describe each of the types of natural selection. include the role that each plays in increasing or decreasing variation within a population.

the organism adapts to the change in their environment by adapting by prefering a certain colour, trait, etc.

e.g. the black and white moth, there used to be alot of white moths because they were more harder to detect by the predators with lots of white trees which means there is a higher population of white moths rather than the black moths, but because of logging and pollution theres more black trees now and then the

white moths cant hide and camouflage with their white colour and so a decrease in their population and an increase in the black moths' population because now it is more efficient.

ask your friends for what they got then copy it down if you don't have any friends which is fine than google it or pay the teacher

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.
