So u get a codon chart it'll look like a circle with a bunch of letters. Then you use the letters u are given for every dash such as UCU and you go biggest to smallest letter until you hit an amino acid or stop then what you write down is that amino acid you hit. For an example, we'll use UCU. You go to the big letter U inside that big U will be a smaller C and inside that C will be a smaller U which leads to an amino acid or a stop codon. And you do this with every group of 3 letters. If one is missing it stops prematurely and if there is an extra when it may have a mutation. I hope that helped! If not there are YouTube videos out there that can help.

The animals who live in those habitats have adjusted to the local temperature so changing the climate drastically, may upset the living organisms there:)
        
                    
             
        
        
        
Answer:
i dont  think i can explain it easy sorry
Explanation:
The first law, also known as Law of Conservation of Energy,Thermal energy is the internal energy of an object due to the kinetic energy states that energy cannot be created or destroyed in an isolated system. | Nuclear energy originates from the splitting of uranium atoms a process called fission. This generates heat to produce steam, which is used by a turbine generator.
then the chemical bonds are broken, | the potential energy is released in the form of kinetic energy or energy of motion and heat or non useable energy. The kinetic energy is used to do work. | Objects have mechanical energy if they are in motion and or if they are at some position relative to a zero potential energyposition for example, a brick held at a vertical position above the ground or zero height position. A moving car possesses mechanical energy due to its motion 
The second law of thermodynamics states that the entropy of any isolated system always increases.
