What organ of the endocrine system controls cell metabolic rate?
thyroid
Increasing the temperature of the system increases the in the system making it more likely that two particles will collide with thereby increasing the?
average kinetic energy, enough energy, reaction rate
What happens to the rate constant as energy increases?
The rate constant decreases.
Why does pump head decrease as volume flow rate increases?
Pump head decreases as volume flow rate increases due to the principle of conservation of energy. As the flow rate increases, the speed of the fluid also increases, resulting in higher kinetic energy. This leads to a drop in pressure and pump head as the energy is converted into kinetic energy instead of potential energy.
What statement describes one possible interaction between the endocrine and respiratory systems?
The respiratory system brings the endocrine system oxygen. A small fraction of your breathing is also controlled by the endocrine system. A response to stress in the epinepheran in the endocrine system which can cause heavy breathing.
How does stress affect your nervous system?
Answer this question… A. signals musculoskeletal system to cause rapid and uncontrollable movements B. signals digestive system to stop digesting food C. signals endocrine system to produce hormones to elevate heart and breathing rate D. signals the respiratory system to reduce the breathing rate
Which body system is effected by the removal of the throid gland?
The endocrine system is affected by the removal of the thyroid gland. The thyroid gland plays a key role in regulating metabolism, energy levels, and various bodily functions by producing thyroid hormones. Removal of the thyroid gland may lead to hormonal imbalances and can impact overall health.
Which hormones are involved in emotion and stress?
Under fear, surprise, or stress, your endocrine system releases adrenaline to help you react to the situation in your environment.
Describe what can happen to the reaction rate of a system that is heated then cooled?
Heating a system typically increases the reaction rate as the molecules have more energy to react. Cooling the system will usually slow down the reaction rate as the molecules have lower energy levels, leading to fewer successful collisions between reactant molecules.
How factors affect rates of physical change?
-Reactant Concentration • The greater the concentration of reactants (the more particles per unit volume), the greater will be the number of effective collisions per unit time, and therefore, the reaction rate will generally increase. • For zero order reactions, however, the reaction rate is not dependent on the concentration of reactants. Increasing the reactant concentration will have no effect on the rate. -Temperature • The reaction rate will increase as the temperature of the system increases. As the temperature increases, the reactant molecules have more energy. They thus find it easier to climb the energy barrier to the reaction (the activation energy). -Solvent • The reaction rate will increase as the temperature of the system increases. As the temperature increases, the reactant molecules have more energy. They thus find it easier to climb the energy barrier to the reaction (the activation energy).
Do energy drinks affect heart rate?
Yes, caffeine increases your heart rate.
When would adrenaline be secreted into the endocrine system?
Adrenaline is secreted by the adrenal glands into the bloodstream in response to stress, fear, or excitement to prepare the body for the "fight or flight" response. This hormone increases heart rate, boosts energy levels, and enhances focus to help the body respond quickly to perceived threats.
