The arrow indicates that the cell membrane is carrying out the process of
respiration
diffusion
cell recognition
active transport
State one reason why a glucose molecule is more likely than a sucrose molecule to diffuse through an artificial membrane.
Glucose is larger than sucrose
Sucrose is too large to pass through the cell membrane
Sucrose is too small to pass through the cell membrane
The size of the molecule does not make a difference
A student was setting up beakers that contained different solutions in order to conduct a laboratory investigation, but the next day he could not tell which beaker contained the starch and water mixture. In order to fi nd out which beaker contained starch, he took a small sample from each of the beakers and conducted a test for starch on each of them.
Describe the test for starch that the student should use and the result that would indicate the presence of starch.
Add glucose indicator and heat to see if there is a color change
Add starch indicator and see if it turns amber
Add starch indicator and see if it turns navy blue/black
Add glucose indicator to see if it turns black
An ameba is a single-celled, heterotrophic organism. In order to meet its energy needs, it relies directly on the interaction of which cell structures?
chloroplasts and the cell membrane
the cell membrane and mitochondria
nucleus and ribosomes
vacuoles and the nucleus
Which cell structure plays a direct role in the release of this chemical from the cell?
nucleus
chloroplast
ribosome
cell membrane
Based on these results, it can be concluded that the specifi c protein that was added to the samples was
a salt solution
a pancreatic hormone
a new indicator
a biological catalyst
A class carried out an experiment to test the effect of rest time after exercise on the breathing rate. Each member of the class ran up and down stairs for 60 seconds. After exercising, they rested. The students then measured their rate of respiration by counting the number of inhales and exhales per minute for 7 minutes. The class then averaged their data.
What is the dependent variable?
Amount of excercise
Amount of Breaths
How many times they ran up the stairs
The time

actively transport molecules in an organism
diffuse water across a membrane
move molecules from a high to a low concentration
balance the nutrients in an ecosystem
What organelle is this?
Mitochondria
Chloroplast
Ribosome
Vacuole
What process occurs here?
Photosynthesis
Respiration
Active Transport
Diffusion

If body temperature is too high, some blood vessels increase in size and sweat glands will excrete sweat, resulting in a lower body temperature. These changes are an example of
a learned behavior
feedback mechanisms
an inherited disorder
genetic mutations
One primary function of the cell membrane is
regulating the flow of simple sugars into or out of the cell
synthesizing substances by breaking down cell organelles
storing carbohydrates, water, and starches for future use
digesting carbohydrates, fats, and protein
What is a valid hypothesis
Does UV light impact bacterial growth?
More UV light will make bacteria grow less
Does UV light impact plant growth?
More UV light makes the plants grow more
What is the independent variable?
UV light
Plant Growth
Bacterial Growth
Number of Set Ups
What is the dependent variable?
UV light
Plant Growth
Bacterial Growth
Number of Set Ups
What are 2 variables that should be kept the same?
UV light
Amount of Time
Bacterial Growth
Number of Set Ups
Which statement best describes how nutrients enter the root cells of the onion plant?
Only nutrients needed by the plant enter root cells.
The nutrients usually move from an area of high concentration in the soil to an area of low concentration in root cells.
Nutrients always move into the plant cells by active transport.
The nutrients always move from an area of low concentration in the soil to an area of high concentration in root cells.
