Three of the most prominent definitions of species are the biological species concept, the phylogenetic species concept, and the
morphological species (morphospecies) concept. drag each characteristic to the appropriate bin based on the species concept(s) to which it applies. view available hint(s) resethelp accommodates asexual reproductionnot applicable for extinct speciesused by scientists in classificationrelies on similarities in structurebased on evolutionary historyspecies acceptance criteria can be subjective biological morphological phylogenetic morphological and phylogenetic morphological, phylogenetic, and biological
We must first define these three prominent definitions of species. Biological species concept means that organisms resemble each other because of genes being passed from parent to offspring. Phylogenetic species concept means that organisms resemble each other because they evolved from a common ancestor. Lastly, morphological species concept characterizes species on the structure of their body parts rather than genetic or phylogeny.
In this case, (1) biological species concept is not applicable for extinct species, (2) phylogenetic species concept is based on evolutionary history, (3) morphological species concept relies on similarities in structure, (4) Morphological and phylogenetic species concept accommodates asexual reproduction, and lastly (5) all species concepts are used by scientists in classification.
Primary lymphoid organs: These organs include the bone marrow and the thymus. They create special immune system cells called lymphocytes. Secondary lymphoid organs: These organs include the lymph nodes, the spleen, the tonsils and certain tissue in various mucous membrane layers in the body (for instance in the bowel)
b. Aldosterone promotes sodium reabsorption in the kidneys.
Explanation:
Once it is produced by the adrenal gland it stimulates the mineralocorticoid receptors on the distal tubule and collecting duct of the kidney's nephrons. This causes sodium reabsorption in the kidneys indirectly affecting water retention.
Invasive species are among the leading threats to native wildlife. Approximately 42 percent of threatened or endangered species are at risk due to invasive species. These species were brout from other countries and they cause problems in these other countries or continents. Like the bees in america were not native and neither werer the cattle in the western hemisphere.
