A biologist began studying a population of bullfrogs. In 1998, she found that most of the male frogs croaked, but some did not. A bat species known to prey on male frogs migrated to the area in 2005. The
biologist returned to the area in 2008 and repeated population counts of male frogs. The table shows
her data

hello there,

guys i’m confused.

which rock will weather faster?

answer: b rock

substitution is the answer in this case

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.

answer; ///the above statement is (true);
