Answer:
A chemical reaction is the process in which atoms present in the starting substances rearrange to give new chemical combinations present in the substances formed by the reaction. These starting substances of a chemical reaction are called the reactants, and the new substances that result are called the products.
Explanation:
Answer: Bundles of axons in the central nervous system are called a "tract"
Explanation:
Axons(nerve fiber) consist of long slender projection of neurons or nerve cells that conduct and transmit impulses away from the neuron or nerve cell body. Axons are surrounded by endoneurium layer which contain protein fluid that surround each axon.
Bundles of axon in the CNS is known as tract. We have ascending tracts and descending tracts. The ascending tracts function are to conduct and carry impulses along the spinal cord to the brain while the descending tracts transmit and carry the impulses from the brain to lower regions (downward) of the body. Tracts are identified by their origin (where the bundle start) and also the end/termination of axon bundle.
The largest tracts are fasciculi gracilis and cuneatus which are known as ascending tracts.
Absolutely! The Calvin Cycle is a process that takes place within the stroma of chloroplasts during photosynthesis. This cycle is a light-independent reaction because it does not need sunlight to fully develop. The process is, however, dependent on ATP and NADHP from those light reactions.
