Answer:
Sequence
Explanation:
Physical properties of the proteins are foundation of biological function of them.
A protein molecule is made up from the long chain of the amino acids. Each amino acid is linked to its neighbor by covalent peptide bond. Thus, proteins are also called as polypeptides.
Each protein has unique sequence of the amino acids, exactly same from one molecule to next. Different proteins has its own particular sequence of amino acid. This sequence is responsible for folding and binding of the protein and also its physical characteristics.

Answer:
The concentration of sucrose will decrease.
Explanation:
The balloon contains 50% sucrose solution.
Diffusion is the net movement of the substance from the region of the higher concentration to the region of the lower concentration.
Given that the membrane is only permeable to water not sucrose. So, movement of sucrose will not take place. <u>When the balloon is placed in a beaker of water, by the process of diffusion, the water moves from beaker to balloon and thus, the balloon will expand and the concentration of sucrose solution will decrease.</u>
Answer:
10.80
Explanation:
As per the equation, let us calculate the mole ratio. N2+3H2→2NH3. As per the equation one mole of nitrogen reacts with 1 mol of hydrogen.
In terms of mass. 28.01 g of nitrogen needs 3 mol of hydrogen or 6.048 g of hydrogen.
We can set up the ratio;

Answer:
P= 138.6 atm or 1.4x10²
Explanation:
You will need to use PV=nRT to solve for P, pressure
Where the R constant is 0.08206 L atm mol^-1 K^-1
V is 1.2 L
T is temperature in kelvin, 273.15+25= 298.15
n is 6.8 mol
P*1.2=6.8*0.08206*298.15 ---> P*1.2=166.3700852 ---> P=166.3700852/1.2
P=138.6 atm
or 1.4x10²
