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.
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.
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
Is an enzymes function dependent on temperature and pH?
Every enzymes has its own optimum pH and temperature, where it shows higher activity (pH:it is very specific; temperature:mostly not more than 30-37degree C). Above or below this situation the enzymes activity may differs exponentially due to the biochemical changes.
True or false Changes in chromatin structure and histone-DNA binding are associated with changes in gene activity?
there is research this is true
Changes in pH or temperature decrease enzyme activity because bonds break and the enzyme returns to its tertiary structure?
Changes in pH or temperature decrease enzyme activity because bonds b reak and the enzyme returns to it's PRIMARY structure. (not tertiary)
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 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
An activity which changes the temperature to more than 100 degrees Fahrenheit?
Go to the beach
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.
What changes gas solubility?
Solubility can increase and decrease with temperature variations and changes, Pressure can increase and decrease solubility with difference pressure variations, the nature of the gas and the nature of the solvent as well chance the solubility of the gas.
What is the process of breaking rock into small pieces with ice water temperature changes and chemical reactions?
Weathering.
If the outdoor temperature increases by 10c what will happen to a reptiles body temperature?
Reptiles are cold blooded and require the atmospheric heat to regulate their internal body temperature. If the outside temperature were to decrease by 20 c the internal temperature of the reptile would decrease 20C.
