The experiment described above shows that THE EGG YOLK IS COMPOSED OF LIPIDS WHILE THE EGG WHITE DOES NOT HAVE LIPID COMPONENT.
The Sudan IV reagent dissolved into the egg yolk because lipids are present in the egg yolk. The reagent did not dissolve into the egg white because lipids are absent. Thus, the egg white does not contain lipids while the egg yolk contains lipids.
Answer:
A. The complementary shapes of an enzyme and a substrate
Explanation:
The Lock-and-Key model was made to show how an enzyme's active zone fits a substrate and how they bond together. It correlates just like a lock and a key; you have to have the correct-shaped key in order to open a lock. Same process of thought with the enzymes; you must have the same shape for both in order to bind together,
It would be the first choice :)
Because when replicating DNA, this process is called semi-conservative
Hope this helps :)
