Primary Production01:06

Primary Production

25.1K
The total amount of energy acquired by primary producers in an ecosystem is called gross primary production (GPP). However, of this energy, producers use some for metabolic processes, and some is lost as heat, decreasing the amount of energy available to the next trophic level. The remaining usable amount of energy is called the net primary productivity (NPP). In terrestrial ecosystems, NPP is driven by climate, while light penetration and nutrient availability drive NPP in aquatic ecosystems.

Primary Active Transport01:47

Primary Active Transport

197.4K
In contrast to passive transport, active transport involves a substance being moved through membranes in a direction against its concentration or electrochemical gradient. There are two types of active transport: primary active transport and secondary active transport. Primary active transport utilizes chemical energy from ATP to drive protein pumps that are embedded in the cell membrane. With energy from ATP, the pumps transport ions against their electrochemical gradients—a direction...

Primary and Secondary Growth in Roots and Shoots

60.3K
Vascular plants, which account for over 90% of the Earth’s vegetation, all undergo primary growth—which lengthens roots and shoots. Many land plants, notably woody plants, also undergo secondary growth—which thickens roots and shoots.

Primary Distribution

534
Primary distribution systems deliver electrical power from substations to consumers through various voltage classes, with 15-kV class voltages being predominant among U.S. utilities. Older 2.5- and 5-kV classes are being replaced by 15-kV primaries, while higher 25- to 34.5-kV classes are used in high-density urban areas and rural regions with long feeders. Three-phase, four-wire multigrounded systems are widely employed for balanced power delivery, using the neutral wire as a grounding point.

Primary Lymphoid Organs01:16

Primary Lymphoid Organs

14.8K
Primary lymphoid organs are pivotal in the formation, development, and maturation of lymphocytes, the white blood cells that serve as the backbone of our immune system. This crucial function underscores their fundamental role in maintaining our overall health and immunity. The two primary lymphoid organs of prime importance are the red bone marrow and the thymus.
The red bone marrow is a soft, spongy tissue nestled in the interior of long bones such as the humerus and femur. It is the site...

    Area of Science:

    • Dermatology
    • Pathology
    • Skeletal Biology

    Background:

    • Osteoma cutis is a rare condition characterized by the presence of bone tissue within the skin.
    • Primary osteoma cutis develops spontaneously without an underlying inflammatory or traumatic cause.
    • Secondary osteoma cutis arises in association with various skin conditions or systemic diseases.

    Observation:

    • A 24-year-old woman presented with a small, hard subcutaneous tumor on her left breast.
    • Clinical examination and patient history revealed no other abnormalities or predisposing factors.
    • Histopathological examination confirmed the presence of mature lamellar bone within the dermis, consistent with osteoma cutis.

    Findings:

    • The histological features were typical of osteoma cutis.
    • The absence of other clinical findings supported a diagnosis of primary osteoma cutis.
    • This case represents a rare instance of primary cutaneous ossification.

    Implications:

    • This case contributes to the understanding of the rare condition of primary osteoma cutis.
    • It underscores the importance of histopathological examination for accurate diagnosis.
    • Further research may elucidate the specific mechanisms driving primary cutaneous ossification.
