01:30Accountability and Responsibility of a Nurse I
Accountability in nursing is a fundamental principle that underscores the obligation of nurses to take responsibility for their actions and answer for any errors or omissions in patient care. This principle is grounded in the professional, legal, and ethical frameworks that shape nursing practice. For instance, nurses must adhere to all relevant laws, regulations, and practice standards, including guidelines set forth by nursing boards and professional bodies, to ensure their actions comply...
01:09Accountability and Responsibility of a Nurse II
Professional accountability in nursing is a multifaceted concept that encompasses professional ethics, legal standards, and employment expectations. This framework ensures that nurses maintain and elevate the quality of care while upholding the values of their profession. It compels them to treat patients, families, and colleagues with respect, compassion, and integrity.
For example, a nurse demonstrating respect and compassion might listen attentively to a patient's concerns, provide comfort...

02:23The Soil Ecosystem
Plants obtain inorganic minerals and water from the soil, which acts as a natural medium for land plants. The composition and quality of soil depend not only on the chemical constituents but also on the presence of living organisms. In general, soils contain three major components:
02:35Key Elements for Plant Nutrition
Like all living organisms, plants require organic and inorganic nutrients to survive, reproduce, grow and maintain homeostasis. To identify nutrients that are essential for plant functioning, researchers have leveraged a technique called hydroponics. In hydroponic culture systems, plants are grown—without soil—in water-based solutions containing nutrients. At least 17 nutrients have been identified as essential elements required by plants. Plants acquire these elements from the atmosphere, the...
02:34Water and Mineral Acquisition
Specialized tissues in plant roots have evolved to capture water, minerals, and some ions from the soil. Roots exhibit a variety of branching patterns that facilitate this process. The outermost root cells have specialized structures called root hairs that increase the root surface, thus increasing soil contact. Water can passively cross into roots, as the concentration of water in the soil is higher than that of the root tissue. Minerals, in contrast, are actively transported into root cells.
02:36Meristems and Plant Growth
Plants grow throughout their lives; this is called indeterminate growth, and it distinguishes plants from most animals. Although certain parts of plants stop growing (e.g., leaves and flowers), others grow continuously—like roots and stems.
