Answer:
Savanna
Explanation:
Lack of rainfall over a period of time may convert a temperate deciduous forest into a Savanna.
Grasslands are characterized by a domination of grasses rather than large shrubs or trees. Savanna is a grassland with a few scattered individual trees. Savannas are always found in areas that are quite hot. The annual rainfall in a typical savanna may range from about 76.2-101.6 cm. Some savanna regions may receive as low as 15.24 cm -25.4 cm of rain in a year, followed by a long period of drought when fires can occur.
<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
