Answer: Cell differentiation can be defined as a process in which the less specified cell is converted into the more specified cell. The cells at the embryonic stages is less specialized and during the process of development it becomes more specialized and this process is regulated by gene expression. The gene expression involves a specific group of genes which is expressed or suppressed, that decides the function of the cell.
A fertilized egg shows a single cell which is non-specialized that will become complex and will turn into a multicellular organism by cell differentiation.
This is the reason the adult rabbit looks so different from the single fertilized egg.
A reaction in which energy is absorbedfrom the surroundings is called an endothermic reaction. In endothermicreactions the enthalpy of the products is greater than the enthalpy of the reactants. Because reactions releaseor absorb energy, they affect the temperature of their surroundings. If reactant molecules in a particular reaction have more energy than the product molecules, then energy is released to the surroundings in the form of heat and light. And when this happens, the reaction is usually called an exothermic reaction.
On the other hand, if the product molecules have more energy than the reactants, then the reaction absorbs energy from the surroundings. And when this happens, the reaction is usually called an endothermic reaction.
Answer:Prokaryotes play several roles in the nitrogen cycle. Nitrogen-fixing bacteria in the soil and within the root nodules of some plants convert nitrogen gas in the atmosphere to ammonia. Nitrifying bacteria convert ammonia to nitrites or nitrates. ... Denitrifying bacteria converts nitrates back to nitrogen gas.
