Explanation:

The letter to my parents describing how I received my genes.

Dear Parents,

Hi, Mum and Dad. I hope you are all doing well. I am writing this letter to satiate your curiosity on how I received the genes I now possess and how I look the way I do now.

Firstly, all living organisms including we, humans, contain genetic material in form of DNA, through which genetic information is expressed and transferred to offsprings. This DNA which contains functional segments called GENES, are transferred in humans (like us) via gametes or sex cells.

The sex cells are produced by the process of meiosis, a cell division that divides each portion of the DNA containing all genes into gametes. These gametes (sperm and egg, in male and female respectively) fuses in the process of fertilization to form a zygote, which contains all the necessary genetic information from both parents (mother and father).

This further explains why I look like either mum or dad because i contain in my genome both of your genes.

before, trains worked using the steam engine. thus, it uses heat so it is crucial to apply heat balance. the steam engine absorbs energy during the stage of boiling water. so, this is the endothermic reaction. when the steam is used to work the piston, it has to release this energy through running the train. the excess energy is released as an exhaust to the chimney. this is the exothermic process because it releases energy to the surroundings.
