Biology 1. If an interphase cell is treated with cyanide (a metabolic poison)‚ the cell does not divide by mitosis. However‚ if cyanide is added right after mitosis has started‚ the same cell completes mitosis. Which of the following explains this observation? A. Metabolic activity ceases during mitosis B. Cell division does not require metabolic activity C. Energy required for mitosis is produced and stored in the cell during interphase D. Mitotic cells make factors that make them resistant to

Further extraneuronal locations include among others lymphocytes‚ monocytes‚ and foetal tissue. 5-HT3 receptors modulate the release of neurotransmitters and neuropeptides like dopamine‚ cholecystokinin‚ acetylcholine‚ GABA‚ substance P‚ and serotonin itself. They have been demonstrated to be involved in sensory

OSTEOMYELITIS Definition: Osteo- derived from the Greek word osteon meaning bone‚ myelo meaning marrow and –it is meaning inflammation‚ simply means an infection of the bone or bone marrow that results in inflammation‚ necrosis and formation of new bone. Types: 1. Acute osteomyelitis - Bone infection develops within two weeks of an initial infection‚ injury or the onset of the underlying disease. 2. Sub-acute osteomyelitis - Bone infection develops within one to two months of an initial

Natural immunity is the immune system based on the genetic constitution of certain organisms. A person or an animal is born with one’s innate resistance against certain pathogen. At present‚ all immune systems require contact with antigens‚ and they acquire immunity accordingly‚ which is viewed as an outdated concept. There are three possible cases : 1.The antibodies of the parent are transmitted to their fetus through the placenta or colostrum‚ and the infant is also referred to as a passive immunity

immune to protect or limit the injury to it body. The adaptive immune response is antigen-specific and requires the recognition of specific "non-self" antigens during a process called antigen presentation. B cells and T cells are the major types of lymphocytes in the immune system. However‚ when an adaptive immune response develops against self-antigens autoimmune response occurs with the characteristic representation of specific autoantibody generation. The CNS autoimmune response is more complex since

affects horses. It is not contagious and symptoms of this disease are swelling of the eyelids‚ corneal edema‚ and blindness. There is no cure for this disease yet and the cause of it has yet to be discovered. Horses with acute uveitis and heavy lymphocyte influxation have a greater chance of developing ERU. When the condition is chronic‚ it can cause blindness‚ glaucoma‚ lens luxation‚ cataracts and retinal degeneration. Parasitic‚ bacterial‚ viral‚ and trauma can cause ERU as well. Leptospira ssp
