The correct option is B, that is, A FAMILY DONATES USED CLOTHING TO A SECOND HAND STORE.

Waste prevention has to do with the process and practice of reducing the amount of wastes products in order to produce a more sustainable environment. Waste prevention can also be called recycling. There are three types of waste prevention, these are primary, secondary and tertiary waste prevention / recycling.

Primary waste prevention refers to a situation in which the material to be disposed is not changed in anyway, before been reused. Such material can be given to friend or donated to a charity organization. The material is always used for the same purpose as the original use.

Secondary waste prevention involves some kind of modifications while tertiary waste prevention usually involves the use of chemicals and heat.

Answer:

Explanation:

In Punnett Square, you are bringing the letters on the top to the numbered squares, if that makes sense. It is to predict the genotype of offspring.

So square 1, on the left is A, and on the top is A, so it would be AA.

For square 2, on the left is a, and on the top is A, so it would be Aa.

For square 3, on the left is A, and on the top is A, so it is AA.

Square 4, your question, has a on the left, and A on the top, so it is Aa.

Hope it makes sense. You should probably watch a Punnett Square tutorial online or something for a full and more general explanation.
