Answer:
There are air filters to purify the air and water filters to clean the water. Well, the kidneys are like a filtering system, too. They contain nephrons, which filter waste from the blood in two stages. First, nephrons take waste as well as needed materials out of blood. Then, the materials the body needs (like water and glucose) are returned to the blood and wastes are eliminated from the body. This is one way the kidneys maintain homeostasis. The kidneys also regulate the amount of water in the body. The amount of water the kidneys return to the blood depends on the conditions inside and outside of the body. This is another way the excretory system maintains homeostasis. For example, you will make more urine on a cool day when you have drunk a lot of water than you will on a hot day when you've hardly had anything to drink.

Answer: No. He is not ambidextrous.
Explanation:
Being ambidextrous means that the kid should be able to use both of his hands and that there should not be a preference for one at the expense of the other one. In this case, the kid should not view a particular hand as the stronger hand.
With regards to the question, we are informed that the kid has the ability to write with his left hand but not his right but that he's able to use his right for other tasks because that's his strong hand. This shows that he is not ambidextrous as he can not write with his right hand. It shows the hands aren't being used equally.
