Explanation

Intermediate filaments have a diameter of about 10 nm,

Which is intermediate between the diameters of the two other principal elements of the cytoskeleton:

1. actin filaments (about 7 nm) 
2. microtubules (about 25 nm).

Additional informational:

The intermediate filaments are not directly involved in cell movements.

They appear to play a structural role by providing mechanical strength to cells and tissues.

Explanation

Near Schools Colleges, Hospitals, and mosques maximum Speed limit is 40km/h.

Additional information

Urban arterial roads generally have an 80 km/h limit.

The G.T. Road's speed limit is 100 kilometres per hour 

Explanation

To find the approximate distance from the lens to the image in a camera with a focal length of 6 centimeters, we can use the lens formula:

1/focal length = 1/object distance + 1/image distance

Given information:

- Focal length = 6 centimeters

In this case, the distant scene is being photographed, so we can assume that the object's distance is very large, approaching infinity.

As a result, we can approximate the lens formula as:

1/focal length ≈ 1/image distance

Simplifying the equation:

1/6 cm ≈ 1/image distance

Cross-multiplying:

image distance ≈ 6 cm

Therefore, the distance from the lens to the image is approximately 6 centimeters.

Explanation

 by using light of a shorter wavelength in a double-slit interference experiment, the widths of the fringes in the resulting diffraction pattern on the screen would increase.

Concept and Explanation:

Wavelength of light:

The width of the fringes in a double-slit interference pattern is directly related to the wavelength of the light used.

When light with a shorter wavelength, such as blue or violet light, is used, the fringes in the resulting diffraction pattern will be wider compared to using light with a longer wavelength, such as red light.

This phenomenon can be explained by the diffraction of light waves.

Shorter wavelengths diffract more around obstacles and result in broader interference patterns on the screen.

Explanation

Protonephridia or flame cells are the excretory structures in Platyhelminthes (Flatworms, e.g., Planaria), rotifers, some annelids

Explanation

Stearic acid ( STEER-ik, stee-ARR-ik) is a saturated fatty acid with an 18-carbon chain.

The IUPAC name is octadecanoic acid.

Explanation

The OP-amp can amplify both a.c. and d.c. signals.

An integrated circuit known as an operational amplifier (Op-Amp) amplifies the difference between two input voltages and generates a single output.

Explanation

The rate of evaporation is directly proportional to temperature.

Thus, the rate of evaporation is higher on a warm day than a cold day having low temperature and clothes dry faster on a warm day.

Explanation

In honey bees, sex determination is based on the number of chromosomes an individual receives.

By parthenogenesis, an offspring created by the combination of a sperm and an egg develops as a female (queen or worker)

while an unfertilized egg develops as a male (drone).
