The answer is Bacteria
Prokaryotes are a microscopic single Celled organisms that has neither a distinct nucleus with a membrane nor other specialized organelles.
<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.
Molecular clocks use rates of mutation to measure evolutionary time.Mutations add up at a fairly constant rate in the DNA of species that evolved from a common ancestor. The more mutations that happened in each lineage, the greater is the differences between these lineages.
Vestibule portion of the nasal cavity is lined with sebaceous and sweat glands and numerous hair follicles.
<h3>What is vestibule?</h3>
- A vestibule is a tiny room that leads into a larger space, like a lobby, entrance hall, or hallway.
- It serves as a place to wait, block the view of the bigger space, stop heat loss, provide space for storing outside clothing, etc.
- A vestibule is something like the tiny space outside the main bank where you enter and where the ATM is stored.
- A vestibule is, for instance, the middle cavity of the inner ear that connects to the eardrum.
- A vestibule is a little opening or chamber at a canal's start.
- The urinary meatus (urethral opening) and the vaginal opening both open into the vulvar vestibule, which is a portion of the vulva between the labia minora.
