Chemical formula is a way of presenting information about the chemical proportions of atoms that constitute a particular chemical compound or molecule, using chemical element symbols, numbers, and sometimes also other symbols, such as parentheses, dashes, brackets, commas and plus (+) and minus (−) signs. These are limited to a single typographic line of symbols, which may include subscripts and superscripts. A chemical formula is not a chemical name, and it contains no words. Although a chemical formula may imply certain simple chemical structures, it is not the same as a full chemical structural formula. Chemical formulas can fully specify the structure of only the simplest of molecules and chemical substances, and are generally more limited in power than are chemical names and structural formulas.
A gamete has one copy of each chromosome, it is haploid.
A gamete is a haploid cell produced during the process of meiosis, it fuses with another haploid cell during fertilization in sexual reproduction. May be therefore described as mature haploid (single copy of chromosome) male or female germ cell that unites with another haploid cell and forms a zygote.

<h3>What is the anatomy of Earthworm?</h3>
- An earthworm is a terrestrial invertebrate and a member of the phylum Annelida.
- They have a tube-within-a-tube body structure, corresponding external and internal segmentation, and typically include setae on each segment.
- They can be found wherever the soil, water, and temperature permit.
- The body of an earthworm is composed of a digestive tube and a thick cylindrical muscular tube that forms the body.
- The body is divided into segments, and furrows on the surface of the body serve as markers for the segment boundaries.
- The top of the first segment, which encloses the mouth, is a lobe made of muscle and flesh.
