a transform boundary because the two plates pass each other in that same plane and the blocks of rock move in opposite horizontal directions .
<span>Symbols for lipids is C and H.
It also contains Nitrogen and phosphorous. DNA or RNA their symbol is C, H, O, N, P. Protein contains both sulfur and selenium which are C, H, O, N, P. Proteins are subunits of amino-acids.
Proteins can be carriers, signaling structural and also immune responses. They are made of the nucleus.
Lipids are hydrophobic and are naturally found in the body to mean that they don't mix with water reason being they are non-polar. Lipids make up phospholipids bilayer.
DNA is supercoiled, and their backbone which is made up of phosphate and sugars groups.</span>
Lipids are macromolecules which provide insulation.
<span>A macromolecule is a large molecule. There are four groups of macromolecules: carbohydrates, proteins, nucleic acids and lipids. Lipids consist of glycerol and fatty acids and are constructed from fats, oils, waxes, phospholipids and steroids. A lipid's function is to insulate the body and provide warmth in cold conditions. It can be concluded that a person with very little body fat gets very cold easily and a person with a lot of body fat gets very warm very quickly.

Answer:
D. The total energy of a system can increase only if energy enters the system
Explanation:
According to the law of Conservation of Energy, energy can neither be created nor destroyed but can be transformed or converted from one form to the other.
A system has the same energy until there is an addition of energy externally. When energy is added, it will lead to an increment in energy. So, when work is done to the system or the system heated, energy increases.
