O Ramji, bada dukh di na
Tere Lakhan ne bada dukh di na - 2
Sudh budh bisraayi meri neend churaayi
Mera mushkil kar diya jeena
Bada dukh di na
Tere Lakhan ne bada dukh di na
O Ramji, bada dukh di na
Voh deepak hai, main jalti hoon - 2
Voh hansta hai, main roti hoon
Mere pyaar ki kadar usse hogi magar
Mujhe zaher padega peena
Bada dukh di na, bada dukh
In catalase chemical reaction of hydrogen peroxide, the enzyme will change hydrogen peroxide into water and oxygen. In this case, hydrogen peroxide will be the substrate. If there is more substrate available, then the chance for the enzyme to bind to the substrate will be higher, thus the reaction speed will be higher in solution with higher hydrogen peroxide
Because freezing will often burst the cell walls and destroy tissue. The crystals of ice are very sharp and hard to control AFAIK. Note what happens to a banana or many types of fruit after you dethaw — it becomes all mushy and not of the same structure, fiber and cell form as before, like a bad beam up in Star Trek.
A constant is something that is kept the same throughout the course of a experiment. So I would guess C) because they are not doing anything special. If it’s not C then it is A. :)
