Cubic Formula Proof https://youtu.be/Ne6ITwP6qg0

In this video I go over a complete derivation of the cubic formula, which is the solution to the cubic equation. 

Animal Form and Function: Nutrition and Digestion https://youtu.be/exdSZXNzLko

In this video I discuss how animals obtain energy and nutrients from food via the digestive system. Animals are heterotrophs since they feed on other living organisms for energy and organic compounds.

Animal Form and Function: Water and Salt Balance https://youtu.be/62f3xi8BCZs

In this video I discuss how animals regulate their body fluid composition. Vertebrate animals have kidneys which filter out blood plasma and expel the waste as urine through the urethra. In contrast, aquatic animals have diverse fluid compositions relative to their environment.

Plant Development: From Seed Germination to Plant Growth https://youtu.be/VsbW1U1uz1Y

In this video I go over plant development which is governed by environmental signals and internal biological factors such as receptors, hormones, and the plant's genome.

Plant Nutrition and Transport: Hydroponics, Osmosis, and Translocation https://youtu.be/ojke-1F33o8

In this video I explore the mechanisms by which plants transport water and nutrients. Essential nutrients for plant growth and reproduction are identified through controlled hydroponic experiments, which often use aqueous solutions instead of soil.

Comparison of Conventional and Genetic Vaccines https://youtu.be/izg0PP2rUgc

In this video I go over the mainstream theory of how various types of vaccines work. Conventional vaccines include protein subunits (spike proteins), virus-like particles, and whole virus vaccines. Novel genetic vaccines include DNA, messenger RNA (mRNA), and viral vector vaccines.
