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:
When laws are made to protect a species, it is made to stop human interference. Often natural factors also are the reason for a species decline, some of these factors may include, habitat change, climate change and may also be a disease going through the species. In order to truly save a species you would have to isolate them in an area and make sure they are all healthy and the habitat does not change. The only issue with that is, they could lose some of their natural instincts such as hunting or being scared of humans. So a law may not be enough to save a species because there may also be many natural factors interfering with a species survival.

Answer:
The motion of an object is defined by its change in position and direction.
Explanation:
Motion is the action of changing location or position. Motion is usually brought about by an external force.
Kinematics is the study of motion alone without regard to the forces or energies involved.
The various types of motion include:
Translational motion : This is motion that occurs along a straight line. For example, a car travelling on a straight road.
Rotational motion: this motion that occurs in a circular path. For example, movement of the earth round the sun.
Oscillatory motion: this is a periodic or to and fro motion that occurs between two points. For example, a swing or a simple pendulum.
Random or zigzag motion: This is motion that occurs in no particular pattern or direction. for example, the movement of dust particles.
