What is the length of filament of the stamen with respect to the style on the pistil in wind pollinated flower?
In wind-pollinated flowers, the filament of the stamen is usually longer than the style on the pistil. This is to ensure that the anthers, which are located at the top of the stamen, are well-exposed to the wind for efficient pollen dispersal. The style, on the other hand, does not need to be as long because wind pollination does not require precision in pollen transfer.

Why is the filament used in bulbs thin and long?
The filament in light bulbs is thin and long to increase its resistance, which in turn causes it to heat up and produce light when electricity passes through it. The length and thinness of the filament also help to ensure an even distribution of heat, preventing it from melting too quickly.
What happens to the resistance of a filament if it is replaced by a thicker wire?
If a filament is replaced by a thicker wire, the resistance of the circuit will decrease. Thicker wires have lower resistance because they offer less resistance to the flow of electric current compared to thinner wires of the same material and length.
What happens to the current in a filament is replaced by a longer wire?
If a longer wire is used to replace the filament, the resistance in the circuit will increase due to the longer length of the wire. This increase in resistance will cause a decrease in current flowing through the circuit, which can affect the overall performance of the system.
The thin filaments of a sarcomere consist of?
The length of the thick filament is the A band. The A band contains both thick and thin filament because they are overlapping each other. The H band is thick filament only, however, it only covers a portion of width of the thick filament.
What happens to the resistance of a filament if it is replaced by a shorter wire?
If a filament is replaced by a shorter wire, the resistance will decrease. Resistance is directly proportional to the length of the wire, so a shorter wire will have lower resistance. This is because there is less material for the electrons to travel through, resulting in less opposition to their flow.
What are the characteristics of petal in insect pollinated flower?
Large, brightly coloured, may have additional markings in UV that we cannot see but insects can. The flower may be very deep so only insects with the correct tongue length can get to their nectar, and their pollen is only transferred to flowers of their own species.
Is jute a staple or a filament?
Jute is classified as a staple fiber. This means that instead of being one continuous length (filament), jute fibers are short in length and are spun or twisted together to form yarns for weaving.
What is the length of a flower's stem?
The Leangth of a flower stem us 5 in.
What is the length of the stamen on a passion flower?
Depends on the species of passion flower, but normally between 1.5 and 2 cm in length
Element of electric heaters and filament lamp are made of high resistivity materials this is done to the filament length?
Not too sure bout it babe. Wish I knew the answer. Will get back to you if I do, yea mate?
What filament is thicker a 60-W or a 100-W bulb of the same length?
I'm pretty sure the filament of a 60-W bulb is thicker, since there is less resistance through a thicker filament, so less light and heat would be generated.
Is tencel a staple or filament fiber?
Tencel is a staple fibre. That is it is cut into staple lengths during production so that it can be processed into yarns and nonwoven fabrics on conventional textile processing machinery. The cut lengths are similar in length to cotton or to wool. Continuous filament Tencel yarns are not produced but in theory could be. In a filament yarn all of the fibres in the yarn have the same length as the piece of yarn.
What is the manufacturing difference for 12 V DC and 24 V DC bulb?
The filament will have a different resistance, suitable for the voltage used and the power output of the lamp. The filament will be a different length and thickness to achieve this.
How does the growth of filament occurs in spirogyra?
Filamentous growth in Spirogyra occurs through the repeated divisions of its cylindrical cells, resulting in the elongation of the filament. Each cell contains a single spiral chloroplast that enables photosynthesis. As the cells divide, the filament grows in length, maintaining its characteristic spiral structure.
Is it appropriate to have flower girls in tea length dresses and bridesmaids in full length?
Yes - totally appropriate.
If the tungsten filament of a lamp has a cross-sectional are of 5x10-9 m2 how long must it be have a resistance of 120 ohms at 20 degrees Celsius?
To find the length of the tungsten filament, you can use the formula: R = ρ * (L/A) Where R is the resistance (120 ohms), ρ is the resistivity of tungsten, A is the cross-sectional area (5x10^-9 m^2), and L is the length of the filament. Rearranging the formula to solve for L gives: L = R * A / ρ Given the resistivity of tungsten at 20 degrees Celsius, you can calculate the length of the filament.
How do you determine the area of a rectangular flower bed?
You multiply the length by the width.
