Who discovered the islets of langerhans?
The person who discovered the pancreas cells is Paul Langerhans, a German biologist and pathologist. These cells called "Islets of Langerhans" are cells in the kidney that produce insulin, the blood suger level reducing hormone (i.e. if these don't work, you have diabetes). Occasionally, "Isles\Islets of Langerhans" are used as a form of comedy or nonsense place names.
Why do people grow and die?
Well, it depends on what you mean, like they can die of old age, when you die of old age it's because your system starts to shut down, and there aren't anymore blood cells to help you, because when you're younger your blood cells reproduce and grow and grow and grow ! But as you age older, your blood cells start to die can't produce.
What is the definition for energy transformation?
You keep on having energy but under another form. For instance, the light energy that you get from the sun, you may convert it into electricity by using photovoltaic cells or equivalent. Now, you haven't the heat from the sunlight, but you can use the generated electricity to produce heat again. You can transform energy on a direct way or the transformation shall follow some steps. Transformation of energy means that you can obtain determined kinds of energy which fits better for your purposes.
Why did Zacharias Janssen call cells cells?
The reason Zacharias Janssen called cells, cells is that when he looked at them they looked like actual cells like in jail or prision. hint cells
What is the name for cells in middle latitudes?
Ferrel cells are the name of the cells in the middle latitudes.
How can the power of the sun be converted?
Photo-voltaic cells absorb solar radiation energy and produce direct current output. A number of these cells arranged as an array can produce a useful amount of electric power.
How can you use the sun as a source of energy?
Through photovoltaic cells to produce electric current directly, or by direct absorption to heat water
Are dry cells a source of constant direct current voltage?
Yes.
What kind of current is produced by dry cells?
Simply, direct current (DC). The amount of current depends on the circuit it is used in.
What device was chemical energy in portable radios to produce sounds?
batteries or dry cells
Device that uses replishable substances to produce current?
fuel cells
What effect has the number of armature paths upon the current carrying ability of generator?
What effect has the number of armature paths upon the current-carrying ability of a generator?
How is solar energy extracted?
By using a special kind of cell called the photovoltaic cell. In the presence of light (not necessarily direct sunlight), these cells have the capacity to produce tiny amounts of electricity, which is why these cells are arranged in large banks to maximise current generation.
In the human pancreas acinar cells produce digestive enzymes and beta cells produce insulin because of what?
different parts of an individual;s DNA are used to direct the synthesis of different protein in different types of cells
Where do you find alternating and direct current?
alternative current Alternating current is produced by a type of generator called an alternator. Direct current is produces by a generator called a dynamo, or by rectifying altenating current, or solar panels, or cells and batteries.
Solar cells are used to turn sunlight into?
It comes out as direct-current electric power.
What produces a direct current?
The main source of direct current is the conversion of alternating current. Typically, AC is a sinusoidal waveform. Using what is called a full-wave rectifier, one can make all of the negative halves of the waveform positive. This means the waveform will have a series of humps in the positive region. This, however, is not usable DC yet; one must use a filter, or a series of filters, to smooth out the waveform until it is roughly linear and constant. The resultant signal is direct current. This is roughly what is contained within power adapters that you plug into your electronics from the AC wall outlet; they convert the AC signals to DC so the electronics can use the electricity.There are many reasons for doing it this way. Mainly, though, AC power is easier to produce and more efficient to transmit over long distance. DC, however, is often more usable, so the AC is converted after transmission.Another example of a DC source are solar panels, or photovoltaic cells, which produce electricity when hit by light.
