The Phone Guy refers to Mangle as "he/him," yet Mangle also appeared in the Custom Night setting known as "Ladies Night." Scott Cawthon finally said, "Yes," when asked about Mangle's gender.
Who is mangles?They have been addressed using the pronouns "he," "he," and "her." Bonnie is regarded by Scott as the most frightful animatronic.
While creating Five Nights at Freddy's, he frequently had nightmares about Bonnie, and while creating Bonnie's artificial intelligence, he even unintentionally caused himself jump scares.
According to one explanation, it is based on Mangle from the Five Nights at Freddy's video game series and is a jumbled mass of different genders with a charming horror style. This definition fits under the category of aesthetic gender.
Therefore, Scott Cawthon finally said, "Yes," when asked about Mangle's gender.

In an exothermic reaction, chemical energy is converted to _____.
1.thermal
2. mechanical
Answers
Because exothermic is having to do with energy
The chemical reactions are generally of many types. The exothermic and endothermic reactions are important among them. In an exothermic reaction the chemical energy is converted to thermal energy. The correct option is 1.
What is exothermic reaction?The chemical reactions which proceed with the evolution of heat energy are defined as the exothermic reactions. The chemical reactions which proceed with the absorption of heat energy are called endothermic reactions.
In an exothermic reaction, system loses heat to surroundings. Since heat is given out in exothermic reactions, the enthalpy of the products will be less than that of the reactants.
In exothermic reaction, q will be negative and the enthalpy change will be also negative. In this reaction chemical bonds are broken and new bonds are formed. The chemical energy is converted to kinetic energy which is released as heat.
Thus exothermic reaction releases thermal energy.

Drinking water has two sources. It can come from surface water, such as reservoirs or rivers. Or it can come from groundwater where it either naturally surfaces in a spring or where it must be pumped to the surface from a well. Where does your drinking water come from?
Answers
82% of drinking water supplies in Ireland are sourced from surface water (rivers and lakes) and 18% comes from groundwater - it depends where you live (quick g00gle search should answer you question)
Our drinking water comes from the underground sources like wells, hand pumps, etc.
What are the sources of water?Sources of water are the places from where the water comes to earth for the uses.
In our houses drinking water comes from the underground sources, through the wells, hand pumps, etc. From that source we get natural water for the drinking purposes.
Hence we get water from underground sources.

Answer:
...
Explanation:
find density of salt solution 585g/500cc = 1.17g/cc
leaves density = 1.25g/cc, stars density = 1.12g/cc
Stars float, leaves sink. since everything is in g/cc, you do not have to worry about the info 1ml=1cc.
density = mass / volume.
density of salt solution = 585g(mass)/500cc(volume)

describe what is happening to rock climbers’ body systems and cells at the small scale.
Answers
Answer:
It is being pressured!
Explanation:
The pressure point changes so people aren't used to that certain pressure
As a rock climber climbs higher, the systems and cells experience a decrease in pressure.
Pressure decreases with height. Hence, the higher you go, the lesser the pressure becomes and this may have obvious implications on the cells and systems of a rock climber.
As air pressure decreases at higher altitude, a rock climber may find it difficult to breathe because of the sudden decrease in air pressure hence the respiratory system is affected.
Prolonged exposure to high altitudes may lead to a decrease in the amount of oxygen in blood causing the heart to pump harder.
