The answer is stem cells, they consist of classes of cells
that are undifferentiated and are able to be classified them into types like
specialized cells. They consist of having two main sources that will help them
develop and mature, these main sources are called the embryonic stem cell and
the adult stem cell.

Answer:
See the answer below
Explanation:
Homeostasis refers to the maintenance of relatively constant internal body processes. This is done in two ways
- <em>Negative feedbacks</em>
- <em>Positive feedbacks</em>
Negative feedback returns body processes back to normal after the process has been breached. An example is when the body temperature becomes too high or too low. At too high temperature, vasodilation of the skin's blood vessels occurs and more heat is lost to the surrounding from the skin, sweat is also produced by sweat glands and evaporation of the seat causes cooling. At too low temperature, vasoconstriction occurs leading to the conservation of more heat. The muscles also shake to generate more body heat
Positive feedback ensures that a breach of body processes reaches completion. An example is when a pregnant woman starts laboring. The increase in the amount of oxytocin in the blood leads to the contraction of the uterus consequently leading to the opening of the cervix. More and more oxytocin leads to more frequent and stronger contraction of the uterus untill the baby is born.

Cheating on questions is irresponsible behavior
Explanation:
Histotoxic hypoxia, which happens whenever body cells are not able to utilize oxygen while receiving sufficient amounts, is typically caused by metabolic toxins like cyanide.
What is hypoxia?
- Hypoxia is a state in which there is insufficient oxygen reaching the tissues throughout the system or a specific area of the body.
- Although fluctuations in arterial concentrations of oxygen are frequently associated with clinical conditions, they can also occur naturally during severe physical activity or hypoventilation training.
When does Histotoxic hypoxia occur?
When the supply of gas entering the cell is adequate, but the cells are unable to utilize the oxygen properly due to deactivated oxidative phosphorylation enzymes, histotoxic hypoxia develops. Ingestion of cyanide may result in this.
