<h2>Part 1 Answer</h2>

<u>Limestone is a type of</u><u> sedimentary rock </u>

<h2>Explanation:</h2>

Limestone is a type of sedimentary rock which is composed mainly of skeletal parts of organisms living in water such as coral, forams and molluscs. The major materials of limestone are the minerals such as calcite and aragonite, which are different crystal forms of calcium carbonate (CaCO3). Limestone can turn into the metamorphic rock called marble if the right conditions occur.

<h2>Part 2 Answer:</h2>

<u>Over time limestone </u><u>can be deformed and crystallized</u>

<h2>Explanation:</h2>

Limestone and chalk are mostly made up of calcium carbonate. When acidic rainwater falls on limestone or chalk, these rocks may react with the rainwater, causing the rock to be weathered. With the passage of time if limestone has been squeezed and reshaped by temperature and pressure, its structure and composition changes to form a recrystallised limestone which is called  marble.

Chymotrypsin is used for:__________
8_murik_8 [283]

Chymotrypsin is used for polypeptide cleavage on the C side of Trp, Tyr or Phe.

<h3>What is Chymotrypsin?</h3>

Other proteins' aromatic C-terminal amino acids are hydrolyzed by it using an active serine residue. The protease enzyme chymotrypsin cleaves peptide chains at the C-terminal phenylalanine (F), tryptophan (W), and tyrosine (Y) residues.

Since the 1960s, chymotrypsin has been used in clinical settings as an oral proteolytic enzyme preparation. In comparison to a few other enzyme preparations currently on the market, it offers better inflammatory symptom relief and supports a quicker recovery from acute tissue injury.

The inactive monomeric protein chymotrypsinogen, which is produced and secreted by mammalian pancreas, is broken down into chymotrypsin by cleavage of several peptide bonds. As a result, three different polypeptide chains that make up the active enzyme were created.

What is an advantage of using nuclear power?
My name is Ann [436]
<span><span>Large nameplate capacity per plant, typically around 1 GW.
</span><span>Typically 90% capacity factor, maximizing output from the nameplate capacity.
</span><span>Small fuel transportation volumes as the fissionable material just isn't that big or heavy compared to equivalent fossil fuel BTU sources.
</span><span>Low CO2 per MWH on a full life cycle basis. ~12 grams which is only slightly more than wind / solar.
This is a reason nuclear is a much better source for one of the major pressing problems of today than fossil fuels: global warming.</span>No particulate matter pollution.No sulfur dioxide or other chemical pollution.<span>Low fatalities per TWH. 
Nuclear is higher than renewables according to current statistics, but much, much lower than fossil fuel generation.</span></span>

Nuclear power generates lots of clean, stable energy.

Kidney is a structure that is located toward the dorsal side of the body, lateral and superior to the hamstring but inferior to the heart.

The kidneys are a pair of bean shaped organs that are located at the downward part of the rib cage. The body of humans consists of two kidneys one kidney on each side of the spine and they're responsible for the filtering of excess water, waste products, and other impurities out of the human body.

maksim [4K]
The correct answer is speciation.
Speciation is the term that describes the evolutionary process causing populations to evolve into different species. There are four different types of speciation: allopatric, peripatric, parapatric and sympatric. In this case, the process described is an allopatric speciation, the most common of these four types. Allopatric speciation happens when populations are geographically separated, an event that obstructs the gene flow. Since the gene flow stops, the populations evolve in response to the different environments that they live in.
