (A) = 5 m^{2},       T_{1} = 14^{o}C

        T_{2} = 93^{o}C

According to Fourier's law,

                    Q = -kA \frac{dT}{dx}

Hence, putting the given values into the above formula as follows.

                      Q = -kA \frac{dT}{dx}

                          = -13 W/m-k \times 5 m^{2} \times \frac{(14 - 93)}{0.87 m}

                          = 5902.298 W

Therefore, we can conclude that the rate of heat transfer is 5902.298 W.
