Answer:
 1.Vascular tube is used for vascular surgery and is very small in size with very small diameter and thickness,thus a little change in environment can also affect there result.
2.When testing for tension in the polymer it is very important to consider the strain rate as the increase in strain  can cause the material to  break.Therefore not only tension test but also strain test is required.

Answer:The timing of the cricket's depends on the temperature of the box
so the answer should be
timing of the cricket's chirps
Explanation:Hi!
There are a few types of variables in these types of experiments. They are independent, dependent, and controlled.
The independent is the one changed by the scientist, or in this case, the temperature. The controlled is the things that remain constant through every case, and the dependent is what is being observed, seeing if it changes through the altercation of the independent variable.
In this case, what is being observed is the timing of a cricket's chirps, because it is being watched whether or not temperature affects it.
Therefore, your answer is the third choice, or the timing of the cricket's chirps.
Hope this helped!

The answer is mRNA. Translation is the process of reading the code in mRNA in the ribosomes to make protein. The ribosome is the organelle responsible for making proteins. The mRNA is translated from the language of nucleic acids (nucleotides) to the language of proteins.
