True or False: Life does NOT need to have all 8 characteristics of life

False

100

The Smallest Unit of Life

Cell

100

TO PROVIDE A CONSTANT SUPPLY OF OXYGEN, WHILE AT THE SAME TIME ELIMINATING CARBON DIOXIDE FROM THE BODY

Respiratory System

100

Blood vessels that carry blood towards the heart. Is this blood Oxygenated or Deoxygenated?

Veins and are deoxygenated

100

Being balanced, stable, equilibrium internally despite changes in the external environment 

Homeostasis 

200

Is the idea that an organism is made up of MANY cells

Multicellular

200

Groups of tissues that work together to perform a closely related function

Organ

200

Air sacs in the lungs

Alveoli

200

Carries oxygen, nutrients, and hormones to cells, and removes waste products, like carbon dioxide.

Circulatory system

200

What are the two types of feedback loops to regulate Homeostasis? 

Negative and Positive feedback loops 

300

Is the idea that organisms are made up of ONE cell

Unicellular

300

Name the 5 levels of organization from smallest to greatest 

Cell, Tissue, Organ, Organ system, and Organism 

300

Name the two structures involved in exchange of oxygen and carbon dioxide in lungs

Alveoli and Capillaries

300

Blood vessels that carry blood away from the heart. Is this blood Oxygenated or Deoxygenated?

Arteries and are Oxygenated

300

Identify 2 ways the Circulatory system maintains homeostasis in our body

1.) Blood vessels such as arteries, veins, and capillaries can dilate and constrict to help the body maintain homeostasis. 

2.) Blood are the transport of nutrients and wastes, defending the body against invaders, and distributing heat to regulate body temperature

400

What is the universal genetic code also known as? 

DNA

400

Identify 2 : Groups of organs that work together to perform closely related functions

Circulatory system, Respiratory system, Digestive system, Skeletal system, Nervous system, etc...

400

The part labeled 4

Lung

400

What are the three main things that make up the Circulatory System?

Heart, Blood vessels, Blood

400

Identify 2 ways the respiratory system maintain homeostasis in our body 

1.) Gas exchange that occurs in the alveoli in the lungs. 

2.) Body dissipates excess heat to maintain homeostasis is through exhalation  (Temperature regulation) 

3.)  Lungs secrete antibodies (immunity)

500

Name all 8 characteristics of life we spoke about

Living things: Are made up of cells, grow and develop, reproduce, based on a universal code, obtain and use materials and energy, respond to their environment, maintain a stable internal environment, and change over time

500

List these from smallest to greatest: Muscle, Muscle Cell, Muscular system, Human, Muscle tissue

Muscle cell, Muscle tissue, Muscle, Muscular system, Human

Alveoli

500

If the heart would stop beating and pumping blood. What would occur? 

Blood would stop circulating through the body. 

500

If blood is not pumped, how would that affect the function of the respiratory system? 

The blood carrying oxygen would not be able to reach our tissues in our body that are essential to living. In addition, an excess build-up of Carbon Dioxide (CO2) would stay in our body, changing the pH of our blood.
