<h2>Protein folding </h2>
Explanation:
- Molecular chaperones bind to nascent and folding or misfolded proteins (through improperly exposed hydrophobic regions) and stabilize the polypeptide so it can fold into its native state
- They have the ability to prevent non-specific aggregation by binding to non-native proteins
- They play an important role in protecting cells from being damaged under environmental stress, such as extreme heat, poisoning, or mental stress
- Most common chaperones are heat shock proteins which are also called stress proteins
- The intracellular folding environment for proteins is chaotic because of the presence of other biomolecules, folding proteins, improper or fluctuating pH, heat, and other denaturants
- Chaperonins provide actual chambers for misfolded proteins to properly refold, segregating the protein from the chaotic cellular environment.
- The main key function of chaperonins is to assist in the folding of large protein molecules
Answer:
Correlation means that there is a relationship between two or more variables (such as ice cream consumption and crime), but this relationship does not necessarily imply cause and effect. When two variables are correlated, it simply means that as one variable changes, so does the other. We can measure correlation by calculating a statistic known as a correlation coefficient. A correlation coefficient is a number from -1 to +1 that indicates the strength and direction of the relationship between variables. The correlation coefficient is usually represented by the letter r.

Answer: Arenite
Explanation:
Arenite can be defined as the sedimentary clastic rock.
It is of the sand grain size.
It also comprises of matrix.
It is a metamorphosed sediment.
Arenite is formed by the erosion of the turbiditic re-deposition of the sands. It belongs to silicatic limestones.
Factors b,d,e,g are favorable to fossil formation and preservation.
<span>Hard bodies are more easily preserved; rivers and oceans deposit muds that keep bodies intact for long times after death; large population and long existence provide more opportunity for fossils to form; and a low oxygen content impedes decay and inhibits predators. </span>
<span>Factors a,c,f,h are unfavorable to fossil formation and preservation. </span>
<span>Thus, Organism E with 4 positive factors is number 1 -- has the top chance of forming a fossil. </span>
<span>Organism D with 4 negative factors would be number 5 -- has very little chance of forming fossils. </span>
<span>Of the other 3, all have soft bodies, so are "disadvantaged" compared to E...but </span>
<span>Organism A has no OTHER disadvantages, so is probably number 2 (second best fossil chance). </span>
<span>Organism C has ALMOST everything going against it -- despite its large population and long existence, it has no other positive factors -- so I'd put it at number 4 (second worst). </span>
<span>To summarize, my rankings are </span>
<span>1. E, 2. A, 3. B, 4. C, 5. D</span>
