Astudent is investigating the question "which increases a person's breathing rate more after three minutes, lifting five-pound
weights or lifting ten-pound weights? she designs an experiment to test the question. which statement most likely describes
the dependent variable in her experiment?
o the breathing rate is the dependent variable because it can be affected by varying weights.
o she cannot measure the dependent variable until she finishes the experiment.
the time of exercising is the dependent variable because it can be measured.
o the five- and ten-pound weights are the dependent variable because they can affect the breathing rate.

The breathing rate is the dependent variable because it can be affected by varying weights.

good thing- during decomposition the organic molecules in organic matter are broken down into simpler organic molecules that require further decomposition or into mineralised nutrients

bad thing- it can be harmful in crop productivity

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.
