Cells are the basic building blocks of life. Describe the relationship between cells, tissues, organs, organ systems, and organisms.
What is many cells make up a tissue; many tissues make up an organ; many organs make up an organ system; many organ systems make up an organism.

The skeletal system gives the human body shape (framework) and also supports the body. Give at least one other function of the skeletal system.
What is to protect internal organs, store and produce red and white blood cells, etc.
100
What are the three types of blood vessels?
What are arteries, veins, and capillaries

The ___________ and the __________ ________ make up the _______________ nervous system, while the rest of the body makes up the __________________ nervous system.
What is brain, spinal cord, ?central, peripheral

Name two inherited traits and one behavior that is not inherited.
What is Inherited traits may be evaluated with these critera: detached earlobes, tongue rolling, dimples, right-handed, freckles, curly hair, cleft chin, allergies, cross left thumb over right, can see green and red colors, have a straight hairline. Learned behaviors may be: how to bathe, cook, do homework, be responsible, be kind, how to use a computer, how to play Words-with-Friends, your food preferences, your favorite color

Plants and animals have different kinds of cells. Which of the following is true? A) Plant cells have a cell wall, choloroplast, and a small vacuole. B) Animal cells have a large vacuole and a cell wall. C) Plant cells have a large vacuole, cell membrane, chloroplast, and a cell wall. D) Animal cells have a large vacuole, cell membrane, and a chloroplast.
What is C. Plant cells have a large vacuole, cell wall, and a chloroplast for chlorophyll and photosynthesis. Animal cells have a tiny vacuole, cell membrane, and NO cell wall and NO chloroplast. Both plant and animal cells have a similar, medium-sized nucleus near the middle of the cell, and cell membrane.

How do the skeletal and muscular systems work together?
What is skeletal muscles are attached to bones by tendons. They work together to help the body move. Also, the bones protect the cardiac muscle (heart) and allow space for smooth muscles to stretch.

____________ carry red, oxygenated blood away from the heart. _____________ carry blue blood without oxygen back to the heart.
What are Arteries (away) Veins (return)

Classify these organs as part of the nervous system, digestive system, or other: small intestine, cerebrum, lungs, mouth, bronchi, ribs, spinal cord, liver, cerebellum, esophagus, frontal lobe, bicep, neurons, stomach, heart, skull, arteries, skin.
What is Nervous System – cerebrum, spinal cord, cerebellum, frontal lobe, neurons Digestive System – small intestine, mouth, liver, esophagus, stomach Other – lungs, bronchi, ribs, bicep, heart, skull, arteries

Explain one possible reason why a child may have dimples but the child’s mother and father do not have dimples.
What is Dimples may have been inherited from the grandparents.
300
Which of these is a simple, single-celled organism: A) Dog B) Bird C) Amoeba D) Worm
What is amoeba.

What’s the strongest muscle in the human body?
What is the heart
300
Both the cardiovascular and respiratory systems work with oxygen and carbon dioxide, where most gas exchange occurs in humans. How do their jobs contrast (differ)?
What is Using the lungs, the respiratory system exchanges gases by bringing oxygen into the body and taking carbon dioxide out. Using the heart, the cardiovascular/circulatory system exchanges gases by pumping and circulating oxygen from the lungs throughout the body and taking carbon dioxide from the body back out through the lungs.

Nerve cells = neurons. Impulse = electrical current carrying information. Synapse = gap between each neuron. Neurons may be thought of as several small, disconnected wires that conduct electricity. In order for an impulse to be transferred from one neuron, across the synapse, to another neuron, in the electrical circuit between the central and peripheral nervous systems, the neurons must be _ _ _ _ _ _ _ _. This must be happen for conduction to occur.
What is touching.
300
True or False: A daughter should have exactly the same traits, DNA, and looks her mother. Explain why or why not.
What is False. Some traits may be inherited from the mother and some from the father. Children have similar DNA as their parents, but not congruent.
400
Unicellular organisms are simple. Multicellular organisms are complex. Which of the following is false? A) Unicellular organisms use tiny hairs (flagella) for locomotion (movement). B) Bacteria, amoeba, paramecium, and euglena are all unicellular. C) Multicellular organisms have no way to transport (move) wastes, nutrients, water, or blood throughout the body. D) Unicellular organisms do not have transport systems.
What is: C

There are >3 times as many muscles as bones in the human body. About how many muscles and bones are there?
What is Adult Human Body: 206 bones Adult Human Body: ~650 muscles
400
During a fifth grader’s 60 minutes of exercise each day, the heart beats faster than a resting heartbeat. Why?
What is during exercise, muscles need more oxygen, because they are working hard! Respiration increases. The heart must pump blood faster to circulate oxygenated blood to the muscles and to take carbon dioxide out.
400
Which of the following is neither the role of the digestive system nor the nervous system? A) Take nutrients from food for the body to use as energy B) Solve problems, process stimuli from the senses, memory C) Release nutrients from the small intestine into the bloodstream D) Fight infection with WBCs, circulate RBCs through plasma
What is D (cardiovascular/circulatory system)

Classify each behavior as instinctive (you were born with the behavior), or learned (you learned the behavior after birth): sleeping, brushing your hair, eating, jumping rope, chewing, blinking, building an eco-column or K’NEX car, swallowing, researching data on Weatherbug, crying, texting, and doing the chicken dance.

Which is true of both unicellular and multicellular organisms? A) They both have highly specialized cells. B) They both have transport systems. C) They both have a way to take in nutrients for growth. D) They both have several different kinds of organs.
What is: C

Muscles work in pairs. When one muscle ________________, an opposite muscle ________________.
What is contracts, expands

Name the four main chambers of the heart and at least two main parts of the respiratory system.
What is Heart chambers: right atrium, right ventricle, left atrium, left ventricle. Respiratory parts: lungs, bronchi, bronchiole, alveoli, nose, mouth, pharynx, larynx, trachea, etc.

Adults usually confuse the esophagus with the stomach. What’s the difference between the two?
What is Esophagus – muscles squeeze food from the throat to the stomach (peristalsis process) Stomach – chemicals (enzymes) mix with food to make liquid mush, called chyme. Chyme moves mush to the small intestine in about four hours.

Which of these behaviors is an acquired trait (not inherited) for an animal? A) bird flying B) chameleon camouflaging itself C) dolphin jumping through hoops at circus D) dog wagging its tail
What is C) dolphin jumping through hoops at circus. Davey the Dolphin probably learned this from a trainer or from Mr. Mack.
