A population has 1000 individuals. Over a period of 1 year, 300 new individuals are born. Which equation shows how to calculate the birthrate of this population?

if you add everything up correctly you should get 69 i got this because 50 plus 19 is it

b. climate change will cause an increase in biodiversity of all ecosystems.

hope this

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.
