3. Now, using the same word bank of organelles in Q1, organize them in three groups according to their

function: Metabolism, Homeostasis, or Heredity

Metabolism Homeostasis Heredity

4. Here is a list of human diseases and disorders. Each one of them is caused by the failure of one or two

specific organelles inside our cells. Read each description, then state which organelle has failed.

Infertility is sometimes caused by sperm cells’ poor motility; they can’t “swim”

Cystic Fibrosis patients can’t clear mucus from their trachea; it accumulates in lungs

Cystic Fibrosis patients also don’t secrete pancreatic enzymes very reliably.

Down Syndrome occurs when chromosomes divide unevenly during mitosis.

Elliptocytosis is a condition where the red blood cells are a stretched oval shape.

In cardiac disease, heart muscle gets progressively weaker and weaker over time

5. What does the term semipermeability mean?

6. Which of these cells is in a Hypertonic environment? Which is Hypotonic, and which is isotonic? Label them.

Then, below each, briefly state what will happen to each cell if you wait a half hour.

7. Identify which stage of mitosis each cell is in.

UNIT 2: GENETICS

1. Complete the following table, comparing Mitosis and Meiosis:

Mitosis Meiosis

How many stages?

What type of cells are produced?

Are daughter cells haploid or diploid?

Overall role:

What is the result if an error happens?

2. Match up the terms with their meanings. Write the letters next to the numbers in the answer column.

1 HOMOZYGOUS A Message coded in our DNA 1

2 HETEROZYGOUS B A symbolic description of your genes 2

3 GENE C Description of traits in ordinary words 3

4 ALLELE D When two traits blend in a hybrid 4

5 GENOTYPE E Inherits two identical alleles 5

6 INCOMPLETE DOMINANT F When both traits show up in a hybrid 6

7 CODOMINANT G Different versions of our genes 7

8 PHENOTYPE H Inherits two different alleles 8

3. Curly hair is dominant C, straight hair is recessive c. If a couple both

have curly hair, but each of them had a parent with straight hair, what

is the chance they will have a straight-haired child? Show a complete

punnett square, with genotypic and phenotypic ratios.

4. In some breeds of dogs, Black fur B, and brown fur b, are

codominant. The heterozygous genotype Bb, results in coat

pattern called brindle, where both colours are seen. If a brindle

male is mated with a brown female, what is the chance of having a

brindle pup? Show a complete punnett square, with genotypic and

phenotypic ratios.

5. Snapdragon flower colour is an incomplete dominant trait. Red is

dominant, R, and white is recessive, r. Heterozygotes are pink. If

a plant breeder pollinates a pink flowered plant with pollen from

another pink plant (pink x pink), what phenotypes will be found

among the offspring plants? Show a complete punnett square,

with genotypic and phenotypic ratios.

6. Colour blindness is a human trait carried on the X chromosome.

It is a recessive trait, Xc . Full colour vision is dominant, XC. If a

colour blind man, XcY, and a carrier woman, XCXc have children

together, what is the chance that they will have a colour blind

child? Show a complete punnett square, with genotypic and

phenotypic ratios.

7. Cats have many different genes for fur colour. One

gene, the Agouti gene, gives agouti (Tabby) fur

pattern when dominant, A, and black fur when

recessive, a. It is a simple dominant trait. Another

trait is an incomplete dominant. The dominant

trait, S, gives large white spots; the recessive trait,

s, gives very few white spots. Heterozygous cats,

Ss, have a medium amount of spots. If two tabby

cats with a few white spots, both AaSs, are mated,

what will their kittens look like?

UNIT 3: BODY SYSTEMS

1. Use the diagram below to identify and define the Levels of Organization in a vertebrate body.

2. Here are the hearts of different vertebrates. Look carefully at them, and explain how their heart structure is

related to their metabolism and habitat.

3. Blood is our only fluid tissue. Other than cells, what would you find in our blood plasma?

4. Blood clots form as a result of two chemical

reactions. They are shown to the right, with

two proteins missing. Write in the missing

proteins. Why is it a good thing for our

bodies that clots form in this way?

5. The list below states the functions of different blood cells. Check off which ones apply to each cell type.

Role: Red Blood Cells:

Platelets: White blood cells:

Immunity

Formation of clots

Carry oxygen

Allergic responses

Make antibodies

Store Hemoglobin

Destroy bacteria

Have no nucleus

Low in Hemophilia

Low in Anemia

High in Leukemia

6. Examine the diagram to the right. Use one colour of highlighter

to to highlight the path of oxygenated blood, and a different

colour to highlight deoxygenated blood. Then, label the diagram

to show the systemic loop and the pulmonary loop.

7. Identify all of the numbered structures on the human heart, below.

8. Label the diagram of the human respiratory system, below.

9. Use the diagram below to explain how humans breathe. Use the following words to help your explanation:

ACTIVE PROCESS PASSIVE PROCESS DIAPHRAGM RIB CAGE

EXPANDS CONTRACTS PRESSURE RISES PRESSURE FALLS

10. List three facts about the alveoli of our lungs.

11. The diagram of a frog shows its lungs. How do they compare to

human or mammal lungs? How is the lung structure of frogs and

mammals linked to what they can do, and what their metabolism is like?

12. Identify the organs of the digestive system. For each organ, state one general function.

13. Match up the terms related to digestion with their correct definitions:

1 PERISTALSIS A Tiny intestinal projections, increase absorption 1

2 ENZYME B Wave of muscle contractions, helps us move food 2

3 EPIGLOTTIS C Chewing, swallowing, stomach contractions 3

4 MECHANICAL DIGESTION D HCO3, neutralizes stomach acid in the sm. intestine 4

5 CHEMICAL DIGESTION E Specialized protein that catalyzes digestive reactions 5

6 VILLI F The process of getting rid of liquid wastes 6

7 BICARBONATE G Clusters of cells in the stomach lining, make pepsin 7

8 GASTRIC GLAND H The process of getting rid of solid wastes 8

9 EGESTION I Flap that closes off the larynx when we swallow 9

10 EXCRETION J Enzyme breakdown in stomach, mouth, small intestine 10

14. Look at the diagram to the right. Which organs are shown?

15. Why are they called accessory organs?

16. Identify any three ways these organs help in chemical digestion.

17. Label the excretory system (right).

18. Where in the excretory system would you find nephrons? Why

are they important?

19. Other than the organs in this diagram, which other organs in our body help with excretion?

20. Take a look at the diagram of a pig’s digestive

system, to the right. Based on what you can see,

what can you conclude about the diet of a pig?

Explain your viewpoint, using facts from your

knowledge of the digestive system and its organs.

SUMMARY: TYING IT ALL TOGETHER

1. Throughout the course, we have seen many examples of the importance of surface area to the function and

survival of living things. Explain how surface area plays an important role at the levels of the cell, and organ,

and a system.

2. Our most important nutrient is glucose, a simple sugar with the formula C6H12O6. Each glucose has six

carbon atoms. Glucose makes starch, which is what bread is mainly made of. Using your knowledge of the

human body, trace the path of a single carbon atom from the moment you bite into a sandwich to the

moment you breathe out a molecule of CO2.

3. In this course, we learned about cells, genetics, and body systems. Use an example from our course to

show how cells, genes and a body system of your choice are all interconnected.

4. At the beginning of the course, we took a wide look at the variety of life on our planet. One of the most

basic divisions of living things is the division between unicellular and multicellular organisms.

a. How does our body show traits of both unicellular and multicellular life forms?

b. Why do you think this has given vertebrates an advantage over all other animals?
