Prokaryotes are the Earth`s firs living things. This are the simplest life forms exhibiting ( showing ) cellular structures.
They exist in 2 major forms:
- Eubacteria ( most of the common bacteria that are found everywhere ),
- Archaebacteria ( ancient bacteria that live in very extreme conditions ).
Answer: Prokaryotes.
The three changes of state during which energy is absorbed are:
1. Change from solid to liquid - Melting.
2. Change from liquid to gas - Vaporization
3. Change from solid to gas - Sublimation
All these changes of state require heat energy to break the attractive forces that hold the particles of the molecules together, so that they can move into more disorderly states. For instance, when heat is applied to a solid, the solid absorbs the heat and use it to break the attractive forces that are holding the molecules of the solid together. At a particular temperature, the attractive forces will be completely overcome and the solid framework will collapse, thus leading to the melting of the solid.
The fermentation of ethyl alcohol is a biological process which involves the breakdown of sugars such as glucose, fructose and sucrose into the cellular energy. The cellular energy produced in the form of ATP. This fermentation reaction produces the byproduct’s mainly as ethyl alcohol and carbon dioxide. Hence the correct answer is carbon dioxide and ethyl alcohol.
<span>Rice pudding would be an example of a heterogeneous mixture.
A heterogeneous mixture means that different constituents of a mixture can be identified. Rice pudding consists of rice suspended in a cream. It is possible to identify the grains of rice and the creamy part of the mixture.
A homogeneous mixture looks the same throughout--you cannot identify individual parts or ingredients. The parts of a homogeneous mixture are said to be uniformly distributed. Rainwater and air are examples of homogeneous mixtures.</span>
