Answer:
A. They are constantly moving. I think.
Explanation:
Each lithospheric plate is composed of a layer of oceanic crust or continental crust superficial to an outer layer of the mantle. Containing both crust and the upper region of the mantle, lithospheric plates are generally considered to be approximately 60 mi (100 km) thick. Earth's tectonic plates may have taken as long as 1 billion years to form, researchers report today in Nature. The plates — interlocking slabs of crust that float on Earth's viscous upper mantle — were created by a process similar to the subduction seen today when one plate dives below another, the report says. A tectonic plate (also called lithospheric plate) is a massive, irregularly shaped slab of solid rock, generally composed of both continental and oceanic lithosphere. Plate size can vary greatly, from a few hundred to thousands of kilometers across; the Pacific and Antarctic Plates are among the largest.
Answer:
Peristalsis is a series of wave-like muscle contractions that move food through the digestive tract. ... There, the food is churned into a liquid mixture called chyme that moves into the small intestine where peristalsis continues. Stretching out a piece of intestine will make it easier to see the wave-like motion
Answer:
Inheritance Patterns
Explanation:
Mendel was studying how genes are past on to future generations and in what circumstances this can occur. He used pea plants as they multiply and grow quickly allowing him to observe many generations much faster than he would be able to observing humans or even other mammals. He also used pea plants because this way he could control reproduction of his pea plant population to adjust to specific questions he had in terms of his research.
I believe its the sensory neuron and the the sense organ to the brain as the sense nerves in his hand would feel the pain and send that information to the brain so it can react
