Why do cells need to maintain an optimal internal environment?
Cells need to maintain an optimal internal environment to ensure that essential biochemical reactions can occur efficiently. Any deviation from the optimal conditions can disrupt these reactions, leading to cellular dysfunction and potential damage. Maintaining homeostasis allows cells to function properly and support overall health and survival.
Why do living things need both endothermic and exothermic reactions in their bodies?
Living things have cellular reactions which involve both reactions in the process. Endothermic reactions help the body conserve energy or contain it. Exothermic reactions help the body produce energy.
How are the dark reactions that occur in plants dependent on the light reactions?
The dark reactions that occur in plants are dependent on the light reactions because the dark reactions need ATP and NADPH. ATP and NADPH are energy molecules that dark reactions need to do their job.
Why do you need toes?
Toes help with balance and walking by providing stability and support. They also assist in pushing off the ground when moving and help with maintaining proper posture. Additionally, toes play a role in feedback to the brain about the surrounding environment.
What organs are involved in homeostasis?
Homeostasis is the body's way of regulating internal conditions: * Core body temperature - to prevent temperatures going above or below 37 degrees Celcius, vasoconstriction or vasodilation takes place in the bloodstream to reduce or enlarge the size of blood vessels near the surface of your skin. Muscles will rapidly relax and contract if you are too cold - shivering. Also your hair will stand on end in an effort to trap air - a good insulator. * Blood sugar levels - the pancreas secretes insulin to convert glucose into glycogen * Water and ion content - Water is taken into the body by eating, drinking and as a by-product of respiration. The hypothalmus in the brain will send negative-feedback signals to tell us if we are thirsty, or if we need to excrete waste, via the kidneys and bladder.
How are these last two chemical reactions alike different?
The question is quite vague, as there are many chemical reactions and none are specified, so the two chemical reactions must be specified before an answer can be given.
After the brain has ordered the body to act what does the brain do about the consequences of the actions?
The brain evaluates the consequences of the actions through signals received from the body and external feedback. It processes this information to determine whether the actions were successful or need adjustment. This helps the brain learn from experience and make better decisions in the future.

A feedback mechanism does not need?
A feedback mechanism does not need to be complex to be effective. It should be clear, specific, timely, and constructive to facilitate improvement. Feedback also does not need to be one-way; open dialogue and communication are essential for the feedback process to be meaningful and beneficial.

Do chemical reactions need heat to start them off?
Endothermic reactions need heat.
Why do you need a museles in your brain?

What would be an example of Intrinsic feedback in sport?
Intrinsic feedback in sport would be you personality criticizing your performance giving mental feedback in what you can improve on in situations. this is used by every sports person in every sport because every sports person will need to develop and build there performance personally without the help of a coach!!
