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. </span>
Answer:
Option (A).
Explanation:
Cell membrane or plasma membrane is made up of lipids and proteins with the small amount of carbohydrates are attached to it. This membrane maintains fluidity and separate cell's environment.
Small non polar and uncharged molecules can easily pass through the cell membrane by the process of diffusion. Carbon dioxide and water are small molecules that can easily pass through the membrane.
Thus, the correct answer is option (A).
<h2>Answer:</h2>
Lysosomes are organelles that contain digestive enzymes (acid hydrolases). They digest excess or worn out organelles, food particles, and engulfed viruses or bacteria. The membrane surrounding a lysosome prevents the digestive enzymes inside from destroying the cell.
As it turns out, our tears do contain some magic, namely the powerful enzyme lysozyme. This enzyme is crucial in thwarting bacteria that attempts to enter our body cavities. By destroying the peptidoglycan layer of bacterial cell walls, it serves as a strong chemical defense against bacterial infections.
