Ineed asap what does the three-dimensional structure below most likely represent? a) the linear order of amino acids in a polypeptideb) the overall spatial arrangement of atoms of a polypeptidec) the three-dimensional structure that is created by folding a polypeptided) the arrangement of a number of polypeptides folded into a larger complex

D

Explanation:

There are four types of protein structures:

1. Primary Structure - linear order of amino acids in a polypeptide

2. Secondary Structure - folding of the amino acids into a repeated pattern due to hydrogen bonding of the polypeptide backbone

3. Tertiary Structure - the three dimensional structure created by a single polypeptide

4. Quaternary Structure - the arrangement of a number of polypeptide (two or more) folded into a larger complex.

The figure shows the Quaternary structure found in proteins, as is evident from the two different polypeptide chains (identified as light grey and a darker grey) that fold into a complex. This structure is often held together by van der waals forces, ionic bonds, hydrogen bonds, and in some cases, covalent bonds.

the formula for the conversion of temperature from degree celsius to kelvin is:

the sample of water at is converted to kelvin temperature by using the above formula as:

on comparing the two samples of water at or we can say that at and at respectively. the difference between the temperatures of two samples of water is:

hence, one can say that the sample of water at is greater than the sample of water at by .

answer is: nuclear fusion produces elements that are heavier than helium.

nuclei combine to form a heavier nucleus, releasing energy.  

for example, fusion of hydrogen atoms at the sun.  

this fusion nuclear reaction is in the inner core of the sun and hydrogen (atomic number 1) is conveted into helium (atomic number 2).  

the inner core is the central region of the sun and all solar energy is produced in the core by nuclear fusion.
