Answer:
Lipids are hydrocarbon molecules that make up the structure of living beings. Few examples are <u>fats, oils and waxes</u>. Steroids are also a class of lipids but they are not structurally related to other lipids but do share some common properties with them. They are <em>insoluble in water and are hydrophobic</em>( water-repelling).
Explanation:
Lipids are insoluble in water as they are <em>non-polar</em> but soluble in non polar solvents (<em>chloroform</em>). Fat soluble vitamins like <u>A,D,E,K and steroids</u> have a different structure composed of fused four rings.
The most common example of steroid is cholesterol. Cholesterol acts as a precursor for many hormones and other signalling molecules.
Answer:
The envelope is an outer lipid bilayer that is studded with proteins. The function of the envelope is to identify and bind some receptor sites on the host membranes. After fusing with the cell membrane, it allows to capsid and genetic material to enter the cell and infect it.

The correct answer is: b. phosphorus and nitrogen
Plants use organic matter nutrients that produce by their own and thus we classified them as autotrophs (or self-feeders). But, they also require inorganic nutrients such as nitrogen and phosphorus and often one of them is special nutrient needed for growth and because of that called the limiting nutrient.
The fertilizers that people apply to farm fields, gardens and lawns contain phosphorus and nitrogen.
