The manufacture of cell phones involve the use of several rare minerals that are primarily found in the Congo Basin of Africa. The mining of these has led to habitat destruction of endangered species and the death of millions due to political conflict. What is the most practical action to be taken in response to these facts?

A) Cell phones should be recycled so rare minerals can be recovered.
B) Mining should be monitored by the U. N. to minimize this destruction.
C) We should continue using older models of cell phones as long as possible.
D) Cell phones should be manufactured using more readily available materials.

answer: c. two haploid cells

explanation:

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.
