<span>Red tides are formed by dinofllagelata, eucaryotic flagellate organisms. Dinoflagellates are marine plankton which means they drift on the surface of the sea. Those are small, nonmobile organisms who sometimes bloom in concentrations of more than a million cells per ml. The bloom is often red colour so the phenomenon is called red tides. </span>Under such circumstances, they can produce toxins, dinotoxins<span> which are capable of killing fish, so that's why this occurrence is dangerous.</span>
Provide sperm to fertilize the eggs in the female reproductive system.
Answer:
plants grow taller in generations level because the vascular tissue can transport nutrients throughout the body even when it it necessary to go against gravity.
Explanation:
Answer:
The respiratory epithelium is a type of ciliated pseudostratified columnar epithelium.
Explanation:
The epithelium (a type of tissue) lines the blood vessels and inner-outer surfaces of organs. Their function includes protection, secretion, absorption, transport, etc. Based on the shape, they are classified as squamous, columnar, and cuboidal. Also, they can be simple epithelium (a single layer of cells) or stratified (layers of two or more cells).
Respiratory epithelium (airway epithelium) is a type of ciliated pseudostratified columnar epithelium. It is the epithelium that is found in the respiratory mucosa and lines most of the respiratory tract. It protects and moist the airways. It prevents infection by the self-cleaning mechanism of the airways (mucociliary clearance) and thus acts as a barrier to pathogens and foreign particles. It also secretes mucus and prevents tissue injury. The respiratory epithelium contains four types of cells-ciliated, goblet, club and airway basal cells. The arrangement of these multiple cell types as a single layer results in the non- alignment of their nuclei in the same plane. So the epithelium appears as layered or stratified. Hence the name pseudostratified or falsely layered.
Well an increase in alkaline causes pH levels to rise. When the levels of acid in your blood are too high, it's called acidosis. When your blood is too alkaline, it is called alkalosis. Respiratory acidosis and alkalosis are due to a problem with the lungs.
