BIOLOGY 1114H: Biological Sciences: Form, Function, Diversity, and Ecology

Explore what makes each element unique by focusing on the atomic components: protons neutrons and electrons. Learn why the number of protons known as the atomic number is the defining characteristic for each element's properties. Understand how protons set elements apart even as neutrons and electrons also play important roles.

Discover how filtration pressure is calculated within our bodies. Explore various options from adding capillary pressures to understanding lymphatic vessel roles. Grasp essential physiology principles as we highlight the accurate method.

Explore how viruses replicate and the various ways in which new viruses emerge. Understand the importance of mutation, cross-species transmission, and the significance of wider spread in host species for disease control strategies.

Dive into the biochemistry of haemoglobin, a pivotal protein in red blood cells. We assess key statements about its structure and function, clarifying common misconceptions.

Unravel the intricate relationship between histones and DNA. Learn how histones maintain DNA structure within the cell nucleus and understand the significance of charge attractions in DNA-histone binding.

Learn about the composition of arteries focusing on those closer to the heart. Understand the role of endothelium smooth muscle fibers elastic fibers and collagen in these arterial structures. Discover why arteries near the heart have a higher percentage of elastic fibers to withstand pressure changes effectively.
