The answer is A: convergent boundary zones. The various Japanese islands formed due to the subduction of the Philippine Sea Plate below the continental Amurian Plate and Okinawa Plate to the south, and subduction of the Pacific Plate under the Okhotsk Plate to the north. This occurred during the mid-Silurian to the Pleistocene . This explains why much of Japan is mountainous.

Alizarin yellow is a pH indicator that transitions from red to yellow when the pH falls from a value of 11 to below 10. Why is p
nydimaria [60]

Answer:

The correct answer is - acidic conditions wouldn't trigger a change in the color of Alizarin yellow.

Explanation:

The growth of E. coli generally occurs at neutral pH, however, its growth is normal at acidic conditions as well.  The change in the growth of  E. coli is not able to detect by alizarin.

The phenol red turns yellow in the presence of an acid, and the change in pH in an alkaline environment can be detected by the red color of phenol red. Growth of E.coli will grow in pH of 10-12 . But, very slowly. The color change in alizarin is also apparent at pH 10.2 to 12 only.

What is the most important barrier protecting the inner contents of an animal cell?
velikii [3]
The cell membrane. (It also could be cytoplasm because it supports the organelles. But I think it is the cell membrane because it says barrier, and the cell membrane is the cell's barrier between it and the outside of the cell.)

The cell membrane is the outer most layer of the animal cell. It is selectively permeable, so it lets good things in and keeps bad things out. It also helps larger things that the cell needs to get in such as glucose by the process of endocytosis.
