The concentration of water is greater outside the cell than inside the cell
This is an example of vestigial structure.
Vestigial structures are structures (cells, tissues and organs) found in an organism that has lost most or all of its primitive function through evolution. The vestigial structure has performed vital functions in the organism in the past but as there are changes in species as a result of natural selection, the structure became less important until it no longer functions. A reduced nonfunctional digit on the paws of dogs known as a dewclaw is an example of vestigial structure.
Answer:
1. El corazón se localiza en el mediastino, que es el espacio comprendido entre ambos pulmones. 2. El miocardio es la capa funcional del corazón, puesto que su contracción impulsa la sangre hacia los pulmones y los demás tejidos. 3. Internamente el corazón presenta 4 cavidades: 2 cavidades superiores llamadas auriculasy dos cavidades inferiores conocidas como ventriculos . 4. Entre la aurícula y ventrículo del mismo lado se encuentran las válvulas auriculoventriculares. En el lado derecho tenemos la válvula tricuspide, mientras que en el lado izquierdo se encuentra la válvula mitral . 5. El ciclo cardiaco comprende dos fases, una de contracción o sistole y una de relajación llamada diastole.
Explanation:
El corazon es un organo con un tejido muscular liso especializado donde estas celulas musculares presentan uniones desmosomales de amplia conexion para la diseminacion rapida de señales, es asi como se producen contracciones ritmicas, autonomas y de manera simultanea.
El corazon a su vez presenta su auto irrigacion propia por medio de las arterias coronarias que se encargan de mantener el miocardo en buen estado de vitalidad.
Answer:
Termites can spend time building mounds there by aerating the soil and allowing moisture which support the growth of shrubs, grasses, tress.
Through their mounds, their droppings contain phosphorus and nitrogen which add to the soil nutrients and supports grasses, shrubs and trees growth.
Explanation:
Termites are commonly found in Savannah ecosystem in African areas and they build mounds. Termites mounds consist of their fecal droppings , saliva and clay.
Termites can spend time building mounds there by aerating the soil and allowing moisture which support the growth of shrubs, grasses, tress.
Through their mounds, their droppings contain phosphorus and nitrogen which add to the soil nutrients and supports grasses, shrubs and trees growth.
