How does coughing and sneezing help protect the respiratory system?
andriy [413]
Coughing and sneezing are reflexes of the body that prevent bacteria to further damage the organs inside the body. It helps in keeping the airways clear and in healing. The two sources or passages of these natural reflexes are the nose and the mouth.  
<span>
Inside the nose, there are nasal hairs present to filter the oxygen or air that we breathe in. These are called Cilia, these are protective mechanisms of the body that trap dirt that cannot pass through the respiratory system. Sneezing is a natural reflex that clears the nose passages from obstructions that might affect the lungs. Coughing is also a natural reflex that is generated by an irritation in the tonsils, this condition is commonly viral. The tonsils are responsible for protecting the passage of dirty air into the lungs.</span>

What is the major physical difference between old work monkeys and new world monkeys?
KIM [24]
Answer & Explanation:
- One of the biggest differences between these two groups of monkeys is their tails. On one hand, some species of New World monkeys possess prehensile tails, meaning they can use their tails to grasp or hold on to objects. Their tails can aid these monkeys in finding and eating food in the canopy as well as moving amongst the trees, as their tails provide extra support and balance.

- On the other hand, Old World monkeys all have tails, but they lack the ability to grasp objects. However, some Old World monkeys have pads called ischial callosities surrounding their hind region. As these monkeys tend to spend more time on the ground than their arboreal New World counterparts, these calloused areas of skin provide support when they sit to feed or rest.

I hope this helped! :)
