The shape of teeth is tightly connected with the food that animal eats.Examples:
• Herbivores (plant eaters) have flat teeth specialized for the grass chewing.
• Carnivores (flesh eaters) have long and sharp teeth for meat cutting.
• Omnivores (eat meat and plants) such as humans have various types of teeth with different functions.
There are four main types of teeth: incisors (at the front, sharp for cutting), canines ( to grip and tear food), premolars (flat surface for food crushing), molars (the biggest with flat biting surface, to chew).
Answer:
1,6 m / s ^ 2
Explanation:
De las leyes de Newton;
Fuerza = masa × aceleración
masa = 275 kg
Fuerza = 440 N
Aceleración = Fuerza / masa
Aceleración = 440N / 275Kg
Aceleración = 1,6 m / s ^ 2
