<u>Second Part of the question:</u> What is the name of the aluminum ion?
<u>
</u>Answer : <u>Al+3</u>
Explanation: <em>An aluminum ion has a charge of +3. It is not a neutral atom. It has a + charge, the electrons must have been taken away (electrons have a negative charge). Since the atomic number is 13, the number of protons is thirteen. In a neutral atom, there would be thirteen electrons. You take away 3. There is 10 electrons in Aluminum Ion. </em>

Animals store most of their excess energy reserves as fat within the body. Whenever carbohydrates are not available, this stored fat provides the required energy. Fat is a very important part of the diet as it helps to maintain the body temperature. Fats also help to absorb certain vitamins like A, D, E and K.These vitamins are highly essential for our body and is present in our daily diet that we eat. These vitamins are also called fat soluble vitamins. It should also be kept in mind that there are good fats as well as bad fats.

P=G+E
The litters can inherit the trait of running, having a good vigour and ability to win agility competition but when the environment do not allow this trait to be expressed the trait can be masked i. e may not find expression.
The environment ensure that this litters are been taught the rudiment of agility competition to ensure they win if they are not been taught, they many not know they have the ability to win and will not be different from other dogs.
The training is what brings out the potential in them that can later be seen and expressed in the competition.
