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.
The correct answer is A) OH.
Answer: Marine environments provide the perfect habitat for these seagoing birds. They can be found in tropical and subtropical regions of the west coast of Central America, and northern South America.
Explanation:
Answer:
the concentration of the solute is lower inside the cell than outside it
Explanation:
This question depicts the process of ACTIVE TRANSPORT, which is the movement of a substance against concentration gradient, hence, requires energy input (ATP) to occur. In this case, transporting a solute from inside an animal cell to the extracellular fluid across the cell membrane always requires energy.
This is because the concentration of solute inside the cell is much lower than that of the extracellular fluid, hence, to move the solutes against this concentration gradient (low to high), energy in form of ATP is required.
Answer:
Triglycerides
Explanation:
Fat cells are also called Adipose cells. They are cells found all over the body and majorly functions in the storage of energy storing substances called TRIGLYCERIDES. Triglycerides are a type of lipids composed of a glycerol molecule and three fatty acids molecules.
Triglycerides, like every other lipid, are biomolecules that store a large amount of energy. However, they are stored in specialized cells called FAT OR ADIPOSE CELLS.
