Mars has extreme temperatures and lacks oxygen. these are some reasons why it would be difficult for most life from earth to survive on mars. scientists are studying certain organisms from earth that they think could be able to survive on mars. what kind of organisms are the scientists most likely studying?

answer:

the living organisms

step-by-step explanation:

because they are living what is the use of artificial items

c.   x=2.4cm

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.
