Answer:
I believe the answer is A
Explanation:
I think it is A because the original function of the spinal cord is to complex organization of nerve cells responsible for movement and sensation. It carries signals between the brain and the rest of the body.
Answer: A neuron has three main parts: dendrites, an axon, and a cell body or soma , which can be represented as the branches, roots and trunk of a tree, respectively. A dendrite (tree branch) is where a neuron receives input from other cells. Dendrites branch as they move towards their tips, just like tree branches do, and they even have leaf-like structures on them called spines.
The axon (tree roots) is the output structure of the neuron; when a neuron wants to talk to another neuron, it sends an electrical message called an action potential throughout the entire axon.
The features of neurons help them to carry out their function efficiently:
they have a long fibre (axon) so they can carry messages up and down the body over long distances
in a stimulated neuron, an electrical nerve impulse passes along the axon
the axon is insulated by a fatty (myelin) sheath - the fatty sheath increases the speed of the nerve impulses along the neuron
at each end of the neuron are tiny branches (dendrons), which branch even further into dendrites - the dendrites receive incoming nerve impulses from other neurons

Differences and similarities between igneous , metamorphic , and sedimentary rocks . sedimentary rocks are formed by weathered sediment using cementation or precipitation on Earth's surface . Metamorphic rocks are formed by changes of pressure and temperature within Earth's surface .
Answer:
Letter D, Herpes simplex
Explanation:
Herpes simplex is caused by the herpes virus (HSV). The herpes virus can infect different parts of the body depending on the type of virus.
HSV-1: cusses blisters around the mouth, including eyes in the case of several infections.
HSV-2: responsible for genital infections.
The signs and symptoms include blistering in the infecting area, itching and flu-like symptoms (fever, headache, etc.)
Answer: Inclusions or inclusion structures serve as temporary storage of molecules like glycogen and melanin.
Inclusion structures are the aggregates formed of specific molecule types.
The inclusion bodies serve the purpose of temporary storage for molecules such as proteins, lipids, glycogen and melanin. One of the major differences between cell organelle and cell inclusion is that organelles are the living components or subcomponents which have particular functions but cell inclusions are non-living compounds or by products of metabolism process present in the cytoplasm.
