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>
The complete question is: Match the following; Disulfide BondsA. Covalent interactions not found in all proteins.Peptide BondsB. Covalent interactions found in all proteins.Long-range interactionsC. Non-covalent interaction formed primarily on the interior of water-soluble proteins.Hydrophobic coreD. Covalent or non-covalent interactions formed b/w amino acid far from each other in primary structure.
The answer
Disulfide Bonds (Covalent interactions not found in all proteins.)
Peptide Bonds (Covalent interactions found in all proteins.)
Long-range interactions (Covalent or non-covalent interactions formed b/w amino acid far from each other in primary structure.)
Hydrophobic core. (Non-covalent interaction formed primarily on the interior of water-soluble proteins.)

Answer:
Average atomic mass of potassium based on these relative abundances
Explanation:
The atomic mass of this element will be equal to the sum of product of its three isotopic masses and its fractional abundance
For isotope I -
Mass of Potassium-39 
amu
Fractional abundance of Potassium-39 
%
Mass of Potassium-40 
amu
Fractional abundance of Potassium-40 
%
Mass of Potassium-41 
amu
Fractional abundance of Potassium-41 
%
Average atomic mass of potassium based on these relative abundances
I feel the exact same way and what I would do is just try talking to them ,it may seem hard at first but try to start a conversation and maybe ask their friends about them or if they still like you
Answer : The molar concentration of solution is 
Explanation :
Using Beer-Lambert's law :
where,
A = absorbance of solution = 0.614
C = molar concentration of solution = ?
l = path length = 1.0 cm
= molar absorptivity coefficient = 
(assume)
Now put all the given values in the above formula, we get:
Therefore, the molar concentration of solution is
