That would be 20 to the 50th power.
You’re making a protein consisting of 50 amino acid subunits. and u have 20 choices for each place. So 20^50.
Hope this helps
Converting the temperature, 295 K from Kelvin to Celsius scale:

Water has a boiling point of
and a melting point of 
When we compare water at two different temperatures,
we can say that water is in liquid form at both these temperatures as both of them are quite below the boiling temperature and above the melting temperature.
The temperature difference between water at the given two temperatures = 
Water at
is at a higher temperature and so is warmer than water at a lower temperature of
.
Individuals who are both born and raised in high altitudes will have their bodies re-establish equilibrium shift by producing more hemoglobin, which allows for more oxygen to be bound to the heme protein and thus cause an equilibrium shift to the right.
Yes, i expect to find an atom with 26 protons and mass number of 52, because if it has different number of neutrons it could be a type of isotope. As if there is different number of neutrons in an atom, they make an isotopes of that atom and if we add the number of neutrons and number of protons we will find the mass number of that atom.
