What structural component gives arteries the ability to passively adapt to changes in blood pressures that accompany the heartbe
Andrews [41]

Answer: elastic fibers

Explanation:

Elastic fibres are the essential durable component present in mammalian connective tissueand functions to provide proper pulmonary,  cardiovascular and intestinal system structure and function. Their structural function is to provide elastic recoil and resilience for the tissues.

Elastin fibers ahve two main including microfibrils and elastin containing fibrillin play a mechanical and structural role in the arteries, and their important function is to provide the tissues with resilience and elasticity.

Hence, elastic fibers helps arteries to adapt to changes in blood pressures that accompany the heartbeat.

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.
