Chapter 7 Test Review : Cells are Busy Places
Along with studying the questions below make sure you check out the “notes” and “jeopardy” review on the classroom website.
1. Compare the photosynthesis equation to the equation for respiration. What do you notice?
2. Name three ways that animals lose water.
- Urination (Ryan Z.)
- Transpiration (Ryan Z.)
- Perspiration
(Ryan Z.)
3. What type of nutrient is glucose (carbohydrate, protein, nucleic acid or lipid)?
carbohydrate(Brittani M)
4. What are other sources of carbon dioxide (besides animals exhaling)?
-
Combustion of fossil fuels (Nick R)
-
Mineral production (Nick R)
-
Metal Production (Nick R)
5. What are some reasons the process of photosynthesis is important to life on Earth?
Photosynthesis is important because it is the process in which plants make their food to survive.(Brittani Miller)
Because photosynthesis takes in carbon dioxide and produces oxygen for us to breath. (Ryan Z.)
6. Describe how Light Dependent & Light Independent Reactions of photosynthesis are different in a plant. What products are produced in each? Check your notes.
7. Describe what happens in a person’s muscles after strenuous physical activity and why this occurs:
The person's muscles burn because of hydorgen ions build up in the muscles while exercising. (Ryan Z.)
8. Which process leads to a net increase in energy in our ecosystem?
9. What pigment is crucial for absorbing light and thus allowing photosynthesis to occur? Where is this pigment found in a plant cell?
Chlorophyll, it is found in Chloroplasts. (Zac C.)
For the following infectious diseases, write down three main facts about each.
10. Malaria
- Malaria is spread by bacteria transferred by the mosquito. (Nick R)
- Malaria kills more than 3 million people and affects another 300 million each year. (Nick R)
- If you are traveling to Mexico and Central America, Haiti, the Dominican Republic, South America, sub-Saharan Africa, the Indian subcontinent, Eastern Europe, Asia, the Middle East, Papua New Guinea, Vanuatu, or the Solomon Islands, you could be at risk for malaria. (Nick R)
11. West Nile Virus
* People in the United States can get this virus(brittani miller)
* the virus is actually spread by certain species of mosquitoes, when the mosquito bites a bird infected with west nile virus the mosquito gets infected, then when it bites you then you become infected.(brittani miller)
*West Nile virus transmission occurs mostly during warm weather, when mosquito populations are active(brittani miller)
12. Polio
1)A viral disease
2)Enters body through the mouth from contaminated hands.
3)NO Cure
4)Fever, stiffened back, fatigue musle pain are just some sypmtoms. (Zach Overhauser)
13. Small Pox
1)A virus
2)Enter's body through the mouth where it then makes it's way toward the lungs
3)Extensive rashes, high fever, bumps all over skin are some symptoms. (Zach Overhauser)
14. Tuberculosis
15. Cholera
16. Lyme Disease
17. Giardia
18. Hanta Virus
19. Hepatitis
20. Explain what a vaccine is (in general terms) and how/why it works.
A vaccine is a shot you recive with a minor virus that will attack your immune system so it can reconize the virus
and build up white blood cells to fight that virus if a greater version comes. (Ryan Z.)
21. Describe the basic steps of aerobic cellular respiration in both plant and animal cells and where this process occurs.
22. Which process produces the most adenosine triphosphate (ATP)?
Aerobic (Zac C.)
23. Explain what a kilocalorie is and why it’s important to humans.
- A unit of heat equal to the amount of heat required to raise the temperature of one kilogram of water by one degree at one atmosphere pressure; used by nutritionists to characterize the energy-producing potential in food. (Nick R)
24. Explain the relationship between consumers and producers, herbivores, carnivores, omnivores, autotrophs and heterotrophs.
herbivores= organism that only eats plants(brittani miller)
carnivores=organism that eats meat(brittani miller)
omnivore=organism that eats both meat and plants(brittani miller)
autotrophs=animal that makes its own food(brittnai miller)
heterotrophs=organisms that rely on other organisms for food(brittani miller)
