Answer:
Too be specific a Plant Cell stores water for health ans glucose (aka) sugar for energy, which is called Vacuole
Answer: the main function is to control what goes in and out of the cell. It is made of a double layer of lipids (fats) imbedded with odd-looking protein molecules. Because it is a fat, only some things that are very tiny, like water and oxygen pass through this part.
Explanation:
A theory explaining the structure of the earth's crust and many associated phenomena as resulting from the interaction of rigid lithospheric plates which move slowly over the underlying mantle.
C. Africa
Africa’s projected population graph has the greatest distance between its beginning and ending height on the graph out of all the continents.
solution:
Thermodynamically favorable reaction is the products, because the reaction occurs spontaneously, without the need for energy to be added.
Because a reaction is thermodynamically favoured does not mean that it will be a fast reaction. So 'yes' they always proceed but possibly infinitesimally slowly. Temperature is the most common way of quickening a reaction. Of course a catalyst also does so but this generally by changing the way the reaction occurs, i.e. the mechanism is different using a catalyst but the product is the same. Enzymes are natures catalysts, in synthetic chemistry (and in you car exhaust) metal based compounds are often used.
All reactions have an activation energy EaEa between reactants and products and a small increase in the size of this can slow a reaction exponentially. Experimentally, the rate constant is generally found be of the form k=k0exp(−Ea/RT)k=k0exp(−Ea/RT), which is the Arrhenius equation, with R the gas constant and T the temperature in Kelvin
