However, repercussions of effects such as the development of cancer cells and congenital disabilities have deterred the process. Further study on the topic can help determine whether there is light at the end of the tunnel and whether it is worth testing.

  • Importance of limnology to the ecology.

Limnology helps balance the ecology by sustaining wildlife and human life through the sustenance of water and offering habitation. Humans equally have a role in creating the balance by creating reservoirs and reducing water solutions, as its absence or tampering would gravely negate the natural equilibrium of the world by reducing essential food sources and endangerment of wildlife. This interesting presentation topic can offer more knowledge to students on its function. 

  • Benefits of renewable energy to the environment.

Unrenewable energy sources have largely contributed to negative environmental impacts. Coal, for example, contributed to about 60% of carbon emissions within the USA. Renewable sources such as the sun would reduce the environmental impact and be sustainable without depletion over the years. In line with the ‘save the planet’ agenda, renewable energy sources would enormously impact the environment.

  • Biology impact of dopamine.

The science of joy and happiness largely contributes to the human release of the dopamine hormone. Aside from this, the hormone magnifies other functions of the brain and affects aspects of our daily life such as mood and decision making, and by effect, may also affect brain memory. Understanding its impact can help discover its association with diseases such as Attention Deficit Hyperreactive Disorder (ADHD) and the basis for determining dopamine levels in the body.

  • The reaction of human beings to shock.

The human body is a knit of body cells and the neurotransmission of information which subsequently triggers a result. A study on this topic can realize several body actions and impulse reactions that would not have previously been regarded as reactions to shock. This presentation would educate students on various levels of shock, subsequent reactions to the shock, and ways others can help people come out from shock.

  • Comparison of chemical and natural fertilizers.

Modifications and advancements have introduced crucial materials and substances necessary for plant growth. However, with the hindsight of traditional farming methods, questions arise on how health and produce were maintained without integrating modern technologies. For example, a comparative study on the difference between natural and chemical fertilizers can be studied to liken the quality and quality of products to other factors, such as the food production span.

  • The extent of threat on global warming.

Articles, global agendas, documentaries, and sustainable measures on global warming have been taken to highlight the effect of global warming. However, through the smaller base of the class focus, this BIOLOGY TOPIC FOR PRESENTATION can help bring the seriousness of this burden closer to home. Through photos and citations of recent events, the extent of global warming can be clearly outlined and defined, thus triggering change.

  • Organic farming.

Plant modifications and alterations to trigger produce have taken a spike, and there is little information and proof on whether the methods used are safe. For example, the debate on genetically modified has emerged mixed emotions among people due to the uncertainty of their impact on human bodies. Organic farming, however, borrows traditional agriculture, which inhibits the use of chemicals or fertilizers on consumable plants. The methods promote waste recycling, nature preservation, and reduced agricultural food production.

  • Use of nanoparticles in cancer therapy.

Cancer cells have robbed the lives of individuals and brought immense sadness to many others. Despite years of research in pursuit of a solution, no method has been proven adequate to cure cancer cells. Therapy methods have been resorted and proved significant in the shrinkage of cancer cells. Nanotechnology is the utilization of microscopic materials in the health care industry. Nanotechnology has mainly been utilized in the medical world to send medicine and drugs to specific areas and trigger formation of antibodies through a prompt on the immune system. In cancer therapy, the technology can be used in diagnosis by producing clear images through MRI and ultrasounds.

  • Relationship between gene mutations and neurological disorders

The nervous system allows communication between the brain and the body through neurotransmission. Body functions such as coordination of muscles, speech, emotion, and memory are made possible through electric signals between the brain and nervous system. Mutation in DNA can cause difficulty in the standard mention latter and thus cause complications such as Alzheimer’s, epilepsy, deafness, and Parkinson’s disease. This biology presentation topic for college can allow students to understand the relationship and identify people suffering from gene variations.

  • Role of hormones in mate selection of animals.

Animal biology forms a very intriguing biology topic for presentation. The marking of mates and the reproduction process is highly intuitive to animals but has several hormones attributed to its occurrence. Pheromones involved in mate selection are specific to animals of a specific species and vary their behavior from one class to the other, differs. Understanding how the male and female hormones distinguish from one another and the associated result they trigger could form an enthralling, eye-opening presentation.

  • Colony collapse disorder of bees

Current ecology matters can also form a basis for a biology college presentation. Bees are vital to plant production through pollination, and a threat to bee colonies offsets the ecological balance and adversely affects humans. Since 2006, the colony collapse disorder of bees has been reported, where adult bees leave the hives simultaneously, leaving the queen bee and some immature bees by themselves. The disorder has been attributed to factors such as pesticides and poor nutrition, but a presentation can bring more understanding of other causes. 

  • Communication of the gut and the brain.

Process such as the swallowing stimulus is triggered through an associated communication of the gut and the brain. This presentation can help understand other examples of processes emanating from this communication. More information can also be obtained from this enteric and central system.

  • Purpose of endocrine disruptors to human health.

Endocrine disrupters are chemicals that interfere with body hormones and may be artificial or natural. The endocrine disrupters, therefore, affect body health and bring about complications such as diabetes and thyroid problems. Therefore, a presentation on the sources of endocrine disruptors and how to avoid them can be studied.
