Which type of rock does b represent? igneous rock metamorphic rock rock formed by compaction rock formed by heat and pressure

Igneous rock

Explanation:

The igneous rocks are formed by magma, a creamy larva that consists between the friction of the plates, after cooling. The very high temperature of the magma, 1100 ° C, and the environment, the interior of the Earth, do not allow the existence of fossils. They are extremely resistant rocks and result in stones such as granite and basalt. One way to remember their formation and why they are called that way is to associate them with their nickname, magmatic rocks.

As we can see rock B in the image shown above, it came out of an erupting volcano, so we can say that it is an igneous rock.

Igneous or magmatic rocks can take longer or shorter to cool, depending on your particular conditions. The magma expelled by volcanoes, for example, forms rocks in direct contact with the surface; therefore, they will form more quickly. These rocks are called extrusives. Rocks whose magma comes from the depths of the Earth's subsoil result in slower cooling and are called intrusive. These are rocks that originate when the magma reaches the Earth's surface and causes cracks in the crust.

advantage of using stem cells in medical research:

1.       it provides medical benefits in the fields of therapeutic cloning and regenerative medicine.

2. it provides great potential for discovering treatments and cures to a variety of diseases including parkinson disease, spinal cord injuries, diabetes, alzheimer’s disease and many more.

3. limbs and organ could be grown in lab from stem cells and then used in transplant or treat illness.
