Explanation:
The universal wave equation states that the velocity of a wave is the product of its wavelength and its frequency.

I think that the hands should be placed on top of the muscle that needs to be contracted.
One of the exteroceptive stimulation techniques is MANUAL CONTACTS.
Under this technique, the hands will exert firm and deep pressure on the contact of the body where the muscle is located. This activates the <span>tactile or touch receptors and muscle proprioceptors. This also facilitates muscle contractions; muscles that are directly under the hands and provides support and security to unstable body parts or segments.

Answer:
Parents genotypes are: Pp (purple) and pp (white).
Top left box: Pp
Top right box: pp
Bottom left box: Pp
Bottom right box: pp
So because of this you have 50% purple and 50% White
Hope this helps :D
(The second one is similar but with both parents being Pp so it’s 100% purple 0% white)
Answer:
true
