Answer: It helps in the removal of abnormal heart rhythm
Explanation:
The AHA's chain or survival includes many steps in it. This is required to save the life of a person in emergency conditions.
One of the main step in AHA's chain of survival includes Rapid defibrillation which is given to a person after CPR.
This condition eliminated the abnormal cardiac rhythm. Electric shocks are given by the medical team so as to treat the emergency conditions like heart attack, cardiac arrest, et cetera.
Answer:
A
Explanation:
Prairies are unique ecosystems dominated by grasses and other non-woody plants called forbes. ... A prairie ecosystem includes all the living components-- plants and animals--and all the nonliving components-- sun, water, fire, soil, and--nutrients.
The vegetation type is called STEPPE. Steppe refers to the vegetation type in which there are only grassland plains; no trees exist in this eco-region. The countries of the world where this type of vegetation can be found include Russia, Ukraine, Hungary, etc. The steppe biome is a cold, dry grassland that exist in all the continents of the world except in Australia and Antarctica. Humidity level is usually very low in this biome because they are usually located far away from the ocean.
Answer:
The answer is XX.
Explanation:
Let us say that X is the dominant gene and x is the recessive gene for the height of the pea plants. Pea plants need to be homozygous or heterozygous to have the short phenotype which means it needs to have the genotype xx or Xx.
The F2 offspring has a ratio of 74,5% tall plants and 25,5% short plants. For these results, the stem height pea plant needs to be homozygous which is an XX genotype for the tall pea plant.
I hope this answer helps.
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.
