Through hormone signaling, the endocrine system is in charge of managing homeostasis.
Backwards is where the spinal column is situated (at the back). Anteriorly are the clavicle, sternum, and mandible (front).
Epithelial tissue serves as the lining and covering of the body's cavities and surfaces.
"Two distinct cell division processes are meiosis and mitosis.
A single cell divides into two identical daughter cells during the process of mitosis. Mitosis is mostly used to replace harmed and worn-out cells."
Since ribosomes are the organelles in charge of protein synthesis, it makes sense that they would predominate in cells that secrete protein, like osteoblasts.
By fusing its genetic material with that of the host cell, HIV infects the host cell. The nucleus is where the genetic material is located.
The fundamental cells that make up the nervous system are called neurons. The mitochondria will be the simplest structure on the list because it is an organelle that can be found inside a neuron. The brain is made up of nervous tissue, which is composed of many neurons.
Because they must get rid of dangerous invaders like bacteria and viruses, white blood cells have more lysosomes than other blood types. Waste from a cell is broken down and eliminated by lysosomes. This indicates that they can destroy germs and viruses that the body attempts to defend itself against by engulfing them in white blood cells.
Anabolic reactions employ energy to create the compounds that the organism needs. In a "catabolic process," complex molecules are broken down into simpler ones to provide energy the organism can use.
An element loses one or more electrons to oxygen during oxidation.
An element gains one or more electrons during reduction.
The process by which a cell takes in oxygen and uses it to break down glucose to produce energy in the form of ATP is known as cellular respiration. The electron transport chain, the last phase of cellular respiration, is where oxygen absorbs electrons and picks up protons to create water. Therefore, cellular respiration is both a "oxidative" and "catabolic" activity because oxygen causes elements to lose electrons and because it is a reaction in which energy is produced.
