ANSWER: The presence of cork cambium depicts that the plant has undergone secondary growth.
EXPLANATION: Cork cambium is also referred to as is also known as Phellogen (a meristematic cell layer). It is found in vascular plants and located in the peridermis.
However, presence of cork cambium indicates that the plant has undergone secondary growth, which is elicited as a result of cell division in the cambia or lateral meristems, which in turn causes the stem and root to thicken.
Answer:
a. are probably built by different genes.
Explanation:
Although sharks and dolphins are aquatic animals belonging to the vertebrate group, sharks are fish while dolphins are mammals. Sharks belong to the class Chondrichthyes which are fish that have a cartilaginous skeleton. On the other hand, dolphins are mammals (class Mammalia) which are animals mainly characterized by the presence of mammary glands. In consequence, both species are not closely phylogenetically linked, thereby those genes involved in the development of the integumentary system (skin) in both species are expected to be different.
Answer:C) The blue star is hotter than the red star
Explanation: Blue fire is usually an indication of the hottest type of fire the range of temperature being 2,300 to 3,000 a real life example of this is if you light a lighter the bottom of the flame is blue and that part is the hottest part of the flame.
Answer:
La pared de la célula vegetal, es un recurso evolutivo para adaptarse y sobrevivir al medio, la célula animal no requiere la presencia de pared por eso sus características son diferentes debido a sus necesidades, no creo que la desarrolle, puesto que tener pared no la va a hacer avanzar o evolucionar para perfeccionar la especie, actualmente la célula animal contiene una membrana que le permite realizar proceso con mayor facilidad, como la consecución de nutrientes, procesos de excreción, reproducción y movilidad, dentro de un organismo como el hombre sería inviable este mecanismo, sin embargo hay especies que se han adaptado y tienen paredes en su superficie como el caso de las algas y las bacterias, teniendo en cuenta estos seres como ejemplo se sabe que una de las ventajas de tener pared es la resistencia a lesiones como las provocadas por antibióticos, soportan fuerzas osmoticas e intervienen en el crecimiento, convirtiéndose en una armadura para el resto del organismo, de este modo sería como beneficiaría a la célula animal.
