Which part of a flower receives pollen during pollination?
stigma True, but Ill explain more... Pollen from the Stamen- (male reproductive parts of a flower) must land on the Pistil-(female reproductive parts of a flower) for fertilization to occur, and thats when the seed grows in the ovary. :)
Is non ohmic filament better than ohmic filament?
How can a filament give off heat without resistance?Another AnswerThe terms, 'ohmic' and 'non-ohmic' refer to whether or not a material obeys Ohm's Law. It has NOTHING to do with whether a filament is resistive or not!Ohmic materials obey Ohm's Law; non-ohmic materials do not.GSL incandescent lamps generally use a filament made of tungsten. If you were to apply a gradually-increasing voltage to that filament, and note the corresponding values of current and, then, plot the results in the form of a graph, you would find that the graph is a curve. For Ohm's Law to apply, the current must be proportional to voltage for variations in voltage and this is ONLY true for a straight-line graph. Tungsten, therefore, is non-ohmic and does not obey Ohm's Law.Tungsten is chosen for lamp filaments because it can withstand very high temperatures without failing. This is the main reason that it is chosen, NOT because it is non-ohmic.
Is it true that the organs make all the cells an organism?
In fact the opposite is true. Cellular reproduction is what causes other cells that make up Tissues, and therefore make up Organs from Tissues are what make cells.
Is it true when you push downward on earth to make a pole vault earth exerts an equal force on the pole?
True
Can you tell when there is a hurricane?
no you can make a gess but it might not be true

When were filament tubes invented?
The first hot filament diode tube was invented in 1904 by Fleming, the first hot filament triode tube was invented in 1907 by DeForest. However it was not until 1913 that it was determined that high vacuum was actually needed for efficient and reliable operation of these tubes. So true hot filament vacuum tubes were not made and used until 1913.
True or false 1 The two main parts of a pistil are the filament and anther 2 Asexual reproduction in plants is called vegetative pollination?
It is true that reproduction in plants is called vegetative pollination. This is how more pants come alone.
How do you make a wisk of true love come true?
you can't make it come true
Is the brightness of a light bulb determined by its filaments?
Though there is a bit more to the story than this, yes, it is generally true that the brightness of a light bulb, sometimes called a lamp, is a function of its filaments. For a given voltage of operation, a less resistive filament will draw more current, run hotter and will glow more brightly (be more incandescent). A heavier, more resistive filament will draw less current, get less hot, and not produce as much light (be less incandescent). The former will run "hotter" as well as brighter, and the filament won't last as long, though it will be more efficient. The latter will not be quite as bright or as efficient, but the filament will have a longer operating life, and will probably be more shock resistant. Lamp filaments are usually made of tungsten, and these filaments are coiled to reduce evaporation of the metal when that metal is white hot. There is a "balance" engineered into the lamp to make it run "hotter" and more brightly to be more efficient, yet limit current somewhat, limit filament evaporation and extend the life of the lamp. Eventually, enough of the filament evaporates away in normal operation to create a "hot spot" that quickly degrades, and the filament fails. A link can be found below to learn more.
Can you make true black out of the primary colours?
No, you can not make true black out of the primary colors.
True or false a three way light bulb has 3 filaments?
False. They contain two filaments which are first switched on independently of one another (the lowest two settings), then switched on simultaneously to produce the highest setting. For instance a bulb containing a 25 watt filament and a 50 watt filament will produce 25, 50 and 75 watts of light.

What if all your friends say guy likes you then does make it true?
No it doesn't make it true. It is gossip and the only way that it is true is when he tells you.
Particles that make up matter are in constant motion true or false?
True
Is it true that Graphs make relationships easier to understand.?
true
Is it true that your boyfriend will make you jealous?
no it's not true that your boyfriend will make you jealous. Because It won't happen.
