Genetics and the Human genome: In today’s study of nature and nurture, genetics has been an important aspect of nature’s control of life. It can be seen through the study of diseases, evolution, and the structure and function of our DNA. Geneticists and other scientists are constantly working to create better methods of examining and manipulating genetic information. They are also trying to figure out what the human genome is and how to use it for research purposes. The human genome is a set of DNA sequences that we are born with and which determine the characteristics of our bodies and brains.
Cell Biology: General biology also involves looking at cells in their natural state. Cells can be grouped into four categories; undifferentiated cells, differentiated cells, pre-formed cells, and specialized cells. Undifferentiated cells are those that grow and divide on their own. Derived from differentiated cells, these cells can have the ability to reproduce, secrete hormones and enzymes, and create tissue in the body. Pre-formed cells come from pre-formed tissues and organs, and specific cells are a special type of tissue that grows, multiplies, and divides in a laboratory setting.
Animal Physiology: This branch of science also falls under general biology. Animals are a large part of nature, as we see from the study of nature. For example, insects feed off of food, plants thrive on the food we eat, and animals live in the dirt, soil, and water we drink. They make up a major part of our world. From the study of animals, we learn about their physical and physiological systems and how they work together to keep us alive.
Animal Physiology/Experiments: While animal physiology does not always relate directly to humans, it does give us a window into their daily activities. The more we know about animals, the easier it is for us to understand how they live and do things. The field of animal physiology is the study of the functions, development, growth, metabolism, and physiology of animals and how they respond to environmental stimuli. They include everything from digestion to reproduction to behavior. From studying the anatomy and physiology of horses, to studying the physiology of dogs, and cats, to studying the physiology of fish, animals are essential in the study of the physical and chemical aspects of nature.
Nutrition: This is an area of animal biology that can relate to human nutrition. Animals are generally fed foods that they need to survive, grow, and reproduce, such as food, milk, meat, and vegetables. The study of how the food they eat interacts with their bodies and the environment can be used in the creation of new foods and nutritional supplements for humans. Nutritionists play an important role in human nutrition.
Evolution: This field of animal biology covers the biological processes that have shaped the history of the universe. It may seem somewhat boring, but it can be very fascinating to study the natural evolution of a species or an entire species through time.
Other branches of science: Humans are also involved in this branch of science. Biologists look into how our bodies work, how diseases affect them, how the environment interacts with the body, and its occupants, and how we interact with the environment, and the world around us. There are many ways that human biology helps us understand our place in the world, such as how we live in the present, how we can relate to the environment around us, how animals and plants react to us, and how we can benefit from nature and nurture it.
