Let us assume that the trait of orange beaks is dominant in ducks, with yellow beaks being recessive. Parent duck #1 genotype: Yy
Parent duck #2 genotype: Yy

3. What is the probability that their offspring will have a yellow beak?

climate change and pollution

when it is at an intermediate population density

. the sierra madre fault zone of southern california

. the san andreas fault california

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.
