Expository essays aim at explaining some reality by examining facts and providing real-world examples. We offer expository essay sample on the topic “The Chemistry of Love” for you to review how the topic is developed in compliance with expository writing requirements.

In literature, love is often described as an uplifting feeling. Poets, writers, artists, and even philosophers have been trying to determine the reasons and origin of the feeling as well as ways and recipes for dealing with it. Yet, the reality of the 21st century has made people more pragmatic. They have started looking for biological origins and explanations of love. Due to technological advancements, scientists are now able to investigate and present valid proofs of chemical foundation of love.

The Chemistry of Love

According to Dr. Fisher, an anthropologist from Rutgers University, love represents a holistic system that can be further divided into three subsystems. These are sex drive, romantic love, and attachment. Sex drive makes an individual look for a partner, while romantic love makes a person stay focused on only one particular partner. Attachment is the last factor in the chain and it makes the individual seek lasting relationship with the selected partner.

However, neither sex drive nor attachment or romantic love could exist without a driving force that impacts human behavior. Although love is commonly regarded in psychological terms, no one would argue that it does not involve hormones. Namely, involvement of hormones justifies the expression “chemistry of love.” Testosterone and estrogen cause sex drive in people. Dopamine and serotonin evoke the attraction stage, which is called romantic love. Oxytocin and vasopressin sustain attachment.

Female and male hormones of estrogen and testosterone evoke lust and sex-relate reactions that make individuals look for a partner. These hormones are responsible for sex drive. Some specialists assert that namely estrogen and testosterone induce romantic feelings due to influx of dopamine and serotonin into the brain. These hormones are involved in arousing euphoric feelings and good mood. Being in love is often compared to being high since the very same hormones involved in arousing sex drive and romantic love are secreted after taking drugs. Thus, individuals feel happy and may act impulsively under the influence of these hormones. The most lasting stage of love is attachment, which is driven by oxytocin. This hormone is responsible for the connection between a mother and a child, and it is secreted when two partners get intimate. Namely for this reason, serious relationships are attributed with tenderness rather than turbulent and abrupt feelings.

Thus, all of the presented facts about physiological reactions literally explain the meaning of expression “chemistry of love.” Consequently, love is more than solely psychological process; it is also a result of physiological reactions to the influx of different hormones during different stages of relationships. All the three stages of the feeling are regulated by different hormones. Thus, sex drive involves estrogen and testosterone to make a person look for a partner; dopamine and serotonin regulate romantic love, which later develops into the attachment under the influence of vasopressin and oxytocin. Although love is considered to be a sublime psychological emotion and feeling, it has much common with human biology and chemistry.

My friend told me a secret. He orders all papers on your website and recommended to do the same for me. I was very shy and afraid that my teacher would find it out. Eventually, I decided to ask your writer complete a lab report and got superb results! It is exactly what I needed.

I like to compose essays, but sometimes my part-time job makes me devastated and exhausted that I do not have time to sleep. My friend told me that students can purchase papers online. I was a bit afraid to do it, but your company sent me the best paper! Will surely order more papers because your prices are really cheap!

Karen

I used to buy papers from other companies and every time I was more and more disappointed. Eventually, I found your company that made me happy! Even if I give a very short deadline, your writers still manage to send me the paper with interesting content. Thank you for support.

Ryan

I had a surgery and could not study for a long time. I missed many tests, exams, quizzes, and did not submit writing assignments on time. I thought I would fail every class, but then I found your website. I was wondering if you specialize in all subjects and your support team assured me that every single piece of writing can be completed by writers.

Jeff

Your writers always send me papers on time. I have never achieved such good grades in my classes!

Jack

I purchased a couple of essays from two writing companies, who cheated and sent my fully plagiarized papers. They definitely do not offer “custom” writing. I found your company and read a couple of reviews. I placed a “trial” order to see if you would send me the paper at all. I was shocked to see such a well structured and well written paper!

Abraham, MO

“I thought I was taking a risk ordering a paper from your writing company. But it all turned out very nicely, thank you.”

Jill, KS

“I’m thankful for the support you gave me. Your service is the best!”

Olivia

I used to purchase papers from different online writing services, but I didn't receive what I paid for. Every time, I got lame excuses that they would send me the paper a bit later or they were sorry for the plagiarized content. Then I decided to look further and found your writing service. Your writer managed to complete the paper timely. I really appreciated it.

Sophia

You completed my research paper very fast. I used your paper as the basis of my further research project. I am very thankful for your support and everything you have done for me!

Alexis

I did not think that online writing services actually help. I purchased a book review and your writer made my professor put an A. I was deeply impressed. I am so proud of you! You definitely represent the best writing service because your writers pay attention to the quality of writing. Wonderful service!

Mia

I had to write an admission essay to get a grant in one of the local colleges. I thought it was impossible because my writing skills are very poor. I placed an order and got a perfect essay! Thanks!

Helen, VT

“I’m happy you followed my instructions so closely. I appreciate that a lot.”

Stacy

I always try to do all the homework on my own. However, I can't succeed in studying and always get very poor grades and negative feedback. I contacted you with a question if you could write an essay for me. You have good prices, I am always pleased with the quality and content of your papers.

Elizabeth

I completely forgot about an essay in management. Our teacher is very strict and does not allow late submissions. I thought I would fail the task. But I found your website and purchased the paper. Believe it or not, your writer coped with my essay in 3 hours only! How is it possible? I do not know, but I got an A+!

Aiden

For me, academic writing is the biggest obstacle on my way. I can pass all kinds of tests and exams. However, writing essays and other assignments is very time-consuming and daunting. I found a company that offers affordable prices for academic papers. Thank you for assisting me with all my home assignments. Your writers are genius!

Tess, IA

“Hi there, many thanks for the superb effort you put into my paper. Really appreciate it!”

I was very afraid to use your company services because it was my first experience. I am very bad in writing and always suffer from failing grades. Please tell to my writer #5720 that she is the best! I will definitely ask to complete more orders for me. Your company is definitely worth considering for other students.

Emma

I asked my writer to send a draft first. I got it and did not even ask to revise anything. In cases when I have little time or simply do not have any chance to submit a paper that follows teacher’s instructions, I always ask your writers to help and they have never let me down.

Logan

I am very thankful to your writers who are very professional and punctual. They have never missed my deadline. I have dealt with a couple of writers and did not face any essays. You are seriously the best writing service!

Stacy

I was devastated when my teacher told me that a research paper takes 60% of the final grade. Failing the paper means failing the whole course. I was depressed because my previous assignments were graded rather lowly. Your company helped me solve the issue. Thank you so much for that! I handed in a good research paper and got a favorable feedback!

Michael

I used to spend days and weeks in the library, searching for appropriate sources for my essays and research papers.

Carlos

I was very shy to order any papers online and thought that every student should diligently do homework. But when I found out that most of my classmates get A grades only because they purchase papers online, I also decided to do it. It was the first time I got an A+!

Kim

I did not think that you can complete an order within a few hours. You sent me the paper exactly on time, without any delays, though I chose a very sophisticated and boring topic. You saved my life! I will definitely use your writing services in the future. I have read many reviews of your services and they indeed show how professionally you work.

This year was very difficult for me because I had to work part-time and take care of my sister.

Steven

My best wishes to your writers! I am so thankful that I do not know even how to express my emotions. My teacher always gave me very low grades with comments that I am overlooking some instructions.
