<h3><u>Explanation:</u></h3>
DNA is described here as the instructions that governs all the characters of an organism. Its actually a macro molecule which is a polymer of different thousands of nucleotides which is present in all cells and contain genetic information for running the characters of an organism.
Genes are described here as series of nitrogen bases governing a particular character or trait. Gene is actually a functional part of DNA which codes for a protein that governs a particular character of an organism.
Enzymes are proteins in nature. They are produced as a result of transcription and translation from DNA, and hastens different chemical processes of a metabolic activity.
The chromosomes are the condensed form of DNA. They are seen in the cells prior to cell division, either mitosis or meiosis. They are half obtained from father and the other half from mother, leading to variations among the offsprings.
The name for all organisms that get their nutrients and energy from other organism are called parasites.
Mutualism- in which two different organisms interact, and each organism benefits each other (think "positive, positive"; or " +,+ ").
An example would be Oxpeckers and zebras or rhinos - In this relationship, the oxpecker (a bird) lives on the zebra or rhino, sustaining itself by eating all of the bugs and parasites on the animal.
The bird benefits by having a readily available source of food.
The zebra or rhino benefits from having the bugs removed. Also, when there is a danger to the zebra or the rhino, the oxpecker flies high and makes much noise in order to alert nearby animals to the impending danger (i.e. a predator).
