Identify each event as the result of mechanical weathering or chemical weathering.
kow [346]

<h3><u>The following events are identified as chemical weathering:</u></h3>
  • The minerals in a marble statue react with water to form acids and pores in the structure.
  • The rocks in a region are streaked orange after being exposed to repeated rains.

<em><u>Reason: </u></em>

When the weathering process occurs due to <em>chemical reaction</em>, then it is considered as chemical weathering.

In <em>the first case</em>, minerals of marble statue are <em>reacting</em> with water to cause weathering. In the <em>second case</em>, due to the <em>acidificaion reaction</em>, the change of the color has happened after exposure to the repeated rains.

<h3><u>The following events are identified as Mechanical weathering:</u></h3>
  • A piece of rock crumbles after being constantly thrashed by strong waves.
  • Industrial runoff forms cracks in a rocky structure in its path.

<em><u>Reason:</u></em>

When the rock is broken into simple pieces <em>without any chemical reaction </em>it is considered as mechanical weathering.

In the <em>first cause</em>, due to the <em>abrasion</em> caused by the strong waves, weathering has happened, in the <em>second case</em> industrial run off may be of varying temperature and thus may cause <em>heating or cooling</em> of the rock and causes weathering.

What are the end products of the electron transport chain?
solong [7]

The end products of electron transport chain are:

Water

Adenosine triphosphate (ATP)

Explanation:

  • Most of the free energy released during the oxidation of  glucose to CO₂ is retained in the reduced co-enzyme NADH and FADH₂, generated during the kreb's cycle.
  • Electron are released from these co-enzymes and are eventually transferred to an oxygen molecule to form water.
  • These transfer of electron from co-enzymes to oxygen molecule occurs through a series of protein complexes in the mitochondrial membrane. And the process is termed as Electron Transport Chain.
  • The large amount of free energy is released during the oxidation of NADH and FADH₂ is used in the production of ATP
