How does the muscular system work with the skeletal system?
The muscles in the muscular system moves the bones of the skeleton.
Which body system is responsible for movement?
The muscular system.
What is the smallest living part of an organism?
A cell.
What role does DNA play for a cell?
It contains the instructions/blueprints for the cell's function(s).
What do all of these traits have in common?
Hair color, height, eye color, facial structure, ear lobes.
They are all inherited traits that come from DNA.
How does the circulatory system work with the respiratory system?
The circulatory system brings CO2 to the lungs for removal and takes O2 from the lungs to the rest of the body.
Which body system is responsible for extracting nutrients from food?
The digestive system.
Why is a unicellular organism able to survive on its own?
Because it can perform all of the functions of life in one cell.
Do unicellular organisms have DNA? Why or why not?
Yes! They need instructions for how to live, just like multicellular organisms.
Which is these is most influenced by a person's environment (a learned/acquired trait)? Choose ALL correct answers.
Sports skills
Skin color
Language
Intelligence
Cheek dimples
Sports skills, language, and intelligence.
How does the skeletal system work with the circulator system?
Marrow inside the bones produces new red blood cells for the circulatory system.
Which system has the following structures: Trachea, Bronchioles, and Alveoli.
The Respiratory System.
In a multicellular organism, specialized cells group together to form tissues. These tissues form _________. And these ________ form _________________. (Fill in the blanks. Half credit for getting one of the answers.)
Organs...and Body Systems/Organ Systems/Transport Systems.
What does DNA stand for? Correct spelling is required.
Correct spelling: deoxyribonucleic acid.
What do unicellular and multicellular organisms both need to do?
Perform the functions of life.
Which systems directly interact with the outside environment?
Neurons form the main cell structure of which body system?
The nervous system.
What does it mean to have specialized cells?
Each cell has a job. Cells that have the same job are grouped together into systems.
If a mother has a scar on her skin, would her child be born with that scar as well? Why or why not?
The child will not have the scar. DNA passes on inherited traits, not acquired traits.
What's the best explanation for why a child has the same eye color as her parents?
They share some DNA (genetic structures).
Which body systems are considered transport systems?
The Digestive, Nervous, Circulatory, Respiratory, and Muscular systems.
Which body system use involuntary muscles? (Half credit for the specific organ involved; full credit for the organ and the system.)
Possible answers vary.
Why does a multicellular organism like a human need body systems?
The systems transport things into and out of the body, because it has so many cells that not all of them can interact with the outside world.
What would need to happen for a child to be born with a disease that the parent had?
The disease would need to have instructions in the DNA the parents.
Why is it an advantage that humans have to learn some traits (instead of just inheriting all of them)?
Answers vary.
