Cigarettes no matter whether they come with a filter or not are injurious to health. Cigarettes contain tobacco leaves These tobacco leaves are rich in nicotine. When a cigarette is burned, it gives off the nicotine vapour, carbon dioxide, carbon monoxide, vapours of heavy elements like lead and the carbon soot in the form of tar. The filter present at the end of the cigarette mostly blocks the tar and condenses the harmful vapours of the heavy elements like the lead inside it. When Rita smokes a filtered cigarette, she gets a relatively high concentration of nicotine-rich vapour in the smoke. Though a unfiltered cigarette will have the highest concentration of nicotine.

"1. it should be, it has been for about 20 years, and it's really not much different in the end than breeding animals to have particular traits. there are always concerns about genetically engineered animals/plants affecting the environment in unexpected negative ways, but i can't think of an example where the fears didn't turn out to be baseless.

first, as you point out, it would be a great advance in pharmacology, to be able to tailor drugs and their doses to me. the pros involve better medical treatment. the cons involve privacy issues like insurance companies denying coverage to people with genetic risk factors. looking at dna markers wouldn't affect the frequency of genetic diseases, but it would allow detection of them earlier. and ok, actually i suppose that if people used this information to avoid having children with genetic diseases, some might decrease in frequency."

when the displaced particles are perpendicular to the direction the wave travels, is called a transverse wave, whereas in longitudinal wave the displace practices are parallel to the direction of the wave.

in the given image:

first image shows - longitudinal wave

second image shows - transverse wave

third image shows - longitudinal wave

fourth image shows - longitudinal wave
