A student put a half teaspoon of yeast in each of three different balloons. Then he added a quarter cup of water to each balloon. Each balloon received water of a different temperature: hot, warm, and cold. After adding the water, the student tied off the end of each balloon to seal it shut. The yeast began to produce bubbles of gas inside the balloons. After 20 minutes, the student measured the circumference of each balloon to determine how much it had grown in size.

What is the responding variable in this experiment?

Did you get the answer right yet I need help on that guestion to

Explanation:

I have the same question!

The choices are

A. The temperature of the water balloon

B. The amount of water placed in the balloon

C. The circumference of the balloon

D. The amount of yeast placed in the balloon

I think its D

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.
