Answers
Answer:
If your body manages to maintain homeostasis, then it means everything is in order, and you are in a healthy state. However, getting sick would indicate that your body conditions are not stable. This happens when the homeostasis is disrupted due to the interference of pathogens such as viruses and bacteria; for example, catching a flu virus would cause you to have a fever, cold, sore throat, and muscle aches. These symptoms eventually weaken your body and prevent you from performing your daily life functions.
The homeostasis has been affected while getting sick due to a change in temperature with disturbed electrolyte balance.
Homeostasis has been the ability of the body to maintain the equilibrium balance of the electrolytes, and elements for the proper functioning of the system.
The homeostasis has been maintained with the temperature and balance of the components in the preset limit. However with the change in the homeostasis results in the change in the balance and functioning of the organs.
While getting sick, we have changes in the body temperature along with electrolyte dis-balance. This results in disturbed homeostasis.

How does the temperature of water affect its ability to hold oxygen?
Answers
Answer:The solubility of oxygen and other gases will decrease as temperature increases 9. This means that colder lakes and streams can hold more dissolved oxygen than warmer waters. If water is too warm, it will not hold enough oxygen for aquatic organisms to survive.

What are some ways your body regulates the increase of body temperature that also occurs when exercising?
Answers
Answer:
Doing push-ups
Explanation:
When you workout you get hot so the tempeture of ur body increase.
Some ways by which your body regulates the increase of body temperature that also occurs when exercising are evaporation of sweat and skin blood flow.
What is effect of exercising on body temperature?
Our muscles quickly deplete stored energy when you start exercising. To make more energy, muscles combine oxygen with adenosine triphosphate or ATP. This process creates heat energy as a byproduct. Muscles generate the most heat because they produce so much energy.
Extra heat raises your body temperature, so your body needs to eliminate heat as quickly as possible.
Therefore, some ways by which your body regulates the increase of body temperature that also occurs when exercising are evaporation of sweat and skin blood flow.

Answers
Metal is a really good conductor and is used in different electronics. It is also ductile, meaning it can be pulled into a thin wire.
Hope you have a wonderful day:)
Wire is typically made out of metal because metal is ductile and conducts electricity.
Ductility is the property of metal which makes it easy to be stretched into wire when drawn without breaking. This is a great feature for wires.
Conductor of electricity : The ability for a material to allow electricity to pass through it with ease shows it is a good conductor of electricity.This is also a great feature for wires.
The transition metal, copper is usually preferred for the manufacture of electrical wires This is because apart from being thermal resistant and cheap, it is very ductile and a good conductor of electricity.
