The only star in our solar system is the Sun.
Two functions of the skeleton system are:
- It is a support structure for the body
- It provides protection our internal organs
I would say the answer is either A or B, the Law of Consevation of Energy states that,"<span>the total energy of an isolated system remains constant</span>" so this energy isn't destroyed, it's simply useless. When we use energy to run, our energy is released as heat, so I would assume that it is the same for other creatures. Let me know if this helps.
Answer:
Bacteria.
Explanation:
Virus, Parasite, and Fungi all use a host for pure personal gain. Some strains of bacteria are beneficial, and are ingested regularly in the form of probiotics.
Endothermic change
Explanation:
Enthalpy changes are heat changes accompanying physical and chemical changes. There are two types of enthalpy changes: Endothermic change and exothermic change.
In an endothermic change, heat is absorbed from the surround and hence the surrounding becomes colder at the end of the change.
A change that leaves the reaction colder is an endothermic change.
