What are the effect of a greater number of cysteine amino acids on the stability of the proteins?

Explanation:

Cysteine is a naturally occuring amino acid and it is exist in L-form abundantly .Cysteine involve in formation of sulfhydril group which is very reactive . Cysteine easily oxidised to form dimer i.e., known as Cystine . Cystine is very important to analyse the primary structure of proteins , effects while changing in secondary structure and stablization of tertiary and quaternary structure . Cysteine play very important role in three dimensional conformation of protein molecule and provide stablity . Disulfide bridge present between two cysteine are responsible for the formation of the loops of backbone and disulfide bridge also provide the stability to  loop of various proteins molecule . Quaternary structure mainly possible because of cysteine , here disulfide bridge of cysteine cause the linkage of various seprated polypeptides . In quaternary structure of various polypeptide chains are joinded together by interchain disulfide bridge . These interchains of disulfide bridge also provide stability of quaternary structure of proteins . The present of greater number of cysteine amino acids enhance the stablity of proteins molecules .

c is the answer to this question. altitude affects the weather because air molecules evaporate.

the circled areas are referred to   as sunspots.   the sunspots are cooler than the   surrounding area.

sunspots are temporary phenomena on the photosphere of the sun that appear visibly as dark spots compared to surrounding regions. they correspond to concentrations of magnetic field flux that inhibit convection and result in reduced surface temperature compared to the surrounding photosphere.
