When body temperature rises a center in the brain initiates physiological changes to decrease the body temperature is an example of negative feedback or positive feedback?
This is a very good example of negative feedback.
What are 3 factors which can influence the activity of an enzyme?
Three factors that can influence the activity of an enzyme are temperature, pH, and substrate concentration. Changes in these factors can alter the enzyme's shape and affect its ability to catalyze reactions effectively.
Some factors that may influence enzyme activity?
A low temperature can slow down enzyme activity and high temperatures can denature an enzyme making it unusable. pH levels also affect enzyme activity. Every cell has an ideal temperature and pH
Factor that effect enzyme function?
Factors that can affect enzyme function include temperature, pH levels, substrate concentration, enzyme concentration, and the presence of inhibitors or activators. Changes in any of these factors can alter the activity of enzymes and either increase or decrease their ability to catalyze reactions.
How temperature and pH affect enzyme activity?
Temperature And Enzyme Activity: Increasing temperature means the molecules gain more kinetic energy and move faster resulting in more chances of successful collisions of enzymes and substrates forming enzyme-substrate molecules.
Changes in pH or temperature decrease enzyme activity because bonds break and the enzyme returns to its tertiary structure?
Changes in pH or temperature can disrupt the interactions that maintain the enzyme's specific shape, leading to denaturation and loss of enzyme activity. This is because enzymes are sensitive to changes in their environment, and alterations in pH or temperature can affect the enzyme's active site conformation, preventing it from binding to the substrate effectively.
Which changes would changes would correspond to a decrease in a star's absolute brightness?
A decrease in the star's temperature
What are the changes that increases pressure?
- a decrease in volume- the increase of temperature
What does temperature decrease on?
Temperature decrease is often associated with the slowing down of molecular movement in a substance. This can lead to changes in physical states, such as the solidification of a liquid or the condensation of a gas. Temperature decrease can also affect chemical reactions by decreasing reaction rates.
What happens to volume during phase changes?
Volume increases with increase in temperature, and decreases with decrease in temperature.
Does the temperature of the atmosphere decrease steadily with increasing altitude?
Yes it does but the rate changes depending on what you come across. But yes, it does decrease.
When the body temperature rises a center in the brain initiates physiological changes decrease the body temperature. this is an example of?
Negative Feedback
How would you describe the changes that happened to the material when cooled?
Changes in physical properties: cooling is temperature decrease caused by heat exchange
What do chemical bonds have to do with a temperature change?
Chemical bonds store energy, and breaking or forming these bonds can either release or absorb energy, which can lead to a temperature change. When bonds are formed, energy is released, resulting in an exothermic reaction that can increase the temperature of the surroundings. Conversely, breaking bonds requires energy input, resulting in an endothermic reaction that can decrease the temperature of the surroundings.
What does your bmr do as you age?
As you age, your Basal Metabolic Rate (BMR) tends to decrease. This decrease is primarily due to factors such as loss of muscle mass, hormonal changes, and overall decrease in physical activity levels. It's important to adjust your calorie intake and activity level to accommodate for this decrease in BMR to maintain a healthy weight.
An activity which changes the temperature to more than 100 degrees Fahrenheit?
Go to the beach
What is the process of breaking rock into small pieces with ice water temperature changes and chemical reactions?
Weathering.
