All the nerve bundles of the mammalian body system are routed through the spinal cord.
The correct answer choice is option C.
The importance of the nerve bundles to the spinal cord.The nerve bundles are those structures within runs from the nervous system throughout all the body parts. They are electrical wires which helps to transmit signals or electrical impulses.
That being said, the spinal cord signals different electrical impulses from the brain to different parts of the body and also from different parts of the body back to the brain.

The nephron, a functional unit of the kidney, is made up of structures called renal tubules. Nephron functions include controlling the balance of water and body electrolytes, reabsorption of glomerular filtrate, and secretion of waste products. The majority of reabsorption takes place in the proximal contoured tubule of the renal tubules. Electrolyte equilibrium is affected by Henle's handling. Distal contoured tubule in charge of secreting chemicals for elimination.99% of the glomerular filtrate can be reabsorbed by the renal tubules. Since the tube flow is dependent on the rate of glomerular filtrate, which is roughly 120 millilitres per minute, an increase in glomerular filtrate will result in an increase in both the amount of filtered fluid flowing and the amount that flows.

Antibodies are protein molecules that the body produces in reaction to the introduction of foreign substances (also known as antigens or immunogens).
When an organism's immune system comes into contact with a foreign molecule for the first time (usually a protein), specialized cells like dendritic cells and macrophages seize the molecule and start to break it down so that they can transmit these antigens to B cell lymphocytes. A process known as somatic hypermutation enables the B cell to start coding for a new antibody after antigen presentation to the B cell lymphocytes has taken place. This antibody will have a distinctive Antigen Binding Site in the variable region that can bind specifically to an epitope from the antigen.

What type of hormones use second messengers in a cascade of reactions that trigger a cell response?.
G-protein use second messengers in a cascade of reactions that trigger a cell response
Understanding G-protein
G protein plays a role in managing the initial (extracellular) signal received by the receptor and then forwarding it into the cell (intracellular) which triggers the activation of cellular responses, namely effector proteins that play a role in various cell responses such as development, growth, hormone regulation, et al. The scalar here refers to the role of the on/off G protein in managing signal transduction.
This protein is a push button located next to a specific protein receptor on the cell, this protein can trigger the activation of a protein (effector protein) such as an enzyme. The G protein is able to bind to the guanosine-5′-triphosphate (GTP) molecule, the message it carries is a specific signal transduction. The first activation is able to produce effector proteins that will later form the second messenger (second message), the second message can forward the first message to carry out an intracellular response, for example a common effector protein such as adenylyl cylase can produce cAMP as a second message. Other second messages include inositol phosphate and calcium ions.

Chromosomes are visible under a microscope during mitosis, more specifically when they're being copied.
During interphase, chromosomes are not really visible under a microscope. It's because they only exist in the form of loosely condensed chromatin fibers in this phase, making them hard to see.
Chromosomes only began to become visible during prophase, when centrioles start to move to the opposite poles of the cell. In this phase, chromatin is condensed, which makes individual chromosomes become visible.
