Answer:

The answer is Catalase.

Explanation:

Cells have enzymes that help regulate chemical reactions. Enzymes need a substrate to act on. In this reaction, catalase is the enzyme that acts on hydrogen peroxide, the substrate, and breaks it down to water and oxygen. In this way, catalase protects the cells from the potential oxidative damages of hydrogen peroxide.

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.

3. The prostate gland in men that secretes infection-fighting substance.
4. The immune system defenses and antibacterial substance in the mucous lining of the bladder eliminate many organisms.
5. The vagina of a healthy women, it is colonized by lactobacilli, a beneficial  microorganisms that maintain a highly acidic environment (low pH) that is hostile to other bacteria. It also produces hydrogen peroxide, which help eliminate bacteria and reduces the ability of Escherichia coli (E. coli) to adhere to vaginal cells that is the major bacterial culprit in urinary tract infection.
