Answer: 1. increase the temperature from 27 degrees Celsius to 37 degrees Celsius
Explanation:
Generally, protease function optimally at temperature range of 55 to 60 degrees Celsius and at lower pH 5.0 to 5.5. Hence increase in temperature to 37 degrees Celsius will increase proteolysis.
The correct options are, frying an egg and burning candle.
Explanation :
Physical change : It is a change in which no new compounds are formed only changes occurs in size or state of substance. In this, there is no changes in the substance or compound.
Chemical change : It is a change in which a new compounds are formed by the chemical reaction. Changes occurs in their chemical composition and properties.
Frying an egg : It is a chemical change because a new substance is form by heating.
Burning a candle : It is chemical change because new substances are formed (carbon dioxide, water and heat) by burning.
Boiling alcohol : It is physical change because only changes in the state.
Melting and ice : It is a physical change because only changes in the state.
Making coffee : It is a physical change because no new substance is formed.
Therefore, frying an egg and burning candle are the example of chemical change.

Answer: sexual reproduction.
Explanation: In asexual reproduction there is no exchange of genetic characteristics due to the lack of fusion of gametes(haploid). Thus there is practically no variation in specie.
But in sexual reproduction there is exchange of genetic characteristics resulting from the fusion of haploid gametes hence there is variation and great diversity.
