Organelles
Ribosome
The movement of molecules from high concentration to low concentration
Diffusion
Dependent Variable
Located in the cell membrane, these specific types of molecules act as receptors to receive chemical messages like hormones.
proteins
This body system move fresh air into the body and stale air out of the body
Respiratory system
This organelle contains genetic material and directs many cell activities
Nucleus
Osmosis
A student changes the amount of light given to identical plants and measures plant height. What is the dependent variable in this experiment
Because receptor molecules are proteins, this physical characteristic directly determines its specific function or job.
shape (structure)
Oxygen and carbon dioxide enter the bloodstream through which process?
Diffusion
1. controls passage of material in and out of the cell
2. Surround and protect the cell
3. Aids in cell Communication
Cell Membrane
This type of transport requires energy to move molecules from low concentration to high concentration
Active Transport
When completing an investigation, what is the reason you would repeat the experiment multiple times?
hese specialized cells make up nerves and use both chemical and electrical signals to help the nervous system maintain homeostasis.
Neurons
The Alveoli are responsible for gas exhange in the body in which organ?
This body system move fresh air into the body and stale air out of the body
the lungs
This organelle is the site of Cell Respiration and considered the "powerhouse o f the cell"
Mitochondria
Equilibrium, Balance
This is a variable that would be changing or testing throughout an entire investigation.
independent variable
This is the specific term for the chemical message released into the synapse by a sending cell.
Neurotransmitter
This system delivers oxygen and nutrients to the cells and tissues around the body
The circulatory system
This organelle is responsible for carrying out photosynthesis
Chloroplast
What structure on the cell membrane allows larger molecules to pass through the cell membrane
Transport protein
This group in an experiment does not get the special treatment, giving scientists a baseline to compare their results against.
Control group
if a protein is denatured, how does this affect the protein?
the structure changes which changes its function.
which two systems with together to supply oxygen to the blood and cells and remove carbon dioxide through the lungs.
circulatory system and respiratory system
