Negative feedback in homeostasis

Opposes or negates a change such as a drop in temperature in the body by creating a response like production of heat opposite direction of inital distubance

Positive feedback in homeostasis

Instead of opposing a change in the internal environment and causing a return to normal, positive feedback tends to amplify or rein-force the change that is occurring

What is intercellular control?

Intracellular control mechanisms operate at the cell level. These mechanisms regulate functions within the cell, often by means of genes and enzymes.

what is intrinsic control?

Intrinsic mechanisms operate at the tissue and organ levels. Sometimes also called local control or autoregulation, intrinsic mechanisms often make use of chemical signals

The term metabolism is used to describe all the chemical reactions that occur in body cells may be called body chemistry

term used to describe chemical reactions that join simple molecules together to form more complex biomolecules—notably, carbohydrates, lipids, proteins, and nucleic acids

an acid is described as?

any substance that will release a hydrogen ion (H+) when in solution

Bases are described as?

are electrolytes that, when dissociated in solution, shift the H+/OH- balance in favor of OH-

what does pH stand for and what does it measure?

abbreviation for a phrase meaning “the power of hydrogen” and is used to mean the relative H ion concentration of a solution

what is a carbohydrate?

include the substances commonly called sugars and starches. Carbohydrates provide the primary source of chemical energy needed by every body cel
