Food Web
Which organisms from the food web can produce their own food?
Phytoplankton
Name 2 of the body systems represented by the organs shown in the diagram.
circulatory, respiratory, muscular
Using model 2, what is the genotype of the mother?
Hh
Which cell came from Samantha’s dog?
sample 1
Which body system is being shown in the images?
skeletal
Though it is not shown in the diagram, this is the main source of energy for all the living things found in the food web.
the sun
Which two body systems shown in the diagram work together to deliver oxygen to cells for cellular respiration?
circulatory and respiratory
Using model 2, do the siblings have the same phenotype? Why or why not?
No. 25% is normal hemoglobin, 50% are carriers, and 25% have sickle cell anemia.
What do the plant and animal cells have in common?
both have nucleus, cytoplasm, cell membrane, mitochondria
What process causes species to change over time?
evolution
Think about the flow of energy in the food web. Where does the Round Goby get its energy from?
mussels
Inside the cells, oxygen (from the respiratory system) combines with nutrients (from the digestive system) to make energy for the soccer player. What organelle in the cell is responsible for this?
The offspring were produced through sexual reproduction. How much genetic information did the father pass to the offspring? (All? Some? None?)
half
The DNA is found in the control center of the cell. Which is the control center?
nucleus
Similar bone patterns in different animals are evidence for what idea?
common ancestor
Which pair of organisms in Lake Erie displays a competitive relationship?
white perch and round goby ...or... white perch and emerald shiner ...or... mussels and krill
Arrange the following levels of body systems in order of increasing complexity.
cardiac tissue cell heart circulatory system
cell --> cardiac tissue --> heart --> circulatory system
Look at the difference in DNA in model 1. What is being demonstrated in the image on the right?
a mutation
What is the cell membrane responsible for?
controls materials moving in and out of the cell
What evidence in the diagram suggests these animals are related?
similar bone structure
What has severely affected the population of some species in the Lake Erie Food Web?
pollution, habitat degradation, invasive species, and overfishing
Using the graph, describe the relationship between the amount of time playing soccer and heart rate.
As the amount of time playing soccer increases, the heart rate increases.
If a person with sickle cell anemia (hh) were to mate with a carrier (Hh), what is the chance the offspring will have sickle cell anemia? (Grab a pencil and paper!)
50%
What can sample 2 do that sample 1 cannot do?
photosynthesis
Look at the common ancestor compared to the other organisms in image 2. The difference in bone structure suggests that, over time, organisms become more ___.
diverse, complex
