This type of cell attacks tumor cells and infected cells by releasing chemicals that are toxic to the cell, resulting to cell death of the target cell.
The cell is defined as the fundamental, functional unit of life. Some organisms are comprised of only one cell whereas others have many cells that are organized into tissues, organs, and systems. The scientific study of the cell is called cell biology. This field deals with the cell structure and function in detail. It covers..
Plantlife can be studied at a variety of levels, from the molecular, genetic and biochemical level through organelles, cells, tissues, organs, individuals, plant populations, and communities of plants.

Physiology is the study of how living organisms function. Thus, human physiology deals specifically with the physiological attributes of the human body at various levels of organization, i.e. from cellular to tissue and ultimately, physiology at the biological system level. Human physiology is important because it imparts an in-depth understanding of the vital processes that..
Animals adapt to their environment in aspects of anatomy, physiology, and behavior. This tutorial will help you understand how animals adapt to their habitat. For instance, how animals thrive in aquatic habitat and are able to overcome osmosis. It also sheds light on the reasons animals adapt...
Regulation of Biological Systems tutorials are focused on the modulation of biological systems from cell to population levels. The course starts with the principles of negative feedback control, and how it regulates blood sugar, water, and temperature in humans. It, then, culminates in the population regulation and ecosystem succession. Learn the various regulatory mechanisms that..
