Body System
This organ is where oxygen enters and carbon dioxide exits your body.
What are the lungs?
This molecule is known as the energy currency of the cell.
What is ATP?
List 4 criteria graphs should include
Title, x-axis, y-axis, and scale
What is the difference between independent variable and dependent variable?
Independent Variable: what is being changed in the experiment
Dependent variable: what is observed or measured.
This organelle contains DNA, which holds the instructions for building and running the cell.
What is the nucleus?
This gas is taken into the body during inhalation and is needed for cellular respiration.
What is oxygen?
This type of respiration requires oxygen to produce the most ATP.
What is aerobic respiration?
Line is change over Time
Bar graph is about categories
You are testing how the amount of sunlight affects the growth of a plant. You place identical plants in different amounts of sunlight: 2 hours, 4 hours, and 6 hours per day. After two weeks, you measure how tall each plant grows.
Identify the independent variable (IV) and the dependent variable (DV) in this experiment.
IV: Amount of sunlight
DV: Height of the plants
List one organ in the respiratory system and circulatory system
Heart and Lungs
This organelle is found in every cell and is responsible for producing energy.
What are mitochondria?
This type respiration occurs when oxygen is not available.
What is anaerobic respiration?
You record the temperature of a cup of water every 10 minutes. Which type of graph should you use to show how the temperature changes over time?
Line Graph
Does the type of fertilizer affect the number of flowers a plant produces?
Claimed IV and DV: IV = Number of flowers, DV = Type of fertilizer
Question: Are the IV and DV correctly identified? Explain.
No. The independent variable (IV) should be the type of fertilizer (what the experimenter changes), and the dependent variable (DV) should be the number of flowers (what is measured).
This body system allows movement and maintain posture.
What is the muscular system?
This type of blood is oxygen poor and flows from the body - heart - lungs. This type of blood is oxygen - rich and flows from the lungs - heart - body.
What is the difference between venous blood and arterial blood?
In this organelle, aerobic respiration mainly occurs to the produce ATP.
What are mitochondria?
You measure the growth of a plant every day for two weeks and want to show how its height changes. Which graph is best?
What is line graph?
Research Question: Does the amount of water a seed receives affect how quickly it germinates?
Claimed IV and DV: IV = Amount of water, DV = Time to germinate
Question: Are the IV and DV correctly identified? Explain.
Yes. The IV is the amount of water (what is changed), and the DV is the time it takes to germinate (what is measured).
What is the normal oxygen saturation Level? Was our marathon runner oxygen saturation level? Explain your response
95 - 100%
Yes, her blood oxygen saturation level was 98%
Explain the relationship between circulatory system and respiratory system
The respiratory system brings oxygen into the lungs and removes carbon dioxide. The circulatory system carries oxygen-rich blood from the lungs and transport carbon dioxide from the cells back to the lungs to exhale.
What is cellular respiration?
This process occurs in cells to produce ATP.
You collect data on how many books each student in your class read last month. Which graph should you use to compare the amounts?
What is bar graph?
From the yeast lab, what was the independent and deponent variable.
IV: amount of sugar
DV: height of foam and size of balloon
The ___________________ flows from the lungs - heart - body.
The _______________ flows from the body - heart - lungs.
1. Arterial Blood
2. Venous Blood
