Create a Plan of Action
Construct a practical plan of action for reducing your ecological footprint. This
should include changes that you could realistically make in your lifestyle. You don't
want the changes that you make to be so different from your current lifestyle that
there is no way you would ever make them.
Some examples might include: starting to recycle, turning the lights off when you
leave a room, reducing the time that you spend in the shower each day by 10%,
buying products in recycled containers, etc.
Your plan of action should include a minimum of 10 small changes that you could
make in your everyday life.

humans, along with other animals and plants, have linear chromosomes that are arranged in pairs within the nucleus of the cell. the only human cells that do not contain pairs of chromosomes are reproductive cells, or gametes, which carry just one copy of each chromosome.

a and c are the answeres

answer: zinc is the substance which has a volume of 1.38 .

density is defined as the mass of an object per unit volume.

it can be calculated by dividing mass of a substance by its volume i.e.

si unit of density is kg per cubic meter and cgs unit of the same is gram per cubic centimeter.

now from the given data volume can be calculated by the formula .

hence, the volume of aluminium will be = which comes out to be 1.703 .

similarly, volume of zinc, chromium, and nickel will be 1.378 , 0.869 , and 0.356 respectively.
