How might the concentration of a substance affect its avility to harm an orgainsm?
Higher concentrations of a harmful substance can increase the likelihood and severity of harm to an organism. This is because higher concentrations mean more of the substance is available to interact with the organism's cells and tissues, potentially causing damage or disrupting normal physiological processes. Additionally, higher concentrations may overwhelm the organism's detoxification or elimination mechanisms, making it harder to remove the harmful substance from the system.

How does the Concentration gradient of a substance affect the movement of that substance and the expenditure of energy?
A concentration gradient of a substance drives the movement of that substance from an area of high concentration to an area of low concentration. The steeper the concentration gradient, the faster the movement of the substance, requiring less energy to transport it. If the concentration on both sides of the gradient is equal, there is no net movement of the substance.
Can the concentration of the substance change if it is a gas?
Yes, the concentration of a gas can change due to factors such as temperature, pressure, and volume. These changes can affect the number of gas molecules in a given volume, thus altering the concentration of the gas.
What are two secondary factors that affect solute diffusion?
The primary determing factor would be the size of the substance
What happens when you dilute a substance?
Concentration of acid will decreases on dilution. Concentration means amount of 1 substance per unit amount of another substance in which 1st substance is dissolved or mixed. So if u increase the solvent( 2nd substance) i.e., on dilution, then the ratio '1st substance per unit 2nd substance' decreases. Hence concentration decreases.
What is a lapse concentration?
Lapse concentration refers to the change in the concentration of a substance—often in relation to altitude or pressure—typically observed in the atmosphere. As altitude increases, the concentration of gases like oxygen decreases, which can affect breathing and other physiological processes. This concept is essential in fields like meteorology and environmental science, as it helps explain phenomena related to air quality and climate.
What are some factors that affect enzyme speed?
Substance concentration, enzyme concentration, temperature and PH level
How does the Concentration gradient of a substance affect the movement of that substance and the expenditure of energy?
A concentration gradient of a substance drives the movement of that substance from an area of high concentration to an area of low concentration. The steeper the concentration gradient, the faster the movement of the substance, requiring less energy to transport it. If the concentration on both sides of the gradient is equal, there is no net movement of the substance.
Does the presence of another substance affect the rate of diffusion?
Yes, the presence of another substance can affect the rate of diffusion. Factors like the nature of the substance, concentration gradient, temperature, and molecular size can influence how quickly a substance diffuses in a system.
When is a substance most likely to diffuse into a cell?
If there is the concentration of substance inside the cell is lesser than outside and cell membrane is permeable to the substance.
How does substance dependence affect a person?
A substance-dependent person must have a particular dose or concentration of the substance in his or her bloodstream at any given moment in order to avoid the un-pleasant symptoms associated with withdrawal
Can the concentration of the substance change if it is a gas?
Yes, the concentration of a gas can change due to factors such as temperature, pressure, and volume. These changes can affect the number of gas molecules in a given volume, thus altering the concentration of the gas.
What is the difference between a diluent and a dilutant, and how do they affect the concentration of a solution?
A diluent is a substance used to dilute a solution, while a dilutant is a substance that is already present in a solution and contributes to its dilution. Both diluents and dilutants decrease the concentration of a solution by adding more solvent to it.
What is the difference between molarity and concentration, and how do they affect the properties of a solution?
Molarity is a specific type of concentration that measures the amount of a substance in a given volume of solution. Concentration, on the other hand, is a broader term that refers to the amount of solute in a given amount of solvent. Both molarity and concentration affect the properties of a solution by determining its strength, reactivity, and behavior in chemical reactions.
What are two secondary factors that affect solute diffusion?
The primary determing factor would be the size of the substance
What happens when you dilute a substance?
Concentration of acid will decreases on dilution. Concentration means amount of 1 substance per unit amount of another substance in which 1st substance is dissolved or mixed. So if u increase the solvent( 2nd substance) i.e., on dilution, then the ratio '1st substance per unit 2nd substance' decreases. Hence concentration decreases.
What changes when the amount of a substance changes?
When the amount of a substance changes, it can affect the concentration, density, and reactivity of the substance. In chemical reactions, changing the amount of a substance can also impact the equilibrium position and the rate of reaction. Additionally, changing the amount of a substance can influence its physical properties, such as melting point, boiling point, and solubility.
How does an increase in total energy of the particles in a substance affect the thermal energy of the substance?
