A. Enzymatic. The three major types are humoral, hormonal, and neural stimuli
option-A if there is a change in the oxidation states of atoms from reactants to products, the reaction in an oxidation reduction reaction describes the oxidation-reduction .
We know that oxidation is a process that increases the oxidation number, whereas reduction is a process that decreases the oxidation number. An oxidation-reduction (redox) is a type of chemical reaction wherein the electrons are exchanged among distinct strains Any chain reaction that occurs when the oxidation number of the a molecule, atom, or ion modifications by acquiring or losing an electron is an oxidation-reduction reaction. Reduction-oxidation reaction any chemical reaction in which one species oxidizes (loses electrons) while another species reduces (gains electrons) Oxidized. defines an element that has lost electrons and increased its oxidation number

the complete question is:
Which best describes oxidation-reduction reactions?
A- if there is a change in the oxidation states of atoms from reactants to products, the reaction in an oxidation reduction reaction
B-If there is formation of salt and water, the reaction is an oxidation-reduction reaction.
C-If there is formation of a precipitate, the reaction is an oxidation-reduction reaction.
D-If there is no change in the oxidation states of atoms from reactants to products, the reaction is an oxidation-reduction reaction.
A blood cell would travel along the femoral, popliteal, anterior tibial, and dorsalis pedis arteries as it traveled from the thigh to the foot.
<h3>What is the sequence in which the arteries carry blood?</h3>
The red blood vessels, or arteries, transport oxygen and nutrients from your heart to your body's tissues. The veins (blue) return the heart's oxygen-deficient blood. The aorta, the main artery leaving the heart, is where arteries are born. They deliver blood that is rich in oxygen out from the heart to all the body's tissues.
<h3>What is the artery's direction?</h3>
Blood is carried by veins toward the heart and by arteries away from the heart. Veins transport deoxygenated blood, and arteries carry both, with the exception of pulmonary blood vessels. Muscle tissue lines the thick walls of arteries. Veins use valves and have thinner walls to keep your blood flowing.

Answer:
D. Theory
Explanation:
With repeated testing, some hypotheses may eventually become a scientific theory. A scientific theory is a broad explanation for events that is widely accepted as true. To become a theory, a hypothesis must be tested over and over again, and it must be supported by a great deal of evidence.
