Cell are the structural and functional unit of living organisms
Answer:
The carbon atom used to build carbohydrate molacules come from carbon dioxide, the gas that animals exhale with each breath. The Calvin cycle is the term of used for the reaction of photosynthesis that use the energy stored by the light dependent the reaction ot form glucose and other carbohydrate molacules.
Answer:
Photosynthesis relies on sun, water, and CO2 for it to make food. When there are lower levels of either, the organism carrying out photosynthesis can't make as much glucose and oxygen. This in turn harms the organism.
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.
