Carbohydrates contain carbon, hydrogen, and oxygen in the molar ratio 1:2:1. The empirical formula for carbohydrates is CH20. The monomers of carbohydrates of are sugars.
Answer:
The 'Mole'
Explanation:
In the International Systems of Units i.e. SI, mole is the unit for the measurement of the amount of substances, or in simple terms the number of microscopic molecules or particles in a given sample is measured in mole. It is denoted by the symbol 'mol'.
If in a given sample there are 1 mole particles or molecule then it means that the total number of particles or molecules in that sample is equal to the Avogadro's number and this number has a value of 
. Mole is used as a measurement unit for various types of microscopic particles like atoms, molecules, ions electrons.
Answer:
Behavioral isolation
Explanation:
The reproductive isolation refers to the mechanism which prevents the interbreeding between the organism. The mechanisms of reproductive isolation can be categorised into two types: The pre-zygotic and post-zygotic barriers.
The prezygotic isolation mechanisms are the behavioural, the habitat, mechanical and gametic isolation.
In the given question, the type of mechanism involved in the population of frog will be the "behavioural isolation" as the population of frog differ in their behaviour of mating ritual or mating calls which does not allow the frogs to mate.
Thus, Behavioral isolation is the correct answer.
