Identify the factors that guided mendeleev while classifying the elements.

Mendeleev was the Russian chemist who is responsible for devising the periodic table of the elements. He arranged all the known elements of that time with the elements that were not yet discovered in a tabular format. His table even predicted the chemical properties and the atomic masses of the unknown elements. The two factors that guided Mendeleev in this classification of the elements are as follows:

1. Organization of the elements in increasing order of their atomic mass.

2. Making groups of the similar elements together.

answer; the above answer to the above statement is (true)

tsd is temerature dependent sex determination.

tsd: it is a type of environmental sex determination in which the temperature experienced during embryonic/ larval development (ambient temperature for development) determine the sex of the offspring.

crocodile displays the tsd where the ambient temperature of the developing egg determines the individual's sex. for example in the american alligator's eggs, incubation at 33 ºc produces mostly males, while incubation at 30 ºc produces mostly females. so if the american alligator's egg will get the ambient temperature (33 degree celcius)during embryonic development from egg, the offspring will be male and same for the female sex determination.
