Sympatric speciation is the evolution of a new species from a surviving ancestral species while both continue to inhabit the same geographic region. In evolutionary biology and biogeography, sympatric and sympatry are terms referring to organisms whose ranges overlap so that they occur together at least in some places.
Answer:
Ecological pyramid is a graphical representation showing the biomass or bioproductivity at each trophic level in a given ecosystem.
Limitations
The ecological pyramid does not take into account the same species belonging to more than one trophic level.
The protein inside (a) red blood cells that carries oxygen to cells and carbon dioxide to the lungs is (b) hemoglobin. Hemoglobin is made up of four symmetrical subunits and four heme groups. Iron associated with the heme binds oxygen.
Since non-polar molecules are equally distributed and positively charged atoms in contrast with polar molecules. Thus, like fats oils and waxes, these materials are composed mainly of lipids or in the group of fats and are conspicuously insoluble with water. How do these substances interact with water? They are hydrophobic, thus, they don't "mix" with water. Unlike water and other polar molecules that are unequally and negatively distributed and charged making them able to bond with other molecules like oxygen and other polar molecules and substances.
Answer:
Molecular, Microscopic, Cell, Tissue and Organ levels
Explanation:
The natural strength production needed for skeletal muscle to function occurs at the molecular level. You can develop a better knowledge of the properties of cells and tissues by simply studying the molecular systems common to the cells in question. The different muscular level down to myofilaments are:
-
Molecular level — actin and myosin
- Microscopic level — sarcomere and myofibrils
- Cell level — myoblasts and myofibers
- Tissue level — neuromuscular intersections and fascicles
- Organ level — The key skeletal muscles of the body
