An organism must be made up of a membrane-covered structure that contains all the materials necessary for life. Many organisms are made of million or trillions of these small units.

Metabolism is the total of all the chemical activities that an organism performs and it falls under which characteristic?

In order to continue the species all organisms must either unite two cells to form a zygote or produce an offspring from itself.

All organisms must remain in Homeostasis

All organisms store complex information in a molecule called DNA

A single fertilized egg divides and divides increasing the volume of the organism then eventually begins to differentiate or look different and perform different functions.

Organisms detect and respond to stimuli.

Organisms change over time and that change links all forms of life to a common origin 3.5 billion years ago.

process of reproduction involving a single parent that results in offspring that are genetically identical to the parent

type of reproduction in which cells from two parents unite to form the first cell of a new organism

signal to which an organism responds

the combination of chemical reactions through which an organism builds up or breaks down materials

relatively constant internal physical and chemical conditions that organisms maintain

Scientific study of life

True or False? Negative feedback increases the likelihood of the event to continue.

In the process of blood clotting, an enzyme is produced that forms the matrix of the blood clot, but also speeds up the production of that same enzyme. This is ______ feedback.

Organ systems maintain which of the following at just the right levels to support life processes?

According to the scientific definition of life, which of the following groups contain ALL living things?

True or False? A single celled bacteria can have liver damage which prevents the organism from maintaining homeostasis.

True or false?  Organ systems are made of multiple organs that work together to maintain homeostasis in an organism.

True or False? The endocrine system is made up of hormone-secreting glands.

True or False? Viruses are alive.

The smallest level of organization that can be considered alive is the:

Can a unicellular organism get diabetes?

In addition to body temperature, control of ________ levels is also maintained by negative feedback

Which example represents positive feedback?

In temperature regulation, when the blood temperature drops, signals are sent to contract the arteries near the skin and to begin shivering. This keeps blood in the core and releases heat energy. This is ______ feedback.

During childbirth, the stretching of the uterus triggers the secretions of a contraction-stimulating hormone to speed up labor. This is an example of ____________________ feedback.

What is the largest, most complex level of organization that UNICELLULAR organisms have?

True or False? Multicellular organisms have specialized cells that are grouped together to carry out specialized functions.

A group of connected cells that have a similar function within an organism is called a (an) _____.

Humans have ____ for body temperature, blood glucose concentrations, electrolyte concentrations and pH levels.

Homeostasis in the human body is often maintained by a 

Which two body systems work together to regulate blood glucose levels?

The air conditioner in the science classroom turned on when it became too warm. This is likened to what negative feedback system in a living organism?

 After a person eats a large meal, glucose begins to move into the bloodstream and the level of insulin released by the pancreas 

The pancreas of a person with Type I diabetes produces no insulin. People with this condition must get insulin injections to prevent 

Diabetes is best defined as:
