Answer : The length of protein will be, 36.8 A⁰
Explanation :
First we have to calculate the amino acid residue.
Given:
Length of single strand of protein = 27.0 kDa
Mean residue mass = 110 Da
Now we have to calculate the number of turns in protein.
As there are 3.6 amino acid per turn of the alpha-helix.
Now we have to calculate the length of the protein.
As, we know that the length of each turn = 0.54 A⁰
Thus, the length of protein will be, 36.8 A⁰
Answer:
Strontium
Explanation:
The atomic number of strontium is 38.
It has 38 electrons.
It is alkaline earth metal. It has two valance electrons.
Strontium loses its two electrons and form cation with +2 charge.
Electronic configuration;
Sr₃₈ = [Kr] 5s²
The valance electrons present in 5s are lost by strontium atom and form Sr⁺² cation.
it is yellowish-white metal.
It is highly reactive.
It form salt with halogens.e.g
Sr + Br₂ → SrBr₂
IT react with oxygen and form oxide.
2Sr + O₂ → 2SrO
this oxide form hydroxide when react with water,
SrO + H₂O → Sr(OH)₂
With nitrogen it produced nitride,
3Sr + N₂ → Sr₃N₂
With acid like HCl,
Sr + 2HCl → SrCl₂ + H₂
Because the cell membrane (plasmamembrane) is a membrane. Very simply put, you can think of it like a piece of cloth. If you have a piece of cloth, water can move through the small holes, but something large, like e.g. a piece of cheese cannot.

200 calories.
Explanation:
The (latent) heat of fusion of a material, is either one of:
1) the heat required to melt the material without
temperature change or
2) the heat removed from the material to freeze it
without temperature change.
For water this latent heat is 80 cal/g. Multiply this by
2.5 g to get 200 cal.
<u>Answer:</u> The volume of the container is 
<u>Explanation:</u>
To calculate the volume of water, we use the equation given by ideal gas, which is:
or,
where,
P = pressure of container = 200 kPa
V = volume of container = ? L
m = Given mass of water = 2.61 kg = 2610 g (Conversion factor: 1kg = 1000 g)
M = Molar mass of water = 18 g/mol
R = Gas constant = 
T = temperature of container = ![200^oC=[200+273]K=473K](https://tex.z-dn.net/?f=200%5EoC%3D%5B200%2B273%5DK%3D473K)
Putting values in above equation, we get:
Converting this into cubic meter, we use the conversion factor:
So, 
Hence, the volume of the container is
