The surface area of a sphere can be approximated as follows: Surface area =
41122;
where r is the radius of the sphere;
It is a constant that is roughly equal to 3.
Using the simple approximation above, calculate the surface area of a sphere
with a radius of 5 meters.
A. 500 m2
B. 900 m2
C. 3,600 m2
O D. 300 m2

What is turgor pressure, what causes it, and what does it do for a plant?

Johnny rode his bike to a friend's house 4 blocks down the street in his neighborhood. he immediately rode back home once he realized his friend was not able to play. what was his displacement for the total bike ride? how did you determine this? what could we use as a reference point to determine he was in motion during his bike ride? why can you use it as a reference point

One function of the poly-a tail on eukaryotic mrna sequences is to the mrna be transported from the nucleus to the cytoplasm. prokaryotic mrna also has a poly-a tail. choose the best explanation of the prokaryotic poly-a tail. a. prokaryotic poly-a tails are composed of a different molecular structure compared with eukaryotic poly-a tails. b. prokaryotic poly-a tails have the same functions as eukaryotic poly-a tails, because this process is highly conserved throughout different species. c. prokaryotic poly-a tails aren't important, because prokaryotes don't have nuclei. d. prokaryotic poly-a tails have other functions, because prokaryotes don't have nuclei.
