Experiment: What is the effect of drinking coffee on a person's score on a memory test? Which of the following would be the INDEPENDENT VARIABLE?
O Coffee
O Decaf coffee
O Memory test score
O Type of cup used

The independent variable would be the coffee.

Explanation:

In an experiment, the independent variable is something that is added or changed by the scientist in order to see if there will be a response.

In this case, the memory test score would be the dependent variable (something that changes as a result of a change in the independent variable).

Decaf coffee could be a control group, or a group that is treated the same as the independent variable but without being exposed in order to account for any outside factors.

Finally, the type of cup used would be a constant between the control group (using the decaf coffee) and the experimental group (the group with regular coffee).

Hope this helps!

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.

then go eat. lol.brainliest
