Nerve roots in the spine are the key component of intervertebral disks. a. true b. false

The correct answer is - false.

Explanation:

The nerve root is the beginning part of a nerve that leaves CNS and the spinal cord. It is the initial part of the nerve that is present in between the intervertebral disks and runs through spines which acts as a shock absorber and protects these nerves to any type of damage to these nerves.

The nerve root is not the component of the inter-vertebral disks but initial part of the nerves which are protected by these shock absorbers.

Thus, the correct answer is - false.

cellular respiration oxidizes food into energy in the form of atps.

glycolysis (6 c hexose) > 2x atps are used > 6c hexose biphosphate > 2 x 3c triphosphate >

2 x 3c pyruvate (2x nadh produced from nad) and (4x atp produced)

pyruvate actively pumped mitochondrial matrix.

answer and explanation;

volcanic rocks are igneous rocks which form from lava, molten rock which has been thrust out of a volcano onto the surface of a rocky body such as an asteroid, planet, or dwarf planet.  

plutonic rocks are igneous rocks which form from subterranean chambers of molten rock or magma. plutonic rocks make up the base of continental crust as well as oceanic crust. their slow rate of formation causes them to be coarse grained since there is plenty of time for large crystals to form before the magma solidifies into rock.

the textural difference is that plutonic rocks are more coarse grained than volcanic rocks. plutonic rocks are coarse grained while volcanic are fine grained ; glassey or fragmental. since fine and coarse are adjectives the decision as to whether a rock is fine or coarse grained is generally made on the bases of whether or not the individual crystals can be seen in most if the rock.
