Define 4 types of teeth(incisors,canines, premolars and molars)
vredina [299]
  • Incisors: Incisors are your two front teeth and the teeth on either side of them on the top and bottom of the mouth. Incisors are designed like tiny chisels with flat, moderately sharp ends. These teeth are formed to cut and chop food.

  • Canines: The pointy teeth beside your incisors are your canine teeth. You have a total of four canine teeth—two on the top and two on the bottom. These teeth are also designed to be sharp for tearing food.

  • Premolars (bicuspids): Premolars or bicuspid teeth are located just beyond the canine teeth toward the back of the mouth. You have eight in total—four on the top and four on the bottom.Premolars are bigger, stronger, and have ridges designed for crushing and grinding food.

  • Molars: In the very back of your mouth are the molars. You have eight molars—four on top and four on the bottom. Molars are your strongest set of teeth, formed with more width and ridges than the premolars. The molars are also designed for chewing and grinding, as well as thorough mashing of your food prior to swallowing. The molars generally do not surface until the ages of 6 to 12.

FinnZ [79.3K]

Answer:

b. grasshopper effect

Explanation:

Persistent Organic Pollutants or POPs are organic chemicals that cause a lot of damage to environment and living beings. They are generally industrial chemicals or pesticides for example, DDT. They are toxic and not degraded easily. They tend to get accumulated in living tissues and increase in concentration as we move upwards in a food chain.

When POPs are transported to areas far from their original site, the phenomena is called as grasshopper effect. They are carried by wind in atmosphere and finally settle down on land from where they evaporate again to enter the atmosphere. Thus, the cycle continues. Eventually, they can reach to an area thousands of kilometers away from their original source.
