Answer:
B. Oxidation of food through the process of cellular respiration
Explanation: During cellular respiration oxygen molecules combines with glucose and forms ATP or adenosine triphosphate an energy giving molecule to sustain cellular activities.

Answer:
A dorsal root (sensory or afferent) and a ventral root (motor or efferent) originate from the medulla. They unite near the intervertebral foramen, forming the spinal nerve. The nerves emerge from the intervertebral foramen, dividing into ventral and dorsal ramus.
Explanation:
The nerve is a set of nerve fibers perceptible to the naked eye and wrapped in connective tissue. They are made up of roots, trunks and nerve branches (some of them come together and form plexuses).The spinal nerve originate from the spinal cord in the form of 31 pairs: 8 cervical, 12 thoracic, 5 lumbar, 5 sacral and 1 coccygeal. They emerge from the spinal cord through two roots: dorsal roots, made up of sensory fibers that come from the sensory neurons of the spinal ganglion and that penetrate the spinal cord through the posterolateral and ventral root, made up of motor fibers, coming from the motor neurons of the anterior horn and visceral of the lateral horn of the gray matter of the spinal cord. This root exits the spinal cord through the anterolateral groove, then joins the posterior root to form the spinal nerve, which exits the vertebral canal through the corresponding intervertebral foramen.Each spinal nerve, after leaving the vertebral canal, emits two primary ramus: the dorsal ramus, contains somatic and visceral fibers that go to the skin and muscles of the back and the ventral ramus, which supplies the ventrolateral surface of the skin, body wall and extremities.
A cell is the basic unit of life.
DNA is the giant molecule consisting of the sugar deoxyribose, phosphates, and nitrogen bases.
Homeostasis is the maintenance of a constant internal body environment by an organism's body.
Metabolism is all of the chemical reactions in the organism for maintenance of the processes of life.
An organelle is a small structure within the cell that serves specialized functions.
<h3><u>Explanation:</u></h3>
Cell is defined as the structural and functional unit of the living body. An organism may be either unicellular or multicellular, but cells are the basic structure of the living object.
DNA is the genetic molecule that is formed of sugar phosphate backbone, nitrogen bases and ribose sugar. It's essential for storing genetic information and passing them to next generations.
Homeostasis is defined as the maintenance of internal conditions of temperatures and other parameters irrespective of external conditions.
Metabolism is defined as the collection of chemical reactions going inside an organism to produce energy and other compounds which is required for the normal healthy life.
Cell organelles are defined as the small structures that are present inside a cell responsible for performing specialized functions which collectively forms the functions of a cell.
Answer:
Isocitrate dehydrogenase and α‑ketoglutarate dehydrogenase are the two enzymes that produces carbon dioxide as a by-product.
Explanation:
The release of carbon dioxide from any compound is known as decarboxylation. The first step where carbon dioxide is released as a by product is when Isocitrate is oxidized and decarboxylated to α‑ketoglutarate and this reaction is catlyzed by isocitrate dehydrogenase. The second step where carbon dioxide is released as a by product is from decarboxylation of α‑ketoglutarate into succinyl-Co A and this reaction is catalyzed by α‑ketoglutarate dehydrogenase.
