Jordan is doing a science fair project on the effects of music on the growth of tomatoes. he has two tomato plants, plant a and plant b, that he grows in a window and gives the same amount of water. plant a is exposed to classical music using headphones attached to the soil. throughout the growth period, jordan counts the number of tomatoes produced by each plant. list one of the experimental constants in this experiment.

Water and sunlight are the experimental constants.

Explanation:

As we know, scientific experiments are composed of variables (dependent and independent) that are factors that researchers can manipulate to provoke a reaction that allows them to observe results. What few know is that in addition to variables, experiments are composed of factors called "constants". Experimental constants are factors that are maintained in the same way throughout the experiment without being manipulated. An example of this can be seen in the question above, where the researcher used as constant the amount of water supplied to plants and the amount of sunlight.

a motor homunculus represents a map of brain areas dedicated to motor processing for different anatomical divisions of the body.

homunculus represents the importance of various parts of your body as seen by your brain. as a result, they take up a lot of brain space. although the cortical homunculus is a curiosity, penfield's work in mapping the brain's relationship to the body was invaluable.
