Based on the result in this experiment, the mobile phase rose up on the TLC plate then dragged the ink from the marked dot up along the TLC plate, which is the light pink pigment whose Rf was 0.98 had the greatest affinity to the mobile phase. Moreover, the pigment that was closer to the marked dot was more attracted to the stationary phase, which is the dark pink spot that had an Rf of 0.72 and had a greater affinity to the stationary phase.

Answer:

Elastomeric

Explanation:

An elastomer is a polymer whose main characteristic is elasticity and can even recover its shape after being deformed

The chemical composition of an elastomer is the grouping of thousands of molecules called monomers, which join together forming huge chains. These large chains of polymers are those that give elasticity since they are flexible and are intertwined in a very messy way.

When an elastomer is stretched, its molecules align, allowing many times to take a crystalline appearance. However, upon releasing the tension, it immediately returns to its original state of elastic disorder. The above distinguishes elastomers from plastic polymers.

In which zone would you expect to find the greatest abundance of marine organisms? middle intertidal zone supralittoral zone hig
serious [3.7K]

High littoral zone has greatest abundance of marine organisms.

<h3>What is High littoral zone?</h3>

The intertidal zone, also known as the "littoral zone," refers to the seashore that is covered during high tide and exposed during low tide, revealing a unique biome that survives under such fluctuating conditions.

<h3>Where are most marine organisms found?</h3>

The majority of ocean life can be found in coastal habitats on the continental shelf, despite the fact that this area accounts for only 7% of total ocean area. The majority of open ocean habitats are found in the deep ocean beyond the continental shelf. Species that live in the oceans and on the coasts can help to create new habitats.
