Answer:
all are correct i think so
Answer: TRUE
Explanation:
Sound waves enter the OUTER EAR and travel through a narrow way up to the eardrum, where it vibrates.
The vibrations are sent to the bones of the MIDDLE EAR where they are amplified, and passed to a structure called COCHLEA in the INNER EAR.
Finally, it reaches the sensory cells that passes it to the auditory nerve that transmit the sound to the brain as electrical signals (neural messages) for proper interpretation.
So, it is True because from OUTER EAR to MIDDLE EAR, to INNER EAR.
1)Control Group - Group that does not receives the treatment.
2)Experimental Group - Group that receives the treatment.
3)Constant - The variable you keep the same.
4)Independent Variable - The variable you control.
5)Dependent Variable - It depends on the independent variable.
Example:
You want to know how much taller plants will grow with fertilizer. You do an experiment. Flower A receives fertilizer but flower B does not. Both flowers receive the same amount of water and sunlight. The control group would be flower B, the constants would sunlight and water, the independent variable would be the fertilizer., the dependent variable would be the plant's height, and the experimental group would be flower A.
B. skeletal and nervous system
The stem and plants store water in the vacuole
