Answer:
Plant cells have cell walls
Explanation:
While both plants and animals are eukaryotic and multicellular, only plant cells have a cell wall.
Answer:
Agarose gel electrophoresis is the most suitable method for this analysis.
Explanation:
SDS-PAGE, sodium dodecyl sulfate polyacrylamide gel electrophoresis, is a procedure used for visualizing and separating proteins according to their molecular weight. The use of sodium dodecyl sulfate and polyacrylamide gel eliminates most of the influence of the tertiary structure and charge, and proteins are separated solely based on polypeptide chain length. So, if the student suspects that the protein sample is conformed of 4 subunits similar in molecular weight, SDS PAGE will likely not separate them.
On the other hand, an agarose gel electrophoresis can separate proteins based on their size AND charge, so, if you suspect that the proteins are not identical but similar in size, the charge factor can be important to separate them in an experiment.
Question 1) Photesphere
Question 2) core
Question 3) The suns gravity keeps them in place
Question 4) True
I'm not 100% about question 1 it's either photesphere or core, but I think Photesphere is correct
Answer:
Physical science is the study of the inorganic world. That is, it does not study living things.
