It gets its nourishment from its mother. The human embryo is connected to its mother by a placenta through which materials are passed.
The mechanoreceptor that is located deeper in the skin and responds continuously to stimulation and is associated with perceiving stretching of the skin is called Ruffini corpuscle.
Mechanoreceptor is a sensory receptor that responds to mechanical pressure. They are connected with sensory neurons that convert this mechanical pressure into electrical signal. It is of four types-
1. Merkel corpuscles- detect pressure and roughness on skin.
2. Ruffini corpuscles- detect deep tension in skin, skin stretch.
3. Meissner corpuscles- perception of light touch and slip on skin.
4. Pacinian corpuscles or Vater-panician corpuscles- detect rapid vibrations.
When these receptors sense a stimuli they gets excited and generates an impulse that travels through the nerve cells into the brain.

Answer:
3.Sedimentary rocks are the only rocks that are weathered. Igneous rocks can change to sedimentary rocks.metamorphic rocks by heat and pressure. All rocks can be melted and cooled to form igneous rocks.
Explanation:
Sedimentary rocks as the name implies are made up of rock sediments which are formed by weathering processes.
Igneous rocks are the rocks which gives rise to sedimentary rocks and metamorphic rocks under certain conditions such as heat and pressure.
All the type of rocks can also be melted and cooled to form back to igneous rocks.
