The new combination is called a mixture.
In mixtures, since the substances are not chemically combined together, they still remain their own physical and chemical properties, and can be separated by simple physical methods such as filtration or distillation.
On the other hand, if the two or more substances are combined where they get new properties, the new combination will be called a compound. They cannot be separated by physical methods, but chemical methods such as heating or electrolysis.
<em>A conclusion that can be drawn about the movement of life to land is that;</em>
B.) As land plants became more complex, animal life did as well.
<u>The plants have also adapted to reduce the water loss across cell walls. This is made possible by waxy cuticles.</u>

Answer:
Boat conformation cis 1,4-dimethyl cyclohexane has the highest energy.
Explanation:
From the conformations, the boat conformation cis 1,4-dimethyl cyclohexane is least stable due to the fact that two methyl groups are located in opposite direction to each other, this leads to the production of a higher strain. Similarly, Chair conformations appear more stable than boat conformation. Hence, energy is inversely proportional to stability. As a result of the aforementioned, boat conformation cis 1,4-dimethyl cyclohexane has the highest energy.
