Where does air enter and leave our body?
Air enters our lungs so we can obtain oxygen to fuel our cells in our body. Air leaves the lungs because when oxygen enters the cells waiting in the lungs, the bi-product the cell makes when it absorbs the oxygen is carbon dioxide, [ which is exhaled from the lungs. ]

User: Sorry, but it does not answer my question.

Weegy: it eneter on our nose



User: What if I say that it enters or leaves our body through the lungs? Do you agree with me? Explain.

Weegy: yes i would agree here is the explanation :air enters our body by negative pressure breathing, wherein the diaphragm (muscle separating digestive and respiratory ..uhm... [ sections) contracts, thus increasing the space above (that is, the lung cavity) and so "pulling" the air into the lungs through the wind pipes and nostrils. ]

How do you say this in your own words: Yes, I think the Japanese were well-equipped to conquer Malaya and Singapore. Their army had well-trained and experienced soldiers who were very loyal and willing to die for Japan. The British also left behind a large amount of food, weapons, vehicles and fuel when they retreated from Malaya.
Weegy: I believe that the Japanese were indeed equipped well to conquer Malaya and Singapore since their army was well-trained and had loyal, experienced soldiers willing to die for Japan.

Why are frogs found usually in an environment with a water source?
Weegy: because are AMPHIBIANS User: SO!?! Weegy: Though habitat destruction affects all creatures, amphibians are especially vulnerable. When water sources dry up (for example, when wetlands are drained) many frogs find no where else to go. [ Deforestation of the rain forest has led to several frog species becoming endangered or threatened. Amphibians are also sensitive to environmental pollutants, meaning that a habitat doesn't have to be completely destroyed in order to harm the frog species that live there.

You are talking to yourself as a user and an expert? Do you have two windows open? And you rated yourself good? You might want to read the blog. This is considered cheating and is also the reason why so many of us are answering so many questons and not getting paid for them.
