the formula we will sue is for calculating the surface area of a tube is: 2 x x x radius x length.

measure the radius (easiest way to do this is to measure the diameter (the distance across the opening of the tube) and divide in half). include units (cm or in)=
measure the length of the tube you used from top to bottom. include units (cm or in) =
let's simplify x as 3, and plug in your values. your equation becomes 2 x 3 x radius x length
using the equation in step 3, what is the surface area of your small intestine? units will be in unit squared (ex: cm^2 or in^2) )
large folds of your small intestine increase the surface area by three times.
the small folds, villi, increase the surface area further by another ten times. what is the final surface area of your small intestine?

Researchers determine that the biodiversity in a woodland region is declining. they identify two major threats to the region's biodiversity, a method to address each threat, and the expected outcome of each method. this information is shown in the table. threat method number of species that benefit number of years to see benefit habitat fragmentation reforestation 450 8 introduced prey species biological augmentation 150 2 which statement is an accurate explanation of the information in the table? a. biological augmentation would benefit only a few species because it is typically not very effective. b. biological augmentation would take less time to be effective because it targets the majority of prey species. c. reforestation would take the longest time to be effective because trees take several years to grow. d. reforestation would not benefit many species because most forest species live on the ground.
