Answer:
Si los continentes no se han movido, entonces esto sugeriría una capa de hielo que se extendía desde el polo sur hasta el ecuador en este momento, lo cual es poco probable ya que el Reino Unido en ese momento también estaba cerca del ecuador y tiene extensos depósitos de carbón y piedra caliza. Si los continentes del hemisferio sur se vuelven a ensamblar cerca del polo sur, entonces la capa de hielo Permo-Carbonífero asume un tamaño mucho más razonable. Más evidencia proviene de las estrías glaciales, arañazos en el lecho rocoso hechos por bloques de roca incrustados en el hielo como el glaciar se mueve. Estos muestran la dirección del glaciar y sugieren que el hielo fluyó desde un solo punto central.
Answer:
The correct option is : a. Identification of the cell
Explanation:
The cell membrane, also called plasma membrane, is a semi-permeable membrane surrounding the cytoplasm of the cell, that protects and separates the interior of the cells from the external environment.
The carbohydrate layer of the cell membrane is known as the glycocalyx. In eukaryotes, <u>the carbohydrates present on the surface of the cell membrane play a important role in the cell-cell recognition and share information.</u>
Answer:
Option A, Acquisition
Explanation:
The first stage of learning is known as acquisition. It causes establishment of responses by pairing of Neutral stimulus, conditioning and un-conditioning stimulus. Once the association between a neutral stimulus and conditioned stimulus is established, the responses are acquired.
For example – If a bird is trained to pick a key whenever there is a sound of a bell, then after certain period of time an association will be established between the “ringing of bell” and “picking up of key” activity. Therefore, whenever the bird will hear the ringing sound it will search for key to be picked.
Thus, option A is correct.
